AB  - Selo Dubravica se delimično nalazi iznad zapadnog lignitskog ležišta Kostolačkog basena. Ispitivanjem suvog ostatka dobijenog iz vode za piće iz dva individualna bunara rendgenskom difrakcionom analizom, na osnovu karakterističnih pikova, utvrđeno je prisustvo urana u vodi za piće. Indirektnom metodom Rajkovića i saradnika pouzdano je dokazano da je u prvom uzorku koncentracija urana u vodi za piće za 85,8% viša (3,71 mg/L), dok je u drugom uzorku koncentracija urana svega 22% niža (1.56 mg/L) od vrednosti MDK predviđene Pravilnikom (2 mg/L). Analiza posledica unošenja urana u čovekov organizam ukazala je na to da se na ovaj način unosi 0,84-2 mg urana u čovekov organizam na godišnjem nivou, odnosno 0,09-0,22 mg deponuje na godišnjem nivou u bubreg. Procena potencijalnog zdravstvenog rizika usled prisustva urana u vodi za piće ukazala je na to da je stanovništvo koje koristi vodu za piće iz prvog bunara i u kratkom vremenskom intervalu ugroženo od urana. Što se tiče dugoročnog rizika, proračun je ukazao da su u slučaju prvog uzorka vode za piće ugroženo oko 25, a u slučaju drugog uzorka vode za piće 10 stanovnika od 1000 stanovnika. Kako je bubreg organ u kome se uran deponuje u najvećoj meri u čovekovom organizmu, a dejstvo urana dugotrajno, slabljenje i otkazivanje funkcije bubrega može biti toliko da je čak 75% funkcije bubrega uništeno da bi se pokazali prvi klinički simptomi. Ova pojava se zapaža među stanovništvom duž reka Kolubare, Drine, Save i Morave i naziva se endemska nefropatija. Kao mogući uzročnici ističu se elementi koji se nalaze u tragovima (Pb, Cd, Si), živi agensi (bakterije i virusi), gljivični i biljni toksini, genetski faktori i imuni mehanizam, ali ne i uran u vodi za piće. Ispitivanja izvršena u ovom radu jasno ukazuju i na ulogu urana u epidemiji endemske nefropatije koja je u porastu i koja nema akutnu fazu već bolest progredira ka bubrežnoj insuficijenciji i terminalnom stadijumu bolesti bubrega. Zvanični podaci koji govore o porastu endemske nefropatije i šećerne bolesti i porastu njihovog udela u bolestima, kao i stope opšteg mortaliteta koja iznosi 18,19%, nedvosmisleno ukazuju na to da se uloga urana u životnoj sredini Braničevskog okruga ni na koji način ne sme zanemarivati.

AB  - The village of Dubravica is partially located over the western lignite deposits of the Kostolac basin. The examination of the dry residue obtained from drinking water from two individual wells by X-ray diffraction analysis, based on a typical peak, showed the presence of uranium in drinking water. The indirect method by Rajković and associates showed that, in sample I, the concentration of uranium in drinking water was 85.5 percent higher (3.71 mg/L) and that the concentration of uranium in sample II was only 22 percent lower (1.56 mg/L) than the Maximum Allowable Concentration (MAC) values required by the Regulations (2 mg/L). Analysis of the result of the introduction of uranium in the human body has shown that this way brings 0.84 to 2 mg of uranium in the human organism per annum or 0.09 to 0.22 mg of uranium is deposited annually in the kidney. Assessment of the potential health risk due to the presence of uranium in drinking water indicated that the population using drinking water from wells will be threatened by uranium in a short time interval. Regarding the long-term risk, the calculation has indicated that in the first sample of drinking water, about 25 inhabitants, and in the case of the second sample of drinking water, 10 inhabitants out of 1000 inhabitants are endangered. As the kidney is the organ in which uranium is deposited (accumulated) to the greatest extent, its presence causes weakening and failure of kidney function, which can destroy 75 percent of kidney function until the manifestation of the first clinical symptoms. This phenomenon is observed among the population along the rivers the Kolubara, the Drina, the Sava and the Morava and is called endemic nephropathy. The elements found in trace amounts (Pb, Cd, Si), live agents (bacteria and viruses), fungal plant toxins, genetic factors and immune mechanism can be listed as possible causes. However, uranium in drinking water has not been listed so far. The tests performed in this study clearly show the role of uranium in the epidemic, endemic nephropathy, which is growing and which is not at the acute phase of the disease but has already progressed to renal failure and end-stage kidney disease. Official data on the rise of endemic nephropathy and diabetes and increasing their share in diseases, as well as overall mortality rates, which amount to 18.19%, clearly indicate that the role of uranium in the Braničevo district environment should not be ignored. Since there are settlements on the terrain to be investigated, uranium and its migration through the environment must be monitored as all conditions for its migration are unfortunately favourable.

