AB  - Otpadna lignocelulozna biomasa ima izvanredan potencijal kao sirovina za održivu
proizvodnju energije i drugih biomaterijala. Međutim, zbog inferiornih fizičko-hemijskih
svojstava u odnosu na ugalj, biomasa ne predstavlja idealnu sirovinu za industrijsku primenu
i neophodna je njena modifikacija. Hidrotermalna karbonizacija je termo-hemijski postupak
konverzije vlažne otpadne biomase na povišenoj temperature i autogenom pritisku u hidročađ
i procesnu vodu. Dobijena hidročađ, po prirodi slična uglju, može biti primenjena kao
zamena za fosilni ugalj, sekvestraciju ugljenika, adsorbent različitih polutanata, dodatak za
poboljšanje plodnosti zemljišta i dr. Procesna voda, bogata rastvorenim organskim
materijama predstavlja pogodan supstrat za sintezu bitnih hemikalija i proizvodnju biogasa.

AB  - Waste lignocellulosic biomass has outstanding potential as a raw material for sustainable
production of energy and other biomaterials. However, due to inferior physical and chemical
properties in relation to coal, biomass is not an ideal raw material for industrial application,
and its modification is necessary. Hydrothermal carbonization is a thermo-chemical process
for the conversion of wet, waste biomass at elevated temperature and autogenous pressure
into the hydrochar and process water. The obtained coal-like hydrochar, can be applied as a
fossil coal substitute, for carbon sequestration, as an adsorbent for various pollutants, soil
fertility, etc. On the other hand, process water, rich in dissolved organic matter, is a suitable
substrate for synthesis of essential chemicals and the biogas production. This paper provides
an insight into the basic reaction mechanisms, as the most important applications of the

The research in this paper aims at examining the efficiency of two types of mineral raw materials, zeolites and apatites on the immobilization of heavy metals and preventing their inclusion in the food chain. Pb, Cd, Zn and radionuclides (U) were tested. In doses 10 mg kg-1Cd, 500 mg kg-1 Pb, 300 mg kg-1Zn i 300 mg kg-1U. On soil with various physico-chemical properties (sandy chernozem and pseudocley). The efficiency of mineral resources through the adsorption / precipitation of pollutants in the soil was investigated through vegetation experiments with the test culture-plant, Sinapis Alba, through the contents of Pb, Cd, Zn and U in the root and overgrowth mass. The results indicate that both, zeolite and apatite in dosage 20 g kg-1 soils, have contributed to the immobilization of the investigated pollutants, that their effectiveness depends of soils type and their acidity, kinds of pollutant, so their use is justified in the application of technologies for the remediation of contaminated soils in the function of sustainability of agricultural production and the production of healthy food.

AB  - This paper promotes the biometric classification system of plant cultivars, unique characteristics, in terms of the uranium (U) uptake, primarily in the function of the application for phytoremediation. It is known that the degree of adoption of U depends on the plant species and its morphological and physiological properties, but it is less known what impact have plants cultivars, sorts, and hybrids. Therefore, we investigated the U adoption in four cultivars of three plant species (corn, sunflower and soy bean). Vegetation experiments were carried out in a plastic-house filled with soil (0.66 mgU) and with tailing (15.3 mgU kg(-1)) from closed uranium mine Gabrovnica-Kalna southeast of Serbia. Principal Component Analysis (PCA), Cluster Analysis (CA) and analysis of variance (ANOVA) were used for assessing the effect of different substrates cultivars, plant species and plant organs (root or shoot) on U uptake. Obtained results showed that a difference in U uptake by three investigated plant species depends not only of the type of substrate types and plant organs but also of their cultivars. Biometrics techniques provide a good opportunity for a better understanding the behavior of plants and obtaining much more useful information from the original data.

