AB  - The decrease of fossil fuel resources as well as associated pollution induced by its applications has
increased the interest in findings of renewable fuels from various biomasses such as wood, energy
crops, and various waste disposed from agricultural and food-industry activities. Especially
interesting is lignocellulosic waste (LCW) biomass, found in large quantities after processing of the
raw biomass, which pose certain energetic properties that might be used to fulfil future
sustainability demands. This paper describes the thermal decomposition of waste peach stones (PS)
investigated via thermogravimetric (TG) analyses. TG/DTG analyses provided a set of experimental
mass loss data (obtained under different conditions), which were modelled by different kinetic
models, resulting in parameters that might be used for industrial application of the tested biofuel.
The goal of analyzing the kinetics of thermal degradation was to establish a relationship between
the rate of degradation, degree of conversion (α) and temperature. In this sense, the investigation of
the kinetics of thermal degradation was performed in non-isothermal conditions, with the heating
speed varying from 5 to 20 ºC/min in an oxygen stream. Activation energy (Ea) of the PS thermal
degradation was determined using Flynn-Wall-Ozawa (FWO) isoconversional model free method.
The possible reaction mechanism that controls the process was investigated by the method of Coats-
Redfern (C-R). The values of the Ea obtained by this method were not constant with the change in
the degree of conversion (α), indicating that the thermal decomposition of PS represents a complex
process that cannot be described by a one-step reaction in the entire range of conversions. PS
waste samples investigated in this paper, have certain physical and chemical properties which
satisfy request for energy density, small ash content and safe burn out. Presented results might
support the value of biowaste in a future circular bio economy of Serbia.

AB  - Growing industrialization and non-renewable resource depletion have a huge impact on alternative clean up technologies
development, inducing investigation of the renewable, low-cost waste materials. Recently, lignocellulosic waste biomass,
generated at a large scale by different industries, appeared as an attractive feedstock worldwide, due to its abundance,
availability, multi-functionality and low cost. Since the fruits production has increasing trend all over the world,
generation of lignocellulosic waste such as fruit stones (that represent approximately 1/5 of the total fruit mass) became
a great environmental threat. In order to minimize negative impact on the environment, avoid greenhouse gasses emissions
and help in resource depletion by its renewable nature, it is necessary to explore its performances regarding its wide
application potential. Thermo-chemical conversion of lignocellulosic biomass in oxygen limited conditions, in order to
get biochar, has received a lot of attention recently. The biochar production requires lower energy inputs and less
expensive technology compared to activated carbon (estimation is that production cost of activated carbon are six times
higher than biochar costs).
In this paper, waste peach stones biomass was effectively converted into biochar at 500 °C under inert (Ar) atmosphere.
Pyrolysis was performed in Nabertherm 1300 muffle furnace for residence time of 1.5 h, with a heating rate of 10 °C/min,
while Ar was circulated through the sample at a rate of 100 mL/min. The raw biomass (PS) and obtained biochar (PS-B)
with particle size 0.1 mm < dp < 0.5 mm, were characterized by Scanning Electron Microscopy (SEM), Fourier transform
infrared spectrometry (FTIR) and Raman spectrometry to understand physicochemical changes which have been occurred
after pyrolysis. SEM analysis revealed the increased surface area due to the visible augmentation of pores and roughness.
FTIR analysis showed that many bands present in native biomass cannot be observed in biochar, due to the conversion or
removal of the most of the functional groups. Prominent bands have confirmed presences of aromatic compounds in
biochar: at 1592 cm−1 (C=C bond stretching derived from aromatic rings in the lignin), 1030 cm-1 (alcohol C-O stretching
vibration) and in the region 900 to 700 cm−1 (originating from aromatic compounds). These finding are in accordance
with results from Raman analysis, where D and G bands (at 1350 cm-1 and 1580 cm-1 respectively), indicate the presence
of poly-aromatic hydrocarbons.
Thermo-chemically modified biomass like this has a great application potential: as a pollutants sorbent, biofuel, soil
amendment, biocarriers, and in construction and electronic industries.

AB  - The mutual interaction of metal ions (lead, zinc and copper) on removal efficiency in binary and ternary systems, by biosorbent based on alkali treated apricot shells (Prunus armeniaca L.) was examined. The evaluation was done in batch system at two metals concentrations: 0.2 and 0.5mmol/ dm3. Tested biosorbent exhibited preferential uptake of lead in a multimetal systems. It is evident that mutual inhibition exists in all multimetal systems, but systems containing lead ex-hibited extreme inhibition toward copper and zinc ions. Process of sorption depends not only on specific chemistry of each metal, their affinity toward binding sites and the type of metal binding onto biosorbent, but also on sorbent chemical and morphological characteristics. In multimetal systems, tested sorbent showed preferential sorption orders: Pb (II)>Cu (II)>Zn (II).