AB  - In this paper, the character of structural changes induced by different mechanical treatments to Prunus persica stones (PSs), and its subsequent effect on biosorption kinetics of Cu(II) were investigated. PSs were processed in vibratory disk mill (PS-V) and ultra-centrifugal mill (PS-C) and characterized by XRD, BET, SEM and FTIR spectroscopy. It was shown that PS-V was smaller and more reactive with less crystallinity index and hydrogen bond intensity compared to PS-C. In opposite, surface area of the PS-C was bigger than that of the PS-V. The total pore volume was about threefold, while the volume of micro pores was 9.29 times higher in PS-Cs than in PS-Vs. The kinetics of Cu(II) biosorption by both PSs was tested through various kinetic models: pseudo-first and pseudo-second order rate equations, Elovich equation, Boyd model, Weber-Morris and Urano-Tachikawa intraparticle diffusion model. For both sample types, Cu(II) biosorption occurred through combination of intraparticle and film diffusion mechanism, while kinetic results were best described by the pseudo-second order kinetic model. At the same time, the results indicated that together with kinetic rate the biosorption capacity of PS-C (21.20 mg g(-1)) was higher than that of PS-V (16.30 mg g(-1)). Mechanical activation like crushing and grinding will change material particle size, specific surface area and porosity, as well as its crystallinity. However, this paper elucidates that such physical structural changes will impact on heavy metal ions removal efficiency. This investigation suggests that the type of size reduction in lignocellulosic biosorbent preparation plays a very important role in overall biosorption performance, so it should be carefully considered every time when the mechanical treatment of material is necessary to be applied.

AB  - A new biosorbent - alginate encapsulated with Myriophyllum spicatum - MsA was investigated for lead ions removal. This biosorbent was characterized by scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FT-IR), zeta potential, X ray Diffraction (XRD) and size distribution analysis. FT-IR analysis demonstrated that the lead ions sequestration mechanism included ion exchange and lead complexation with the carboxyl, carbonyl and hydroxyl groups in MsA. In order to better understand the mechanisms of the binding of Pb(II) on immobilized M. spicatum beads, 3 reaction and one diffusion based kinetic models were applied on kinetic data removal lead ions on three materials: M. spicatum, Ca-alginate and MsA. Myriophyllum spicatum encapsulated with alginate - MsA have higher adsorption capacity than M. spicatum. Among examined six isotherms Redlich-Peterson and the Langmuir isotherm model exhibited the best fit to the experimental data, with capacities ranging from 230 to 268.7 mg/g. Among the various tested desorption agents, nitric acid has proven to be the best. The obtained results suggest that the immobilized M. spicatum biosorbent holds great potential for lead wastewater treatment applications.

AB  - In recent years, a technique for conversion of waste biomass into solid carbon material (hydrochar) with high energy potential, become very attractive. This process is known as hidrothermal carbonization (HTC). The conversion of raw biomass into the hydrochars is called "wet" pyrolysis since conversion take place at moderate 1 temperatures and pressures, while subcritical water is used as the process medium. Major influences on the structure of the obtained product have different process parameters such as pressure, temperature, reaction time, biomass type and biomass and water ratio. Based on the literature review, it can be concluded that the temperature has the greatest influence on the structural changes of the obtained hydrochars and therefore stands out as the most important parameter of the HTC process. It has been shown that increasing of reaction temperature increases the degradation of biomass, thus the yield, ash and volatile content in the resulting hydrochars is reduced. On the other hand, the carbon content, fuel properties and energy density are increased. This suggests that temperature variation during the HTC process provides hydrochars with improved fuel characteristics in relation to the feedstock, whereby the utilization value of waste biomass was significantly improved. This is the first report of HTC conversion of waste substrates for mushrooms cultivation and comparison of obtained results with literature data.