AB  - Cilj ovog rada je ispitivanje mogućnosti upotrebe oklaska kukuruza za uklanjanje teških metala iz vodenih rastvora. Svi biosorpcioni eksperimenti izvođeni su u šaržnom sistemu. Karakterizacija biosorbenta izvršena je termijskom analizom (DTA/TGA), metodom skenirajuće elektronske mikro-skopije i energijsko-disperzivne rendgenske analize (SEM-EDX) i infracrvenom spektroskopijom sa Furijeovom transformacijom (FTIR). Na osnovu FTIR analize oklaska kukuruza pre i nakon uklanjanja Pb2+, Cu2+ i Zn2+ jona, ustanovljeno je da jonska izmena i hemisorpcija učestvuju u procesu biosorpcije jona metala na oklasku kukuruza. Eksperimentalni rezultati obrađeni su Lengmirovim i Frojndlihovim modelom izotermi. Maksimalni adsorpcioni kapacitet oklaska kukuruza za Pb2+, Cu2+ i Zn2+ iznosi 5,59; 2,62 i 1,23 mg/g, respektivno. Nakon ispitivanja procesa desorpcije zaključeno je da se adsorbovani joni metala na oklasku kukuruza efikasno i lako mogu ukloniti rastvorom HNO3. Rezultati ovog istraživanja ukazuju da se oklasak kukuruza može primeniti kao potencijalni biosorbent za uklanjanje Pb2+, Cu2+ i Zn2+ jona iz vodenih rastvora.
AB  - The objective of this study was to investigate corncob as biosorbent for heavy metals removal from aqueous solutions. All biosorption experiments were performed in batch system. The biosorbent were caracterized by thermal analysis (DTA/TGA), Scanning Electron Microscopy and Energy Disperzive X-Ray analysis (SEM-EDX) and Fourier Transform Infrared Spectroscopy (FTIR) analysis. FTIR analysis of corn cob before and after Pb2+, Cu2+ and Zn2+ removal from aqueous solutions showed that ion exchange and chemisorption were involved in biosorption process of metal ions on to corn cob. Experimental data were fitted by Langmuir and Freundlich isotherm models. Maximum adsorption capacity of corn cob for Pb2+, Cu2+ and Zn2+ were 5,59; 2,62 i 1,23 mg/g, respectively. Desorption study showed that metal adsorbed corn cob can be effectively regenerated by HNO3 solution. Results from this study indicated that corn cob can be used as potential biosorbent for Pb2+, Cu2+ and Zn2+ removal from aqueous solutions.

Nakon ispitivanja procesa desorpcije zaključeno je da se adsorbovani joni metala na oklasku kukuruza efikasno i lako mogu ukloniti rastvorom HNO3. Rezultati ovog istraživanja ukazuju da se oklasak kukuruza može primeniti kao potencijalni biosorbent za uklanjanje Pb2+, Cu2+ i Zn2+ jona iz vodenih rastvora., The objective of this study was to investigate corncob as biosorbent for heavy metals removal from aqueous solutions. All biosorption experiments were performed in batch system. The biosorbent were caracterized by thermal analysis (DTA/TGA), Scanning Electron Microscopy and Energy Disperzive X-Ray analysis (SEM-EDX) and Fourier Transform Infrared Spectroscopy (FTIR) analysis. FTIR analysis of corn cob before and after Pb2+, Cu2+ and Zn2+ removal from aqueous solutions showed that ion exchange and chemisorption were involved in biosorption process of metal ions on to corn cob. Experimental data were fitted by Langmuir and Freundlich isotherm models. Maximum adsorption capacity of corn cob for Pb2+, Cu2+ and Zn2+ were 5,59; 2,62 i 1,23 mg/g, respectively. Desorption study showed that metal adsorbed corn cob can be effectively regenerated by HNO3 solution. Results from this study indicated that corn cob can be used as potential biosorbent for Pb2+, Cu2+ and Zn2+ removal from aqueous solutions.",

AB  - The widespread use of depleted uranium (DU) munitions in past wars has
generated a great deal and fear of concern of potential impact on the environment
and human health. During the NATO operations in the former Yugoslavia in
1999.y, Kosovo and Metohia and southern Serbia, were bombed with around 10