AB  - Infant nutrition is essential for their growth and development. This research aims to determine the total antioxidant capacity of the infant food for preterm infants and indicate adequate methods for testing the quality and biological value of milk and infant food. The total antioxidant capacity (TAC) was determined in human milk and an infant formula for premature infants. The determination of the total antioxidant capacity was made using cyclic and differential pulse voltammetry, potentiometry and electron paramagnetic resonance spectroscopy. The results of three comparative electrochemical methods indicate that human milk has a higher antioxidant potential compared to infant formula, which contributes to better physiological development of the child. Fenton-based electron paramagnetic resonance spectroscopy method provides additional insight into TAC analysis, whereby a carbon-centered radical and an ascorbyl radical are formed in infant food. All methods can be used to determine TAC, since the results obtained individually with each method follow the same trend.

AB  - A low-cost waste biomass generated from a food industry, apricot shells, was subjected to alkali modification in order to compare morphology, crystalline structure and thermal stability of native and modified biomass, accompanied by their cellulose-rich fractions. The surface morphology and structure of compared samples were analysed by the scanning electron microscopy (SEM) and mercury porosimetry. Furthermore, Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD) and thermal analysis (TG/DTA) were applied. The results have shown that after alkaline treatment, inter- and intra-particle porosity in the material rises, resulting in increase of the total surface area. The XRD diffractograms showed that crystallinity index increased together with crystallite size, suggesting that modified sample has more ordered crystalline structure than native sample (also confirmed by the FTIR analysis). Although the cellulose-rich fraction extracted from the alkali-modified sample showed higher thermal stability, the overall thermal analysis revealed that alkali-modified biomass has lower thermal stability than the native sample. This indicates that this type of modification will improve the fuel properties of this lignocellulosic biomass and imply its possible application in energy recovery process.

AB  - Biosorption is evolving as a potential alternative to the
existing conventional technologies for the removal and/
or recovery of pollutants from aqueous solutions. The
present work investigates the possible application of
waste biomass Myriophyllum spicatum (Ms) in removing
contaminants, evaluating equilibrium through isotherms
of selected heavy metals: lead, copper, and
cadmium. As a heavy metal biosorbent, Ms was immobilized
in alginate beads (Ms: Alginate 2:1). Applied
biosorbent, MsA, was characterized by scanning electron
microscopy with energy dispersive X-ray spectroscopy
(SEM–EDX) and Fourier transform infrared spectroscopy
(FT-IR). Experimental results were fitted (nonlinear)
by six isotherm models: Langmuir, Freundlich,
Sips, Redlich and Peterson, Toth, and Temkin. For
lead(II) ion removal, fitting follows the following
sequence, F ≈ R-P > S > To > L > Te, while for copper(II)
and cadmium(II) ions are as follows: R-P > To ≈ Te ≈
L > S > F and R-P > L > To > S > F > Te, respectively. TOC
analyses revealed that M. spicatum releases 35.04 mg/L
of total organic content while immobilized sample, MsA,
only 6.81 mg/L. Finally, this biosorbent was tested on a sample of real wastewater from a coal-fired thermal
power plant complex TPP Kostolac (operated by PE
“Electric Power Industry of Serbia”). The results indicate
that using immobilized aquatic weed M. spicatum as
a biosorbent has a high potential for heavy metal wastewater
treatment applications.

and cadmium(II) ions are as follows: R-P > To ≈ Te ≈
L > S > F and R-P > L > To > S > F > Te, respectively. TOC
analyses revealed that M. spicatum releases 35.04 mg/L
of total organic content while immobilized sample, MsA,
only 6.81 mg/L. Finally, this biosorbent was tested on a sample of real wastewater from a coal-fired thermal
power plant complex TPP Kostolac (operated by PE
“Electric Power Industry of Serbia”). The results indicate
that using immobilized aquatic weed M. spicatum as
a biosorbent has a high potential for heavy metal wastewater
treatment applications.",

AB  - Water contaminated with diesel oil is one of the great challenges in waste water management. It is crucial to remove the water soluble fractions (WSF) from water in order to avoid toxic effects of these compounds and to meet the discharge regulations set by the environmental authorities. Biochar sorbents have generated a lot of attention as a new type of material due to their low cost origin and surface properties which lead to exceptionally high sorption capacities in water-pollution separation process. In this study, we have reported the synthesis and characteristics of novel biochar sorbent made from waste lignocellulosic biomass (peach stones) and evaluated its possible application in removal of WSF from synthetic wastewater. The synthesized biochar materials were characterized using scanning electron microscopy (SEM), Fourier (FTIR) and Brunauer, Emmett and Teller (BET) technique, while the elemental analysis was also done. Characterisation of peach stone biochar (PS-B) indicated multi porous high surface area (159.1 m2/g), with an average pore diameter of 2.66 nm. FTIR results indicated the presence of more aromatic compounds in biochar compared to peach stones. The sorption experiments were performed in batch system with mixing, with initial WSF of diesel components of 20 mg/L. The application of peach stone biochar (PS-B) resulted in more than 95% removal of diesel WSF, with reaching equilibrium after 5h of contact (under described operational conditions). Sorption mechanism can be described as multilayer chemisorption process, well described by Freundlich equation, which was also confirmed by pseudo-second order equation. Ecotoxicology tests have shown a decrease of toxicity of contaminated water on A. fischeri after the treatment of water by biochar sample. Therefore these forms of carbon based sorbents have great potential to be good sorbents of petroleum hydrocarbons WSF and can be successfully applied for their removal in water treatments