AB  - It is of great importance to treat wastewaters, which contain heavy metals in concentrations harmful to the environment, before their discharge into watercourses. The biosorption is powerful tool for the removal of heavy metals from wastewaters. Paulownia leaves become biowaste during wood processing in industry and represent possible biosorbent or source for production of efficient adsorbents. In this study, Paulownia leaves and Paulownia leaves hydrochar produced at 180 °C were used as adsorbents of Pb2+ ions and their efficiency was determined. Paulownia leaves and hydrochar, before and after adsorption of Pb2+ ions, were characterized by FTIR spectroscopy. It was observed that oxygen functional groups might were crucial for adsorption of Pb2+ ions. The preliminary adsorption test showed that leaves without structural changes had better adsorption capacity which was q=34.53 mg/g than hydrochar produced at 180°C, q=10.57 mg/g. Therefore, Paulownia leaves could be considered as efficient adsorbent for Pb2+ removal.

AB  - Hydrochar prepared from the hydrothermal carbonization of the grape pomace was investigated as potential adsorbent for the Cd from aqueous solution. To increase the sorption efficiency, the hydrochar was modified using the different chemical treatments (citric acid (CA), H2O, and KOH) and characterized by a FTIR spectroscopy. The preliminary adsorption tests showed that the adsorption capacity of hydrochars was 3.8 before and 5.0, 14.5 and 49.34 mg/g upon modification by CA, HO and KOH, respectively. It was observed that the KOH activation enhances the surface functionality of the hydrochar, and thus significantly improves the Cd adsorption capacity. Therefore, the KOH-modified hydrochar should be considered as an efficient adsorbent for Cd removal.

AB  - Locally available apricot (Prunus armeniaca L.) shells classified as a waste product from fruit processing, were alkali activated in order to develop an efficient heavy metal ions sorbent for water purification. To examine the changes occurred after alkali treatment, raw (SH) and modified apricot shells (SHM) were thoroughly characterized in terms of their chemical composition and surface properties. Chemical analysis revealed that alkaline treatment causes the disintegration of hemicellulose (its content decreased from 19.2 to 3.5%), which was in accordance with FTIR results. SEM micrographs and the mercury intrusion porosimetry revealed a larger surface area and porosity of SHM. Bohem's acid-base titration method indicated that the most of the SHM surface carboxylic groups were in sodium salt form and together with the pH of points of zero charge showed increase of surface alkalinity after modification. Treatment with NaOH enhanced the adsorption capacity by 154, 61 and 90% for Cu2+, Zn2+ and Pb2+, respectively. The amount of cations released from SHM was almost equal to the amount of adsorbed metal ions, suggesting ion exchange mechanism. The pseudo-second order kinetic indicated that the heavy metals cations were bound predominantly by complexation. In order to establish the effectiveness of the biosorbent in real wastewater sample, SHM was employed for cleaning-up of drain water emanating from atomic adsorption spectrophotometer. The SHM showed high removal efficiency towards multiple metal ions. The amounts of Fe, Pb, Cu and Cr ions were reduced by 97, 87, 81 and 80%, respectively, while Ni and Zn amounts were reduced for 33 and 14%. Used biosorbent SHM can be successfully regenerated with HCl (desorption > 95%) and after regeneration biosorbent can be reused or it can be safely disposed.

AB  - The preliminary assessment of the properties of alginate immobilized aquatic weed Myriophyllum spicatum beads-MsAlg in a multi-element system of nine Serbian lakes water samples was done. Herein, the results obtained in the biosorption experiment with MsAlg contents of twenty-two elements analysed by inductively coupled plasma-optical emission spectrometry, biosorption capacity, element removal efficiency, total hardness (TH) and quality index of water (WQI) are presented. Scanning electron microscopy with energy dispersive X-ray spectroscopy was used for the characterization of M. spicatum and its beads. The study showed that aluminium, magnesium and strontium were adsorbed by MsAlg in the water samples from all examined lakes; barium and iron in the water samples from six lakes. The overall average efficiency of MsAlg in biosorption of elements was in the following order: Al > Ba > Sr > Fe > Mg (58.6, 51.7, 48.2, 23.9 and 17.7%, respectively). The increase of TH and WQI values after the biosorption was noticed in all studied lake water samples. The most significant correlations for pH were regarding the contents of B, Mg and Ca, whereas WQI was highly correlated to the contents of B and Mg, and pH. The complexity of the obtained data was explained by Cluster Analysis and Principal Component Analysis, which showed good discrimination capabilities between the water samples taken from different locations. Considering that the invasive M. spicatum is natural, widespread and that its immobilization is cheap and eco-friendly, presented findings could be helpful in further assessment of MsAlg beads for its potential use as biofilter.