AB  - Introduction. Apricots (Prunus armeniaca L.) have an important role in Serbia's fruit production. Average annual production of 25,035 t generates approximately 1,577 t apricot stone (AS) waste and most of it ends up in landfill sites. In order to minimize the environmental impact, an investigation of the possible use of AS was done by developing a biosorbent for wastewater treatment. Materials and methods. AS waste from the fruit processing industry was used to remove Cu(II) ions from water solution by batch adsorption techniques. This solid waste residue was characterized by FTIR, SEM and EDX. The effects of pH, contact time, metal concentration and biosorbent dosage on the process of biosorption were studied. Results and discussion. Obtained FTIR results confirm that the uptake of Cu(II) ions from aqueous solution involves carboxylate moieties from lignin and fatty acids. Also, the presence of seeds in the AS blend significantly increased biosorption performance providing active sites important for the sorption process. The ion exchange mechanism was also confirmed. The best fitting adsorption model is the Langmuir model and the maximum biosorption capacity (qmax) is 4.45mg L-1 at pH 5.0. Biosorption of the Cu(II) ions follows a pseudo second-order kinetic model. According to thermodynamic parameters the biosorption process is endothermic and spontaneous. Conclusion. Numerous biosorbents were investigated for biosorption of Cu(II) ions from aqueous solution, but no report on application of untreated AS waste has been found in literature. This preliminary study confirmed that this material can successfully and rapidly remove dissolved copper ions from dilute solutions.

AB  - Poslednjih decenija se sve više govori o 'new pollutant' - osiromašenom uranijumu (OU), koji se koristi u protivtenkovskim penetratorima zbog svoje velike gustine, prodornosti i pirofornih svojstava.

AB  - Environmental pollution with radionuclides, particularly uranium and its decay products is a serious global problem. The current scientific studies estimated that the contamination originating from TENORM, caused by nuclear and non-nuclear technologies, has significantly increased natural level of radioactivity in the last thirty years. During the last decades all the more were talking about the 'new pollutant' - depleted uranium (DU), which has been used in anti-tank penetrators because of its high density, penetration and pyrophoric properties. It is estimated that during the Gulf War, the war in Bosnia and Yugoslavia and during the invasion of Iraq, 1.4 million missiles with depleted uranium was fired. During the NATO aggression against the ex Yugoslavia in 1999, 112 locations in Kosovo and Metohija, 12 locations in southern Serbia and two locations in Montenegro were bombed. On this occasion, approximately 10 tons of depleted uranium were entered into the environment, mainly on land, where the degree of contamination ranged from 200 to 235000 Bq/kg, which is up to 1000 times higher than the natural level. Fourteen years ago there was very little information about the behavior of ecological systems damaged by DU penetrators fired. Today, unfortunately, we are increasingly faced with the 'invisible threat' of depleted uranium, which has a strong radioactive and hemotoxic impact on human health.

AB  - Hidrotermalna karbonizacija predstavlja postupak prevođenja vlažnog organskog materijala primenom povišene temperature i pritiska u hidročađ, proizvod sličan uglju. Dobijena hidročađ, u zavisnosti od prirode biomase, može biti upotrebljena kao zamena za fosilni ugalj, adsorbent različitih polutanata, dodatak za poboljšanje plodnosti zemljišta i dr. Ovaj rad pruža uvid u osnovne reakcione mehanizme, kao i uticaj procesnih parametara na dobijanje hidročađi. Takođe, istaknut je značaj i prednost postupka hidrotermalne karbonizacije otpadne biomase u odnosu na tradicionalne metode konverzije, kao i aktuelne primene dobijenih proizvoda.
AB  - Hydrothermal carbonization represents a process for converting a wet organic material at elevated temperature and pressure in hydro char, coal-like product. The resulting hydro char, depending on the nature of biomass, can be used as a substitute for fossil coal, adsorbent of various pollutants, soil fertility supplement and others. This paper provides insight into the reaction mechanisms, as well as the influence of process parameters. It also highlighted the importance and advantage of the process of hydrothermal carbonization of biomass compared to traditional methods of conversion, as well as the actual implementation of the product.