AB  - Water contaminated with diesel oil represents one of the greatest challenges in waste water management. Water soluble fraction (WSF) is of particular interest because of its toxicity to aquatic organisms and discharge regulations set by environmental authorities. Biochar sorbents have attracted great attention, due to their low cost origin and advantageous properties as well as high sorption capacities in sorption processes. In this study, we have reported the synthesis and characteristics of novel biochar sorbent made from waste lignocellulosic biomass (peach stones (PS)) and evaluated its possible application in removal of diesel WSF from synthetic water. Physiochemical characteristics of the biochar sample were analysed by scanning electron microscopy (SEM), Brunauer-Emmett-Teller (BET) method, and Fourier-transform infrared spectroscopy (FTIR), along with the elemental analysis. Characterisation of PS biochar (PS-B) indicated high multi porous surface area (159.1 m(2) g(-1)) with the average pore diameter 2.7 nm. FTIR results indicated higher presence of aromatic compounds in PS-B as compared to PS. The sorption experiments performed in a batch system using PS-B resulted in more than 95 % removal of diesel WSF, reaching equilibrium after 5 h. Equilibrium data were well fitted by Freundlich isotherm, while the pseudo-second order equation fitted well the kinetic data, indicating chemisorption involving valency forces through the sharing/exchange of electrons between the sorbent and PS-B. Applications of ecotoxicology tests based on a microbial biosensor (Aliivibrio fischeri) have shown a significant toxicity reduction of water sample after the treatment with biochar.

AB  - Concentrations of 10 potentially toxic trace elements were measured in soil samples collected from 18 sites in urban areas of Belgrade, the capital and the largest city in Serbia. Samples were analysed in order to assess the extent of soil contamination and to distinguish natural and anthropogenic input. The results demonstrated a general Zn, Pb, and Cd enrichment in surface samples, hence, after comparison with guidelines, it has been determined that there is a potential risk for human health. In the surface and buried samples, traces of cooper were detected. The highest concentrations of Cr (121 +/- 12.3 mg/kg) and Ni (94.9 +/- 12.6 mg/kg) were found at a sediment depth of 2 m and should be ascribed to geogenic sources. The results of HCA and PCA analysis supported a natural origin of Co, Cu, Mn, Cr, and Ni, while Cd, Zn, and Pb originated from anthropogenic inputs. Based on the pollution indices, Cd made the most dominant contribution, posing a high contamination risk in the studied area. Results of Nemerow pollution index (PIN) and potential ecological risk index (PER) demonstrated that pollution by heavy metals in sediments on several sites is moderately intense.

AB  - Procedures for solubilization of phosphorus from insoluble phosphates by acidophilic autotrophs and heterotrophs are considered to be research subjects of great importance in sustainable soil management, and could become, in the future, an alternative to current expensive methods of industrial fertilizer production. Furthermore, this biological production of fertilizer can be considered to be more environmentally friendly than current production methods. The object of this study was to investigate the possibility of phosphorus leaching from phosphate rock apatite using sulphuric acid generated from pyrite by iron-oxidizing Acidithiobacillus sp. B2, and to test the possible application of the mixture of these two minerals to produce a natural phosphate fertilizer. Iron-oxidizing Acidithiobacillus sp. B2 was isolated from copper sulphide mine wastewater (Lake Robule) in Bar, Serbia. The bacterium was identified by 16SrDNA oligonucleotide sequence and characterized using matrix-assisted laser desorption/ionization time-of-flight mass spectroscopy (MALDI-TOF MS). The leaching experiment was carried out in laboratory conditions at 28 degrees C for a period of four weeks. The results showed that up to 34.5% of the inorganic phosphorus was leached from the test mixture when in suspension with iron-oxidizing Acidithiobacillus sp. B2, while at the same time, the degree of leaching from a control suspension (without iron-oxidizing Acidithiobacillus sp. B2) was only up to 3.8%. Due to its low cost and environmental acceptance, treatment of soil with phosphate minerals in combination with pyrite and acidophilic iron- and sulphur-oxidizing bacteria could become an attractive and alternative way to improve the quality of alkaline soils.

AB  - Svakako jedan od još uvek aktuelnih problema u svetu, koji se javlja kao posledica prekomernog zagađivanja životne sredine, je i pojava kiselih kiša. Prekomerne emisije kiselih oksida iz procesa sagorevanja fosilnih goriva i metalske industrije, kao što su SO2 i NOx, su jedni od glavnih uzročnika ove pojave. U cilju da se skrene pažnja na ovaj još uvek aktuelan problem, i sagleda trenutno stanje, analizirana je promena sadržaja sulfata u atmosferskim padavinama u nenaseljenoj, ruralnoj oblasti u toku višegodišnjeg perioda. U ovom radu dat je pregled rezultata praćenja sadržaja sulfata u atmosferskim padavinama uzorkovanim na GAW/EMEP stanici 'Kamenički Vis'.