AB  - In this study, hydrothermal carbonization (HTC) was employed for thermochemical conversion of energy crop Miscanthus x gigcuiteus GREEF et DEU. The effect of process temperatures, in the range between 180 and 220 degrees C, on the relevant characteristics of the obtained products, hydrochars and process waters, was investigated. The obtained results showed that the HTC promotes fuel properties and energy density of the solids regarding the feedstock. Furthermore, temperature governs the lowering of the volatiles, ash, and moisture in hydrochars, making its potential use as solid fuels more beneficial than the miscanthus. FT-IR spectroscopy and thermal analysis confirmed degradation of hemicellulose at temperatures above 200 degrees C, and an increase of the total content of cellulose and lignin in the hydrochars. In general, hydrochar obtained at 220 degrees C exhibited the best combustion characteristics and is, therefore, the most suitable for use as a solid biofuel. However, in the residual liquids, some amounts of fluorene, phenanthrene, fluoranthene, and pyrene were detected. The polluting potential, visible through the growth of TOC, COD and BOD values, of the analyzed process waters, increases with the rise in carbonization temperature. The TOC values (5.8-9.9 gC L-1) were on average lower than those reported for organic wastewaters (> 10 gC L-1). The proportion of hydrocarbons in the process water increases with the increase in the carbonization temperature from 2.92 to 20.9%. Consequently, bioassays with Vibrio fischeri showed a relatively high toxicity of the liquid phase, where a concentration of about 1% was causing bacteria inhibition of 50%.

abstract = "In this study, hydrothermal carbonization (HTC) was employed for thermochemical conversion of energy crop Miscanthus x gigcuiteus GREEF et DEU. The effect of process temperatures, in the range between 180 and 220 degrees C, on the relevant characteristics of the obtained products, hydrochars and process waters, was investigated. The obtained results showed that the HTC promotes fuel properties and energy density of the solids regarding the feedstock. Furthermore, temperature governs the lowering of the volatiles, ash, and moisture in hydrochars, making its potential use as solid fuels more beneficial than the miscanthus. FT-IR spectroscopy and thermal analysis confirmed degradation of hemicellulose at temperatures above 200 degrees C, and an increase of the total content of cellulose and lignin in the hydrochars. In general, hydrochar obtained at 220 degrees C exhibited the best combustion characteristics and is, therefore, the most suitable for use as a solid biofuel. However, in the residual liquids, some amounts of fluorene, phenanthrene, fluoranthene, and pyrene were detected. The polluting potential, visible through the growth of TOC, COD and BOD values, of the analyzed process waters, increases with the rise in carbonization temperature. The TOC values (5.8-9.9 gC L-1) were on average lower than those reported for organic wastewaters (> 10 gC L-1). The proportion of hydrocarbons in the process water increases with the increase in the carbonization temperature from 2.92 to 20.9%. Consequently, bioassays with Vibrio fischeri showed a relatively high toxicity of the liquid phase, where a concentration of about 1% was causing bacteria inhibition of 50%.",

AB  - This paper presents an eco-friendly approach for minimizing heavy metal pollution, offering food waste valorization and energy source at the same time. It focuses on Cu(II) sorption by low cost sorbent developed by mechanical treatment of Prunus persica L. stones, a food industry waste biomass. Removal of Cu(II) was studied at different operating parameters in a batch sorption system, with special attention on temperature effect on sorption process. The pseudo-first order, pseudo-second order and Elovich model were applied to test kinetic experimental data. Equilibrium experimental results were fitted to Langmuir, Freundlich, Sips, Toth and Dubinin-Radushkevich isotherms to elucidate the type and sorption performance. Characteristic functional groups responsible for Cu(II) binding and thermal behavior of PS have been investigated using FT-IR and TGA analyses. The activation parameters were calculated using Arrhenius and Eyring equations. Using equilibrium data at different temperatures, thermodynamic parameters Delta G degrees, Delta H degrees and Delta S degrees were calculated, suggesting that the sorption of Cu(II) on PS is spontaneous and endothermic process with increased randomness during the sorption. The isosteric heat of adsorption (Delta H-iso) was determined, suggesting the non -uniformity of PS surface and lateral interactions among ions sorbed. Desorption experiments performed with different chemicals have confirmed the reusability of PS for five cycles, without losing and even improving its sorption capacity. Results presented in this paper might help in appropriate design of purification systems using this type of lignocellulosic waste.