AB  - U radu je ispitana mogućnost upotrebe lokalno dostupnih lignoceluloznih materijala kao potencijalnih biosorbenata u svrhu uklanjanja jona bakra iz vodenih rastvora. Ispitivani materijali predstavljaju čvrst otpad koji nastaje nakon prerade kukuruza (oklasak kukuruza) i nakon prerade voća (koštice kajsije). Ovakav otpad ima malu ekonomsku vrednost a njegovo odlaganje predstavlja ekološki problem. U šaržnom sistemu ispitani su uticaj inicijalne koncentracije Cu(II) jona (Ci), količine biomase (m) i zapremine rastvora (V) na efikasnost biosorpcije i vrednost biosorpcionog kapaciteta. Utvrđeni su optimalni procesni parametri. Eksperimentalni rezultati su poređeni sa dva modela: SOP (second order polynomial regression models) i ANN (artificial neural networks), pri čemu je SOP model pokazao prihvatljiv determinacioni koefijent (0,842-0,997), dok je ANN pokazao visoku tačnost prognoze (0,980-0,986) u odnosu na eksperimentalne rezultate.

Using batch adsorption techniques the effects of initial Cu(II) ions concentration (Ci), amount of biomass (m) and volume of metal solution (V) on biosorption efficiency and capacity were studied for both materials, without any pre-treatments. The optimal parameters for both biosorbents were selected depending on the highest sorption capability of biosorbent in removal of Cu(II). Experimental data were compared with second order polynomial regression models (SOPs) and artificial neural networks (ANNs).

AB  - U radu je ispitan uticaj hemijske modifikacije, primenom NaOH, na strukturne promene lignoceluloznog ostatka koštica kajsije (KK) i na adsorpcioni kapacitet biomaterijala prema jonima bakra.

SEM je pokazao da nakon hemijskog tretmana struktura materijala je rapavija kao posledica uklanjanja voska, masti i ostalih nečistoća i pristupačnija molekulima vode i jonima bakra. FTIR analiza je pokazala da pik koji se kod prirodnog materijala javlja na 1735 cm-1 (ukazuje na valencionu vibraciju -C=O veze, koja potiče od karboksilnih grupa ili estra ili voskova i masti) kod modifikovanog materijala je značajno redukovan. Određivanjem tačke nultog potencijala utvrđeno je da je posle modifikacije došlo do promene naelektrisanja površine materijala (pHpzc kod KK je 4,9 a kod KKM je 6,0).

Characterization of natural and alkali treated biomaterial were done by FT-IR and SEM. SEM micrographs showed that the removal of the surface impurities after treatment, improves the surface roughness of KK thus opening more hydroxyl groups and other reactive functional groups on the surface. FT-IR spectrum showed that the peak at 1735 cm-1 from of untreated KK, which is assigned to aromatic carbonyl or carboxyl C=O stretching of carboxylic acids or their esters, was reduced after treatment. After treatment change of point of zero charge value of modified biomaterial was evident: from pHPzc=4.9 (KK) to pHPzc=6.0 (KKM). Overall, the changes made by alkali treatment of KK, resulted in five times higher adsorption capacity.

AB  - In the present study the (bio)sorption efficiency of different materials for the removal of copper ions from aqueous solution has been investigated. Concentration of cooper ions in solutions was 2mmol/l, M/V ration 10 g/l and pH of the solutions were adjusted at 5. Used materials were characterized by scanning electron microscopy. SEM-EDX analyses of some materials indicate that copper binding occurs mainly through ion exchange mechanism, between Cu(II) and exchangeable cations. Removal of copper ions was investigated in the following materials: M. spicatum, peach pits, apricot pits, corn cobs, bentonite, zeolite, apatite, apatite and NH4 modified zeolite and modified zeolite NH4. Best results in copper ions removal showed bentonite and M.spicatum. Therefore, it should examine the possibility of using combined adsorbents. The work is aimed to promote biosorption and adsorption as alternative technologies for wastewater treatment based on the use of economically acceptable biological waste materials and mineral raw materials which are characterized by low cost and high efficiency.