AB  - Acid rain is still one of the important and current issues arising from excessive anthropogenic pollution of the environment. Excessive emissions of acidic oxides, such as SO2 and NOx, coming from industrial combustion processes and metal industry are one of the main causes of this phenomenon. In order to highlight this issue and reflect on current status, annual change of sulfate content in atmospheric precipitation collected over ten year period in rural, unsettled area was analyzed. In this paper an overview of data collected during monitoring of sulfate content in atmospheric precipitation on GAW/EMEP station Kamenicki Vis is given. Ten year period, from 2000 to 2010, is covered and annual arithmetic mean sulfate concentrations are presented. Obtained data is also discussed in scope of European average levels of sulfate content in precipitation, trans-boundary deposition and total national emissions of sulfur oxides in Europe and Serbia.

abstract = "Svakako jedan od još uvek aktuelnih problema u svetu, koji se javlja kao posledica prekomernog zagađivanja životne sredine, je i pojava kiselih kiša. Prekomerne emisije kiselih oksida iz procesa sagorevanja fosilnih goriva i metalske industrije, kao što su SO2 i NOx, su jedni od glavnih uzročnika ove pojave. U cilju da se skrene pažnja na ovaj još uvek aktuelan problem, i sagleda trenutno stanje, analizirana je promena sadržaja sulfata u atmosferskim padavinama u nenaseljenoj, ruralnoj oblasti u toku višegodišnjeg perioda.

AB  - In this paper, an overview of data collected during monitoring of lead content in atmospheric precipitation on GAW/EMEP (Global Atmosphere Watch/European Monitoring and Evaluation Programme) station "Kamenički Vis", Serbia from 2000 to 2010 is given. Annual arithmetic mean concentrations, weighted arithmetic mean concentrations, and median of week samples are presented. Obtained data was compared with results of analysis of atmospheric precipitation collected on experimental EMEP station "Zeleno brdo", Serbia and discussed in the scope of European average levels of lead content in precipitation and air. Significant increase of average annual lead content in precipitation was observed in 2003 and 2007. The observed peaks cannot be seen on average European trends, thus leading to the conclusion that the recorded increases are characteristic for the local region. In order to further discuss the nature and direction of possible sources of detected lead pollution, a short analysis of lead emission data was performed. An effort was made to gather data from the countries that lay in directions from which dominant winds blow, as well as for Serbia. For this purpose, total national emissions from LRTAP Convention emission inventory report and EMEP emission inventory were used, as well as data published by relevant national authorities. According to these emission levels, the majority of the surrounding countries couldn't have contributed much to the recorded increases of lead content in precipitation. However, several possible sources were revealed. In all studied countries, emission levels steadily dropped during the analyzed period, whereas only for Serbia a different trend was observed. The presented data leads to the conclusion that the recorded increase of lead content in precipitation in 2003 probably originates from trans-boundary contributions, while increases in 2007 and onwards may come from Serbia's own emissions.

AB  - Precipitacija, a pre svega mokra depozicija, predstavlja jedan od najznačajnijih mehanizama za uklanjanje gasova iz atmosfere kojim se kontroliše njihova distribucija, koncentracija i životni vek u zemljinoj atmosferi. Formiranje i karakteristike precipitacije su pod snažnim uticajem atmosferskih (meteoroloških) uslova, međutim, značajnu ulogu mogu da imaju i zagađujuće materije, bilo da su nastale prirodnim ili veštačkim putem. Antropogene aktivnosti od industrijske revolucije na ovamo dovele su do značajnog povećanja koncentracija zagađujućih materija u atmosferi, a samim tim i do povećanog uticaja zagađujućih materija na osnovne meteorološke parametre. U ovom radu je dat pregled osnovnih zagađujućih materija koje nastaju ljudskim aktivnostima, a mogu da utiču na precipitaciju. U radu su razmatrane njihove karakteristike, način na koji nastaju i njihov uticaj na klimatske parametre. Posebna pažnja je posvećena konkretnim uticajima na mokru depoziciju, kao i promenama koje ona izaziva u životnoj sredini.
AB  - Precipitation and primarily, wet deposition represents one of the most important mechanisms for gases removal from the atmosphere, and thus for control the distribution, concentration and life-time of many gaseous species in the atmosphere. Formation and characteristics of precipitation are heavily influenced by atmospheric (meteorological) conditions, but pollutants arising from natural and artificial sources can also have significant role. Anthropogenic activities from industrial revolution up to now led to a significant increase in the concentration of pollutants in the atmosphere and, therefore to increased influence of pollutants on main meteorological parameters. The paper gives an overview of main pollutants resulting from human activities, which could affect the precipitation. The paper discusses their characteristics, the way they occur and their impact on climate parameters. Special attention was paid to effects of pollutants on wet deposition, as well as on changes it causes in the environment.