AB  - Antropogeni faktor uslovio je sve veće prisustvo fluoridnih jona u podzemnim vodama. Sa druge strane, povećana svest o štetnosti visokih koncentracija ovog polutanta u pijaćoj vodi, dovela je do strožijih standarda kada su ovi joni u pitanju. Zato se poslednje decenije vrše intenzivna ispitivanja novih metoda za uklanjanje fluoridnih jona iz otpadnih i pijaćih voda. U ovom radu je ispitana mogućnost upotrebe aluminijum alginatnih čestica, jeftinog i efikasnog adsorbenta, za uklanjanje fluoridnih jona. Detaljna karakterizacija primenjenog adsorbenta urađena je pre i nakon adsorpcije primenom FT-IR tehnike. Eksperimenti su izvedeni u šaržnom sistemu sa mešanjem, pri različitim polaznim koncentracijama adsorbenta i adsorbata. Dobijen rezultat od 11,40 mg F-/g Al-alginata ukazuje na visok kapacitet adsorbenta, a kinetički parametri pokazuju brzu kinetiku uklanjanja ispitivanog polutanta.
AB  - Fluoride ions are increasingly present in the groundwater mainly due to the anthropogenic activity. On the other hand, increased awareness of harmful effects caused by high concentrations of F-in drinking water, leads to severe standards of water quality. Because of this, intensive researches of new methods for fluoride removal from water streams have been made in last decade. This paper examines the potential of aluminum alginate particles as a cheap and efficient biosorbent for F- removal. The adsorbent characterization before and after F- adsorption was performed using FT-IR technique. Adsorption experiments were conducted in a stirring batch mode, varying both concentration of adsorbate and adsorbent dose. Obtained result of 11,40 mg F-/g Al-alginate indicates a high adsorption capacity, while the kinetic parameters show fast removal kinetics.

AB  - In this study the novel biosorbent - raw corn silk (CS) was investigated for Cu2+ and Zn2+ removal from aqueous solutions. The physical and chemical properties of CS were determined by SEM - EDX and ATR - FTIR techniques. The SEM micrographs revealed that surface morphology of CS is suitable for metal adsorption, while FTIR analysis confirmed presence of various active groups (O-H, C-O, C-O C, C=C and amide II) which could interact with metal ions. The adsorption experiments were performed in batch system. Experimental data were fitted by pseudo - first order and pseudo - second order kinetic models as well as Langmuir and Freundlich isotherm models. Biosorption of the both metals follow pseudo second order kinetic model. The best fitting adsorption model is Langmuir model and the maximum biosorption capacities (q(max)) for Cu2+ and Zn2+ at 313 K and pH 5.0 were 15.35 mg g(-1) and 13.98 mg g(-1), respectively. The thermodynamic parameters such as Gibbs free energy change (Delta G), enthalpy change (Delta H) and entropy change (Delta S) were studied at different metal concentration and three temperatures. According to thermodynamic study, the biosorption process for both metals is feasible, endothermic and spontaneous. According to thermodynamic study, the biosorption process for both metals is feasible, endothermic and spontaneous. Ion - exchange is the dominant mechanism in adsorption of Cu2+ and Zn2+ on the CS with a certain degree of complexation. Desorption study was performed in three adsorption/desorption cycles with diluted nitric acid. Results show that after metal adsorption CS can be efficiently recovered and reused for new adsorption process. Obtained results indicated that corn silk could be used as efficient novel biosorbent for Cu2+ and Zn2+ removal from water samples.