AB  - Jedan od glavnih faktora u procesu biosorpcije predstavlja pH vrednost rastvora sorbata, jer istovremeno utiče na hemijsko ponašanje prisutnih kontaminanata kao i na aktivnost funkcionalnih grupa biosorbenta. U ovom radu ispitan je uticaj pH vrednosti u procesu biosorpcije dvovalentnog bakra, nemodifikovanom otpadnom lignoceluloznom masom koštica breskve (KB). Procenat uklanjanja bakra ovim biosorbentom znatno varira u ispitivanom opsegu pH vrednosti, počev od 2,62% za pH vrednost 2, do 90,43% za pH vrednost 6, pri inicijalnoj koncentraciji bakra od 50 mg/l. Rezultati ispitivanja pokazali su da je za KB pri izabranim operativnim uslovima, proces neophodno voditi na pH 5, što je vrednost nešto viša od vrednosti nultog naelektrisanja (pHpzc) koja iznosi 4,75±0,1. Potvrđena je neophod-nost održavanja pH vrednosti konstantnom za vreme procesa, pri čemu je biosorpcioni kapacitet KB dvostruko veći od biosorpcionog kapaciteta bez održavanja pH vrednosti.
AB  - In the last decade, pollution from anthropogenic sources has reached high levels. Special attention is being paid to heavy metals because of their high toxicity, persistence and bioaccumulation tendency. Since the conventional methods for their removal are either too expensive or create large quantities of toxic sludge, attention has been turning to new technologies such as biosorption, technology that use cheap, abundant, organic waste for sequestering pollutants from contaminated mediums. Among the other factors that affect biosorption process, pH value is one of the most important because it directs both the metal solution chemistry as well as the activity of the biomass functional groups. In this paper, the influence of pH value on biosorption of Cu (II) by unmodified low-cost lignocellulose biosorbent - peach shell (PS) particles, has been studied. The chemical composition of PS, point of zero charge (pHPZC), as well as its surface morphology is also presented. The results showed that this biosorbent contains mainly cellulose and lignin, the components that carry the functional groups responsible for metal binding. Its multilayer surface contains many pores and channels that help diffusion in deeper layers and force biosorption process. Point of zero charge determination was performed with three different KNO3 ionic strengths: 0.1, 0.01 and 0.001 M. The obtained value for pHPZC was 4.75±0.1 and showed that this biosorbent is non-sensitive to the ionic strength of the electrolyte applied. Biosorption experiments were done with peach shell particles of diameters 0.5+0.1 mm at 25°C. The initial copper (II) concentration was 50 mg/dm3 while the biosorbent concentration was 10 g/dm3. Experiments were performed with and without keeping the pH constant. The influence of pH on biosorption process was examined in a pH range of 2-6. The percentage of Cu (II) removed by PS reached its maximum at pH 6, with 90.43% removal, but this percentage can also be attributed to the precipitation of metal at this pH value. However, under the same operational conditions, but at pH 2, the retention of copper was equal to 2.62%. The results also indicate that it is necessary to lead the biosorption process with keeping the pH constant at all times, since the copper removal was about 46% less when the pH value was not kept constant during the biosorption process. The pH value obtained as optimal was slightly higher than the pHPZC value, which indicates that electrostatic attraction is one of the possible binding mechanisms in biosorption process. The results have showed that the removal of Cu (II) with peach shell particles is very sensitive to solution pH and that this parameter should be thoroughly investigated and strongly controlled during the whole removal process.