AB  - Postupci rastvaranja fosfora iz nerastvornih fosfatnih ruda pomoću acidofilnih autotrofa i heterotrofa spadaju u veoma bitna istraživanja, zbog moguće primene ovih ruda kao đubriva, čija je upotreba ekonomski i ekološki prihvatljivija od industrijskih fosfatnih đubriva. Predmet ovog rada je bio da se ispita mogućnost rastvaranja fosfora iz fosfatne rude sa ležišta Lisina (Bosilegrad), u laboratorijskim uslovima, dejstvom sumporne kiseline generisane pomoću bakterijske kulture Acidithiobacillus (At.) ferrooxidans, izolovane i selekcionisane sa jalovišta površinskog kopa rudnika bakra u Boru. Cilj eksperimenta je da se utvrdi da li je moguće rudu sa navedenog ležišta u kombinaciji sa ispitivanom bakterijskom kulturom koristiti kao prirodno đubrivo. Dobijeni rezultati pokazuju da se tokom eksperimenta rastvara fosfor iz ispitivane rude pod uticajem At. ferrooxidans i da je stepen rastvaranja 24,5 %, dok je rastvaranje fosfora u kontrolnoj suspenziji (bez At. ferrooxidans) iznosilo 7,2 %. Uticaj At. ferrooxidans na rastvaranje fosfora je potvrđen, tako da dalja istraživanja treba usmeriti na ispitivanja mikrobiološkog luženja mešavina apatita sa sulfidnim supstratima, zbog eventualne primene vezane za poboljšanje kvaliteta alkalnih zemljišta.
AB  - Phosphorus solubilization from insoluble phosphate ores by acidophilic autotrophs and heterotrophs is a research of significant interest, because of potential use of these ores as fertilizers, which are economically and ecologically more acceptable than industrial phosphate fertilizers. The object of this paper was to examine the possibility of phosphorus leaching from phosphate ore from Lisina deposit (Bosilegrad), by bacterially generated sulfuric acid, in laboratory conditions. The experiments were carried out with bacterium Acidithiobacillus (At.) ferrooxidans, which is isolated and selected from the copper sulphide mine in Bor. The main goal of the experiment was to confirm if it is possible to use phosphate ore in combination with examined bacterial culture, as a natural fertilizer. Results obtained show that phosphorus has been leached up to 24,5 % in suspension with At. ferrooxidans, and in the same time, degree of leaching in control suspension (without At. frrooxidans) was up to 7,2 %. Influence of At. ferrooxidans on phosphorus solubilization has been confirmed, so the future perspective of our investigations should be directed to examination of microbiological leaching of apatite mixtures with sulphide substrates, and their potential use in quality improvement of alkaline soils.

abstract = "Postupci rastvaranja fosfora iz nerastvornih fosfatnih ruda pomoću acidofilnih autotrofa i heterotrofa spadaju u veoma bitna istraživanja, zbog moguće primene ovih ruda kao đubriva, čija je upotreba ekonomski i ekološki prihvatljivija od industrijskih fosfatnih đubriva. Predmet ovog rada je bio da se ispita mogućnost rastvaranja fosfora iz fosfatne rude sa ležišta Lisina (Bosilegrad), u laboratorijskim uslovima, dejstvom sumporne kiseline generisane pomoću bakterijske kulture Acidithiobacillus (At.) ferrooxidans, izolovane i selekcionisane sa jalovišta površinskog kopa rudnika bakra u Boru. Cilj eksperimenta je da se utvrdi da li je moguće rudu sa navedenog ležišta u kombinaciji sa ispitivanom bakterijskom kulturom koristiti kao prirodno đubrivo. Dobijeni rezultati pokazuju da se tokom eksperimenta rastvara fosfor iz ispitivane rude pod uticajem At. ferrooxidans i da je stepen rastvaranja 24,5 %, dok je rastvaranje fosfora u kontrolnoj suspenziji (bez At. ferrooxidans) iznosilo 7,2 %. Uticaj At. ferrooxidans na rastvaranje fosfora je potvrđen, tako da dalja istraživanja treba usmeriti na ispitivanja mikrobiološkog luženja mešavina apatita sa sulfidnim supstratima, zbog eventualne primene vezane za poboljšanje kvaliteta alkalnih zemljišta., Phosphorus solubilization from insoluble phosphate ores by acidophilic autotrophs and heterotrophs is a research of significant interest, because of potential use of these ores as fertilizers, which are economically and ecologically more acceptable than industrial phosphate fertilizers. The object of this paper was to examine the possibility of phosphorus leaching from phosphate ore from Lisina deposit (Bosilegrad), by bacterially generated sulfuric acid, in laboratory conditions. The experiments were carried out with bacterium Acidithiobacillus (At.) ferrooxidans, which is isolated and selected from the copper sulphide mine in Bor. The main goal of the experiment was to confirm if it is possible to use phosphate ore in combination with examined bacterial culture, as a natural fertilizer. Results obtained show that phosphorus has been leached up to 24,5 % in suspension with At. ferrooxidans, and in the same time, degree of leaching in control suspension (without At. frrooxidans) was up to 7,2 %. Influence of At. ferrooxidans on phosphorus solubilization has been confirmed, so the future perspective of our investigations should be directed to examination of microbiological leaching of apatite mixtures with sulphide substrates, and their potential use in quality improvement of alkaline soils.",