AB  - The most important source of renewable energy in Serbia represents biomass (60.3 %) with total potential of 3.405 million toe. Almost half of this amount (1.67 million toe) represents agricultural and industrial waste, with further negligible revalorization. Various investigations have demonstrated that agricultural byproducts have promising capacities to remove a variety of pollutants, which might increase the sustainability of their life cycle. This paper investigates the possible use of lignocellulosic waste material (LCW), originating from food industry as biosorbent for heavy metals, and later as a solid fuel. For this purpose we have used peach stone particles (PS) obtained by mechanical activation of this LCW as Cu(II) sorbent. The physical and chemical characteristics of PS reveal its complex structure which was confirmed by SEM, and FTIR analysis. PS behavior on pyrolysis process was studied by dynamic thermo gravimetric and derivate thermo gravimetric analysis. Results show that this lignocellulosic waste can be applied as sorbent and as a fuel. This approve that this agricultural waste can be a resource more than a waste and that it does not need to be disposed of in the costly and inefficient way, which is especially important in developing economies, like Serbian.

PS behavior on pyrolysis process was studied by dynamic thermo gravimetric and derivate thermo gravimetric analysis. Results show that this lignocellulosic waste can be applied as sorbent and as a fuel. This approve that this agricultural waste can be a resource more than a waste and that it does not need to be disposed of in the costly and inefficient way, which is especially important in developing economies, like Serbian.",

AB  - In order to obtain effective mineral fertilizer, different mixtures of phosphate rock (PR) with natural clinoptilolite (Cp) and NH4+ saturated clinoptilolite (NH4-Cp) were subjected to soft mechanical activation. Mean concentrations of P released from mechanically activated (MA) substrates, MACp/PR and MANH(4)-Cp/PR, ranged between 281-3.19 mg L-1 and 202-774 mg L-1, respectively. These are 10 to 15 times higher P concentrations than those released from the corresponding non-activated mixtures. Solution Ca2+, K+, Na+ and Mg2+ concentrations varied according to the composition of the mixtures and the contact time between the two minerals within their optimal values required for plant growth. The obtained results suggest that the efficiency of the NH4-Cp/PR mixtures can be significantly increased by the proposed mechanical activation. Influence of process parameters on the observed concentrations of nutrients was shown using multivariate statistics. The highest fertilization potential demonstrated MANH(4)-Cp/PR mixture with the largest NH4-Cp share and the longest proposed mixing time.

AB  - Protection and improvement of the environment, especially preservation and protection of the land, has become one of the most important problems of the modern world today. 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.

Polazni i modifikovani zeoliti su okarakterisani hemijskom analizom, skenirajućom elektronskom mikroskopijom (SEM), rendgenskom analizom (XRPD), IC spektroskopijom, termičkom (TG/DTA) analizom i određivanjem kapaciteta katjonske izmene, a polazne i neadsorbovane količine uranijum jona su određene fluorimetrijski. Eksperimenti su sprovedeni da se ispita uticaj odnosa čvrsto/tečno, pH i vremena na adsorpciju uranijum jona na zeolitu. Utvrđeno je da tretman sa kiselinama zeolita povećava adsorpciju uranijum jona. Najviši indeks adsorpcije imao je uzorak zeolita modifikovan sa hlorovodoničnom kiselinom.

AB  - The objective of this study was the review of natural zeolite, modified with acid, as a candidate material for the remediation of groundwater contaminated by uranium(VI). The modified zeolite samples were obtained by treatment of natural zeolite - clinoptilolite with acids: hydrochloric, oxalyc and citric. Starting and modified zeolites were characterized by chemical analysis, SEM, XRPD analysis, IR spectroscopy, thermal (TG/DT) analysis and by determination of cation exchange capacity, while starting and nonadsorbed amounts of uranium(VI) ion were determined by fluorometric method. Batch experiments were conducted to investigate the effect of solid/liquid ratio, pH and time on the U(VI) uptake by zeolite. Modification of zeolitic tuff with acids significantly increased adsorption of uranium(VI). The highest adsorption of uranium(VI) ion was achieved on clinoptilolite modified with hydrochloric acid. Uranium(VI) adsorption data for zeolite modified with hydrochloric acid was fitted to the Langmuir model.

AB  - Hydrothermal carbonization is a promising route for conversion of lignocellulosic biomass into biofuels, adsorbents and specific chemicals. Herein, the evaluation of grape pomace as a precursor to obtain hydrochar, an adsorbent of copper from wastewaters, using hydrothermal conversion was performed. By examining the effect of sorbent dose and contact time, the ability of grape pomace hydrochar to effectively remove copper from aqueous solutions was confirmed. The obtained adsorption isotherms were best described by the Langmuir model. FTIR analysis of samples before and after adsorption supports the proposed mechanism of metal binding onto hydrochar surface.