abstract = "Jedan od glavnih faktora u procesu biosorpcije predstavlja pH vrednost rastvora sorbata, jer istovremeno utiče na hemijsko ponašanje prisutnih kontaminanata kao i na aktivnost funkcionalnih grupa biosorbenta. U ovom radu ispitan je uticaj pH vrednosti u procesu biosorpcije dvovalentnog bakra, nemodifikovanom otpadnom lignoceluloznom masom koštica breskve (KB). Procenat uklanjanja bakra ovim biosorbentom znatno varira u ispitivanom opsegu pH vrednosti, počev od 2,62% za pH vrednost 2, do 90,43% za pH vrednost 6, pri inicijalnoj koncentraciji bakra od 50 mg/l. Rezultati ispitivanja pokazali su da je za KB pri izabranim operativnim uslovima, proces neophodno voditi na pH 5, što je vrednost nešto viša od vrednosti nultog naelektrisanja (pHpzc) koja iznosi 4,75±0,1. Potvrđena je neophod-nost održavanja pH vrednosti konstantnom za vreme procesa, pri čemu je biosorpcioni kapacitet KB dvostruko veći od biosorpcionog kapaciteta bez održavanja pH vrednosti., In the last decade, pollution from anthropogenic sources has reached high levels. Special attention is being paid to heavy metals because of their high toxicity, persistence and bioaccumulation tendency. Since the conventional methods for their removal are either too expensive or create large quantities of toxic sludge, attention has been turning to new technologies such as biosorption, technology that use cheap, abundant, organic waste for sequestering pollutants from contaminated mediums. Among the other factors that affect biosorption process, pH value is one of the most important because it directs both the metal solution chemistry as well as the activity of the biomass functional groups. In this paper, the influence of pH value on biosorption of Cu (II) by unmodified low-cost lignocellulose biosorbent - peach shell (PS) particles, has been studied. The chemical composition of PS, point of zero charge (pHPZC), as well as its surface morphology is also presented. The results showed that this biosorbent contains mainly cellulose and lignin, the components that carry the functional groups responsible for metal binding. Its multilayer surface contains many pores and channels that help diffusion in deeper layers and force biosorption process. Point of zero charge determination was performed with three different KNO3 ionic strengths: 0.1, 0.01 and 0.001 M. The obtained value for pHPZC was 4.75±0.1 and showed that this biosorbent is non-sensitive to the ionic strength of the electrolyte applied. Biosorption experiments were done with peach shell particles of diameters 0.5+0.1 mm at 25°C. The initial copper (II) concentration was 50 mg/dm3 while the biosorbent concentration was 10 g/dm3. Experiments were performed with and without keeping the pH constant. The influence of pH on biosorption process was examined in a pH range of 2-6. The percentage of Cu (II) removed by PS reached its maximum at pH 6, with 90.43% removal, but this percentage can also be attributed to the precipitation of metal at this pH value. However, under the same operational conditions, but at pH 2, the retention of copper was equal to 2.62%. The results also indicate that it is necessary to lead the biosorption process with keeping the pH constant at all times, since the copper removal was about 46% less when the pH value was not kept constant during the biosorption process. The pH value obtained as optimal was slightly higher than the pHPZC value, which indicates that electrostatic attraction is one of the possible binding mechanisms in biosorption process.

Indeks biosorpcije je ispitivan na pH 3.0;6.9 i 7.0 u elektrolitu 0.1 M K2HPO4. Visok indeks biosorpcije aflatoxina B1 (AFL B1) utvrđen je za algu M. spicatum (94,70 odnosno 96,00 %). Nemodifikovane koštice breskve su vezivale manje količine AFL B1 (73.30 odnosno 80.00 %) dok je kod koštice višnje adsorpcija istog mikotoksina bila vidno slabija (58,82 odnosno 41,18%). Vrednosti biosorpcije za ohratoksin A (OTA), imale su, zavisno od biosorbenta i pH, izražena variranja (od 20.00 do 76.20 %).

Ostvareni rezultati ukazuju da su ispitivane otpadne biomase u prirodnom ili modifikovanom obliku bile efikasni biosorbenti pojedinih mikotoksina sa najvećim afinitetom prema AFL B1.
AB  - The paper presents the results of in vitro studies of the possibility of using waste plant materials: biomass of aquatic weed Myriophyllum spicatum (Eurasian watermilfoil or spiked watermilfoil) and fruit stones (peach and sour cherry) in a natural and chemicaly modified form, as a potential biosorbents of different mycotoxins. Biosorption indexes were examined at pH 3.0, 6.9 or 7.0, respectively in electrolite 0.1 M K2HPO4. The highest biosorption indexes of aflatoxin B1 (AFL B1) were determined by algae M. spicatum (94.70 and 96.00%, respectively). Unmodified peach stones binded less quantities of AFL B1 (73.30 and 80.00%, respectively) while sour cherry stones adsorbed the smallest quantity af applied AFL B1 (58.82 and 41.18 %, respectively). The values of biosorption for ochratoxin A (OTA) varied a grait deal, dipending on the biosorbent type and pH values (20.00­76.20%). The best affinity to vomitoxin (DON-in), was observed by unmodifiedpeache stones (50%), at pH 6.9, and for zearalenone (ZON) by M. spicatum (70 and 75%, respectively). Binding of diacetoxyscirp enol (DAS), although much weaker, was recorded at both pH values of applied electrolite by modified peache stones (16.67 and 33.33%, respectively) and modified sour cherry stones (16.67%). Equally good affinity for T-2 toxin was found in modified peache stones, and unmodified and modified form of sour cherriy stones (50.00 and 40.00%, respectively); at lower pH value (3.0) adsorption of this mycotoxin was more pronaunced. Presented results indicate that the tested waste biomasses, in the natural or modified form, were effective biosorbents of different mycotoxins with the highest affinity for AFL B1.