AB  - Ovaj rad ukazuje na moguće pravce upotrebe prirodnih mineralnih sirovina - zeolita, u tehnologijama vezanim za zaštiti i očuvanju životne sredine. Zeoliti su tektoalumosilikati u kojima (Si,Al)4O4 tetraedri izgrađuju kostur ili skelet, stvarajući šupljine u kojima se nalaze veliki katjoni i molekuli vode, koji imaju značajan stepen pokretljivosti što dopušta katjonsku izmenjivost i reverzibilnu dehidrataciju, što je jedno od najvažnijih svojstava zeolita, na kome se i zasniva njegova višestruka primena. Ovi minerali bez prethodne modifikacije se koriste za uklanjanje metala, amonijaka i drugih katjonskih zagađivača iz vode, vazduha i zemljišta. Ispitivanja efikasnosti adsorpcije Pb, Cu, Zn iz otpadnih voda rađena su na prirodnom klinoptilolitu i klinoptilolitu prethodno prevedenom u Na-oblik. Rezultati pokazuju da je visok stepen adsorpcije Pb postignut na oba ispitana mineralna adsorbenta (99%), dok je adsorpcija Cu i Zn efikasnija na Na-klinoptilolitu, i za Cu iznosi 95%, a za Zn 96%. Zeoliti takođe mogu imati značajnu ulogu u uklanjanju amonijum jona iz kontaminiranih voda. Ispitivanja pokazuju da se umanjenje koncentracije amonijum jona kreće od oko 74% do čak 98% u zavisnosti od količine dodatog adsorbenta. U vodama u kojima je prisutan uglavnom amonijačni jon kao zagađivač, zeoliti se nakon upotrebe mogu koristiti za proizvodnju amonijačnih đubriva. Kontrolisanim procesom modifikacije organskim površinski aktivnim supstancama, dobijaju se modifikovani alumosilikatni minerali koji imaju veću efikasnost adsorpcije, kako prema slabije polarnim organskim zagađivačima, tako i prema neorganskim anjonima. Izmenjivi katjoni na površini minerala mogu biti zamenjeni velikim dugolančanim molekulima kvaternarnih amina, pri čemu se dobijaju pogodni adsorbenti za fenol, benzen, ksilen, toluen i druge organske kontaminente. Osim značajne uloge u prečišćavanju voda, u poslednje vreme se dosta govori i o upotrebi zeolita u adsorpciji gasovitih polutanata. Vršena su istraživanja uklanjanje NOx iz industrijskih gasnih tokova upotrebom zeolita aktiviranog amonijumovim jonima. Proces se zasniva na tome da joni amonijuma vezani za mikroporozne alumosilikate redukuju NOx u N2 na temperaturama manjim od 373 K u suvim uslovima. Različiti autori su uporedo ispitivali adsorpciju isparljivih organskih jedinjenja na zeolitu i aktivnom uglju, i istaknuta je prednost zeolita u odnosu na aktivni ugalj u svim aspektima osim u ceni. Na osnovu svega prikazanog, a dat je samo deo širokog spektra moguće primene ovih minerala, može se konstatovati da zeoliti zaista predstavljaju prirodne resurse izuzetnih sposobnosti, i da će dalja ispitivanja njihove upotreba doprineti održivoj budućnosti, s obzirom na trenutnu i projektovanu sliku stanja životne sredine.
AB  - This article points out some possible applications and uses of natural mineral raw materials - zeolites in environmental and remediation technologies. Zeolites are tecto-alumosilicates, in which (Si, Al)4O4 thetraeders form skeleton structures with voids which large cations and water molecules can enter. Within the zeolite structure they remain highly movable which allows cation-exchange and reversible dehydratation. This is one of the main properties of zeolites on which their multiple use is based on. These minerals are often used without any prior modification for removal of metal ions, ammonia and other cationic water, soil and air pollutants. Determinations of adsorption efficiencies for Pb, Cu, Zn from wastewaters were performed with natural clinoptilolite, and modified clinoptilolite in Na-form. Results show high degree of adsorption for Pb on both analyzed mineral adsorbents (99%), while adsorption of Cu and Zn is much more efficient on Na-clinoptilolite and equals 95% for Cu and 96% for Zn. Zeolites can also have significant role in wastewater treatment for ammonia removal processes. Studies show reductions in ammonia concentration (removal efficiency) from 74 to even 98%, depending on quantity of added adsorbent. Furthermore spent adsorbent from treatment processes, where mainly ammonia is present as a pollutant, can be used for production of ammonia fertilizers. Through controlled process of modification with organic surfactants, modified alumosilicate minerals with higher adsorption affinity towards weak polar organic pollutants as well as inorganic anions are obtained. Exchangeable cations on the surface of the mineral can be substituted with large long-chained molecules of quaternary amines and efficient adsorbents for phenol, xylene, toluene, and other organic pollutants are produced. Besides significant role in wastewater treatment processes, lots of potential uses in adsorption of gaseous pollutants are investigated lately. Use of ammonia activated zeolites in NOx removal processes from industrial flue gases, is an example of such research activities. NOx is reduced to N2 on temperatures less than 373 K in dry conditions by the ammonia ions bonded to the microporous alumosilicates. Different authors have analyzed and compared adsorption of volatile organic pollutants on zeolite and charcoal. Results of these studies favor zeolite in all aspects apart from the price. With all mentioned above it is safe to say that zeolites are natural materials with outstanding properties and that further investigations of their use could be beneficial to sustainable future regarding current and projected state of the environment.