AB  - In this work, corn cob and corn silk were used as biosorbent for removal of Pb2+, Cu2+ and Zn2+ ions
from aqueous solutions. Adsorption experiments were performed in batch mode. Corn cob and corn silk were
characterized by scanning electron microscopy (SEM). The maximum biosorption capacities of corn cob was
found to be 0.049, 0.053 and 0.021 mmol L-1 for Pb2+, Cu2+ and Zn2+ ions, respectively. At the other hand,
higher values of maximum biosorption capacities: 0.40, 0.22 and 0.19 mmol L-1 for Pb2+, Cu2+ and Zn2+ ions,
respectively, indicates that corn silk has better adsorption characteristics in comparison to corn cob.

AB  - Maintaining of good quality of groundwater is of great public interest worldwide.
However, this source is highly vulnerable to different pollution sources such as
industry, mining, irrigation, and so on. The pollution problems are more often
observed in Karst areas where large amounts of fresh water can be contaminated in a
short time. The application of an in situ technique for remediation of contaminated
groundwater is highly recommended due to its simplicity of performance and
economic benefit. Among in situ techniques, the permeable reactive barrier is the
most attractive method as it allows for using different materials in the barrier for
remediation of contaminated groundwater. Materials for PBR must demonstrate
good contaminant binding properties, the ability of their retention, excellent
hydraulic properties, satisfactory mechanical properties for safe performance, and
ensure a smooth flow through the barrier without disturbing the natural flow.
Nowadays the research is focused on investigation of different natural materials to
protect the environment, due to their low cost and availability in nature in large
quantities. The purpose of this work is to investigate the efficacy of various natural
materials such as natural and iron-modified zeolite, apatite, concentrated apatite,
kaolin and raw bentonite to remove heavy metals (lead and cadmium) from
contaminated groundwater using the in situ PBR. The batch test involves sorption
experiments followed by leaching experiments. In sorption experiments, the
amounts of metal removal by different sorbents were evaluated for cadmium and
lead from simulated wastewater with similar initial metal concentrations. The
leaching experiment included evaluation of metal retained by the saturated sorbents
in ultrapure water with adjusted pH values at 2.98 and 6.07. Additionally, pH values
of solutions were recorded during both experiments. Based on obtained results, the
sorbents that provide the optimal metal removal and their retaining from the
contaminated groundwater were selected.

AB  - In this study, carbonization products of grape pomace (hydrochar and process water) have been thoroughly characterized in order to assess its fuel properties, physico-chemical composition and to optimize its production. The obtained detailed insight into transformations of the biomass during hydrothermal conversion between 180-220 degrees C revealed that the hydrochar obtained at 220 degrees C exhibits a considerable energetic potential, increased porosity and re-adsorption abbility. Hydrothermally induced structural changes in the obtained hydrochars were unveiled by thermal and morphology analysis, FTIR and NIR spectroscopy. Temperature increment caused a decrease in antioxidative capacity, anthocyanin and organic acid content in process water and simultaneous increase in total phenolic and individual organic components content. The overall effect of the reaction temperature on products characteristics was assessed by multivariate data analysis. Obtained results substantiated the suitability of hydrothermal conversion of grape pomace into highly valuable fuels and versatile products.

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  - There is no data about the corn silk usage as adsorbent for lead removal. In the present study, the corn silk (CS), without any modification, was investigated for adsorption of Pb2+ ions from aqueous solutions. The CS before and after Pb2+ adsorption was characterized by SEM-EDX and ATR-FTIR. The effect of pH, contact time, CS dosage and initial metal concentration on process of adsorption was investigated using batch adsorption procedure. The experimental data were fitted to Langmuir and Freundlich isotherm models, and the best data fit was achieved with the Freundlich isotherm model. Also the Langmuir and Freundlich isotherm models constants R-L and n suggesting favorable adsorption of Pb2+ on the CS. Not only the ion -exchange mechanism was confirmed as an adsorption mechanism but the complexation process has also been verified according to results from ATR-FTIR spectra. Thermodynamic parameters were investigated too. Based on desorption study result, the adsorbent can be efficiently recovered. The present investigation qualified the corn silk (Zea mays L.) as a possible good adsorbent of lead from aqueous solutions.