AB  - Metalni implantati za ortopedsku hirurgiju izrađuju se najčešće od nerđajućeg čelika, legura na bazi titana, kobalta ili hroma, koje imaju odlične konstrukcione i mehaničke osobine i otporne su na koroziju.

AB  - Surgical metallic implants are usually made of stainless steel, titanium- and cobalt/chromium- based alloys which have superior structural and mechanical properties, and are corrosion resistant. Nevertheless, they are susceptible to local corrosion in the human body, releasing metal ions into the nearby body tissue and fluids. Keeping the advantage of their mechanical properties, their biocompatibility can be achieved through deposition the bioinert or even bioactive coating onto their surface. Hydroxyapatite is known by its bioactive behavior, originating from its chemical identity with human bones. The electrophoretic deposition is rather old technique used here with a novel nanostructured hydroxyapatite powder to obtain uniform and dense hydroxyapatite coatings, to overcome the restrictions of previously used high temperature coating techniques and to overcome the complex geometry metallic substrate problems. The coating of nanosized hydroxyapatite was electrophoretically deposited on blasted surface of stainless steel 316LVM samples at constant voltage, for different deposition times and subsequently sintered in argon atmosphere at 1000 oC. The HAp powder thermal stability was initially assessed using DTA-TG analyses over the temperature range of 23oC-1000oC. The microstructure characterization of the coating was accomplished using SEM, and phase composition was determined by XRD.

AB  - Conventional treatment technologies for the removal pollutants from the environment usually aren’t economically viable or may further generate huge quantity of toxic chemical sludge which requires further treatment. Biosorption is emerging as a potential alternative technique to the existing conventional technologies; its application is economically acceptable because it reuse biological materials with their major advantages: low cost, high efficiency, renewability, minimization of chemical or biological sludge, easy regeneration of biosorbents and possibility of metal recovery. The paper presents the review of the results of the biosorption efficiency of two biosorbents: peach shell, originating from 'Vino Župa' Company from Aleksandrovac, as agro-industrial waste and urban waste, aquatic plant, Myriophyllum spicatum, harvested from artificial Sava Lake, Belgrade, as low cost biosorbents for removal of several pollution type: heavy metal ions (Cu, Pb), uranium as radionuclide and mycotoxins. Biosorption treatment method is especially applicable in developing countries where a 'low cost tech' approach may be a suitable option.

AB  - The rapid increase in global industrial activities has lead to the serious environmental pollution that requires systematic and sustainable approach in order to protect environment and biodiversity. Special concern is accented on heavy metal pollution because of their high toxicity, persistence and bioaccumulation tendency. The conventional methods for their removing are often either too expensive or create a large quantities of toxic sludge, so the other technologies, cheaper and more effective should be employed. Biosorption is one of the recently employed promising technologies that use biomaterials as sorbents for different type of pollution. Thanks to their active surface groups, biosorbents pose wider operational spectrum than mono functional ion exchangers. Agricultural waste materials have proved to be highly efficient, low cost and renewable source of biomass that can be exploited for heavy metal remediation, which leads to increase of their life cycle and also solve their disposal problem. The purpose of this paper is investigation of possible application of wasted untreated biomass from 'Vino Župa' Company as potential biosorbent that can be used for copper removal from water solutions. For this purpose, several type of biomass have been examined and the preliminary results presented in this paper have showed that this wasted untreated materials can bee used as promising and cheap adsorbents for copper removal from water solutions, but also that further physical and chemical modifications should be done in order to increase their biosorption capacity.