AB  - Lithotrophs are involved in many transforming and cyclic reactions of elements in nature, having an important role in biochemical cycles of sulfur and iron, as well of nitrogen and other elements. The term 'lithotroph' is created from the terms 'lithos' (rock) and 'troph' (consumer), meaning the 'eaters of rock. The role of these microorganisms in nature has been widely used by man in processes of metal exploitation. More precise, main goal is converting low-soluble metal compounds, mostly sulfides, into solutions. Practically, naturally occurring reactions have been directed and enhanced, in such a way to get useful metals, mostly from low-grade metal ores and waste materials. The objective of our study was to investigate recovery of useful components from low-grade ores. The microorganism used in leaching was Acidithiobacillus ferrooxidans. Experiments were performed with samples taken from 12 different locations on Bor ore dumps in order to establish recovery conditions. Parameters, like solid-liquid ratio, number of bacteria, rate of leaching, physical and chemical characteristics of ore, rate of watering and number cycles, were determined. The results obtained show 5-fold higher copper leaching efficiency in the suspension with Acidithiobacillus ferrooxidans, then in control suspension. Microbiological leaching of low-grade ores and mine tailings is used nowadays as a method of supplying additional quantities of metal as well as protection of the environment. Natural processes of microbiological leaching, by use of relatively simple technology, are controlled and focused so that uncontrolled loss of useful components (pollutants in this environment) into streams and rivers is stopped.

AB  - Procesi koji se inače spontano dešavaju u prirodi, kada su favorizovani od strane čoveka mogu da ugroze biosferu, i često je neophodno staviti ih pod kontrolu u cilju sprečavanja daljeg zagađivanja. Kada tip rude i geološke karakteristike zemljišta dozvoljavaju, pomoću mikrobioloških lužnih rastvora, moguće je vršiti recikliranje metala sa minimalnim ulaganjima i minimalnim narušavanjem okoline. Sa jedne strane sprečava se kontaminacija podzemnih voda i zemljišta teškim metalima, a sa druge strane vrši se ekstrakcija dragocenih metala iz odlagališta i iz ruda koje imaju nizak sadržaj ovih metala (na primer bakar, zlato, olovo, nikl i cink). Dobijanje ovih metala nekom drugom tehnologijom nije ekonomski isplativo. Danas se značajan broj postrojenja za mikrobiološko luženje, nalazi ne samo u razvijenim zemljama, već zahvaljujući samim karakteristikama ove tehnologije i u zemljama u razvoju. Ovaj rad predstavlja pregled dosadašnjih saznanja u vezi biohidrometalurgije, ali i podsećanje da se ova tehnologija uspešno primenjivala kratko vreme i u našoj zemlji.
AB  - When processes that are spontaneous in nature are accelerated by man, they can endanger biosphere, therefore it is necessary to put them under control to prevent further environmental pollution. By the means of microbial leaching solutions, in the case when the type of ore and the geological characteristics of the soil are suitable, it is possible to recover certain metals with minimum investment and threats to environment. It is usually utilized when conventional mining procedures are too expensive or ineffective in recovering a metal such as copper, gold, lead, nickel and zinc. On the one hand, contamination of ground water and soil by heavy metals is prevented, on the other hand extraction of precious metals from ore dumps and from low-grade ore are occurring. At present, numerous facilities for microbial leaching are in use not only in developed countries, but also in developing countries. This paper presents overview of present achievements in biohydrometallurgy, as well a reminder that this technology was successfully used in our country for short period of time.

abstract = "Procesi koji se inače spontano dešavaju u prirodi, kada su favorizovani od strane čoveka mogu da ugroze biosferu, i često je neophodno staviti ih pod kontrolu u cilju sprečavanja daljeg zagađivanja. Kada tip rude i geološke karakteristike zemljišta dozvoljavaju, pomoću mikrobioloških lužnih rastvora, moguće je vršiti recikliranje metala sa minimalnim ulaganjima i minimalnim narušavanjem okoline. Sa jedne strane sprečava se kontaminacija podzemnih voda i zemljišta teškim metalima, a sa druge strane vrši se ekstrakcija dragocenih metala iz odlagališta i iz ruda koje imaju nizak sadržaj ovih metala (na primer bakar, zlato, olovo, nikl i cink). Dobijanje ovih metala nekom drugom tehnologijom nije ekonomski isplativo. Danas se značajan broj postrojenja za mikrobiološko luženje, nalazi ne samo u razvijenim zemljama, već zahvaljujući samim karakteristikama ove tehnologije i u zemljama u razvoju. Ovaj rad predstavlja pregled dosadašnjih saznanja u vezi biohidrometalurgije, ali i podsećanje da se ova tehnologija uspešno primenjivala kratko vreme i u našoj zemlji., When processes that are spontaneous in nature are accelerated by man, they can endanger biosphere, therefore it is necessary to put them under control to prevent further environmental pollution. By the means of microbial leaching solutions, in the case when the type of ore and the geological characteristics of the soil are suitable, it is possible to recover certain metals with minimum investment and threats to environment. It is usually utilized when conventional mining procedures are too expensive or ineffective in recovering a metal such as copper, gold, lead, nickel and zinc. On the one hand, contamination of ground water and soil by heavy metals is prevented, on the other hand extraction of precious metals from ore dumps and from low-grade ore are occurring. At present, numerous facilities for microbial leaching are in use not only in developed countries, but also in developing countries. This paper presents overview of present achievements in biohydrometallurgy, as well a reminder that this technology was successfully used in our country for short period of time.",

AB  - Mikrobiološko luženje siromašnih ruda i jalovina nalazi danas veliku primenu, kako za dobijanje 'dopunskih' količina metala, tako i u konceptu zaštite životne sredine. Prirodni proces mikrobiološkog luženja, relativno jednostavnom tehnologijom, se stavlja pod kontrolu, usmerava, i na taj način koristi za sprečavanje nekontrolisanog odliva korisnih komponenti u vodotokove (koji u ovoj sredini predstavljaju polutante). Prema svetskim iskustvima, biološki tretman sulfidnih minerala, danas spada u kategoriju konvencionalnih tehnologija za dobijanje zlata i bakra. Takođe, pored ova dva metala, moguća je i ekstrakcija urana, kobalta, nikla i cinka iz polimetaličnih ruda. Ovaj rad predstavlja pregled dosadašnjih saznanja u vezi biodiverziteta acidofilnih mikroorganizama koji su uključeni u oksidaciju sulfidnih minerala, kao i prirode njihovih međusobnih odnosa. Razvojem i usavršavanjem novih tehnika za indentifikaciju mikroorganizama uvećala su se i saznanja o biodiverzitetu mikroorganizama sposobnih da rastu na haldama, odlagalištima i drugim sličnim mestima koja su za čoveka od komercijalne važnosti. Ovakva staništa karakteriše veoma heterogena sredina što utiče na vremensku i prostornu varijabilnost među populacijama mikroorganizama. Prilikom analize mikroflore uočen je iznenađujuće visok biodiverzitet, kao i pojava mikroorganizama iz razdela Firmicutes. Rezultati laboratorijskih eksperimenata u kojima su simulirani uslovi koji vladaju u sistemima kao što su bioreaktori, pokazuju da su mikrobiološki konzorcijumi otporniji i izdržljiviji u odnosu na čiste kulture acidofila. Takođe, i da su mnogo efikasniji u biološkoj oksidaciji ruda i koncentrata. .
AB  - Microbiological leaching of low-grade ores and mine tailings is used nowadays as a method of supplying additional quantities of metal as well as protection of the environment. Natural processes of microbiological leaching, by use of relatively simple technology, are controlled and focused so that uncontrolled loss of useful components (pollutants in this environment) into streams and rivers is stopped. According to the international experience biomining of sulfide minerals is an established global biotechnology for recovering gold and copper. In addition to those two metals it is also possible to extract uranium, cobalt, nickel and zinc from polimetalic ores. This paper presents review of the current knowledge of the biodiversity of the acidofile microorganisms that participate in oxidation of sulfide minerals as well as the nature of their relationships. As the new techniques for identification of microorganisms are discovered and developed the knowledge of the biodiversity of microorganisms capable of growth on dump ores, mine tailings and etc., has increased. This knowledge is of great commercial importance. This type of habitat are characterised by heterogeneous growth environment which influences time and spatial differences in population compositions of the microorganisms. Due to recent research a high biodiversity of those microorganisms was described as well a presence of phylum Firmicutes. The results from the laboratory experiments which have simulated both stirred tank and heap boireactor systems have shown that microbial consortia are more robust than pure cultures of acidophiles, and also tend to be more effective at bioleaching and bio-oxidising ores and concentrates. .
