AB  - Uvod: Kofein je prirodni alkaloid, izolovan iz više od 60 biljnih vrsta. Preko 80 % svetske populacije
svakodnevno unosi kofein u organizam kroz konzumaciju kafe, čajeva, čokolade i, u poslednje
vreme, energetskih pića. Ne treba zanemariti činjenicu da kofein, kao farmakološki aktivna
supstanca, ulazi u sastav mnogih lekova koji se na tržištu Republike Srbije izdaju bez lekarskog
recepta. Sem toga, kofein je psihoaktivni stimulans, blag je diuretik i pokazuje interakciju sa nekim
lekovima usled indukcije CYP1 i CYP2 izoenzima, zbog čega je potrebno voditi računa o količini
koja se unese u organizam. U skladu s tim, važno je i da sadržaj kofeina u energetskim pićima odgovara
podacima koje proizvođači navode na deklaraciji.
Cilj: Cilj ovog rada bio je spektrofotometrijsko određivanje sadržaja kofeina u uzorcima energetskih
pića i čajeva proizvođača dostupnih na tržištu R. Srbije.
Materijal i metode: Kofein je određivan metodom ultraljubičaste i vidljive (UV/VIS) spektrofotometrije
u devet vrsta energetskih pića i po četiri uzorka crnog i zelenog čaja.
Rezultati: U uzorcima energetskih pića određeni sadržaj kofeina je u opsegu od 26,81 do 35,44
mg/100 mL i u skladu je s deklarisanim sadržajem. Sadržaj kofeina u uzorcima čajeva varira u
odnosu na vrstu (11,27-22,61 mg/100 mL zeleni i 13,85-22,73 mg/100 mL crni), ali je vezan i za
poreklo, uslove gajenja i proces prerade čajeva.
Zaključak: Ultraljubičasta i vidljiva spektrofotometrija se pokazala kao brza, precizna i jednostavna
metoda za određivanje kofeina u energetskim pićima i čajevima. Imajući u vidu dobijene rezultate,
važno je istaći da unos kofeina kroz uobičajenu dnevnu konzumaciju čajeva i energetskih pića
ne bi trebalo da utiče negativno na zdravlje ljudi. Svakako treba imati u vidu da se ovaj alkaloid
dodatno može uneti i putem drugih izvora, što je posebno važno za određene grupe pacijenata.
AB  - Introduction: Caffeine is a natural alkaloid, isolated from more than 60 plant species. Over 80%  of  the  world’s  population  consumes  caffeine  on  daily  basis  through  the  consumption  of  coffee,  tea,  chocolates  and,  more  recently,  energy  drinks.  As  a  pharmacologically  potent  substance  caffeine  is  an  ingredient  of  many  medicaments  available  on  the  pharmaceutical  market of Republic of Serbia without a doctor’s prescription. Besides that, caffeine acts as a psychoactive  stimulant,  mild  diuretic,  and  displays  an  interaction  with  some  medicaments  due  to  the  induction  of  CYP1  and  CYP2  isoenzymes.  Keeping  in  mind  all  of  the  above,  it  is necessary to take into account the daily caffeine intake, as well as to control its content in energy drinks.Aim:  The  aim  of  this  study  was  spectrophotometric  determination  of  caffeine  content  in  energy drinks and tea, available in markets of the Republic of Serbia. Material  and  Methods:  Caffeine  was  determinated  by  UV/VIS  spectrophotometry  in  nine  types of energy drinks and eight samples of black and green tea. Results: The results showed that caffeine content in energy drink samples ranged from 26.81 to 35.44 mg/100mL and corresponds to declaration. The caffeine content in tea samples varies with the species (11.27-22.61 mg/100mL for green and 13.85-22.73 mg/100mL for black tea), but also with origin, growth conditions and tea processing.Conclusion: The obtained data suggest that UV/VIS spectrophotometry can be used for ro-utine determination and control of caffeine content in energy drinks and tea. It is important to  note  that  caffeine  intake  through  the  usual  daily  consumption  of  tea  and  energy  drinks  should not have a negative impact on human health, but this alkaloid could be additionally consumed through other sources, which is especially important for certain groups of patients.

AB  - Microbial polysaccharides, due to their unique physiochemical properties, have found application in the food industry, cosmetics, pharmacy and medicine. In the environment, microbes can use polysaccharides to alleviate the adverse effects of heavy metals in their close proximity. This adaptive property shows interesting potential for bioremediation. Herein, the effects of the exopolysaccharides (EPS) levan, produced by the bacterium Bacillus licheniformis NS032 and pullulan, produced by the fungus Aureobasidium pullulans CH-1 in the presence of copper (Cu2+) have been investigated for the first time on antioxidant enzyme activity, respiration and Cu2+ bioaccumulation of Daphnia magna as well as the bioluminescence of Vibrio fischeri. Both EPS decreased toxicity of Cu2+ in the acute test with D. magna. The activity of catalase (CAT) was significantly diminished after acute exposure to Cu2+ in comparison to treatments with Cu2+ and EPS, while in the prolonged acute exposure the CAT activity did not show statistically significant (P ≤ 0.05) differences between treatments with and without the EPS. According to ICP-MS results, during prolonged acute exposure of neonates, the bioaccumulation of Cu2+ in treatments without the EPS was 52.03 μg/g of biomass (wet), while in treatments with EPS, the bioaccumulation was lower by one order of magnitude. The respiration of neonates during acute exposure to Cu2+ with or without the EPS was monitored using the MicroOxymax respirometer, and the results show the EPS can positively effect the respiration. In the case of bacterial bioluminescence, the toxicity of Cu2+ decreased in treatments with EPS (30 min EC10) from 3.54 mg/L to 140.61 mg/L (levan) and 45.00 mg/L (pullulan). This study demonstrates protective effect of EPS against Cu2+ toxicity on D. magna and V. fischeri, and opens the door for further investigation of potential application of levan and pullulan in bioremediation of heavy metals and mitigation of their adverse effects in the aquatic environment.

AB  - Vodeni organizmi su izloženi brojnim hemijskim supstancama različitih mehanizama toksičnosti i da bi se okarakterisali međusobni efekti važna je uporedna analiza hemijskih podataka i odgovarajućeg biološkog odgovora (biomarkeri) [1]. Slatkovodni, planktonski beskičmenjak Daphnia magna je dobro poznat model u ekotoksikologiji, zbog svoje visoke osetljivosti na toksične supstance i relativno lake kultivacije u laboratorijskim uslovima. Većina istraživanja o proceni toksičnosti različitih hemijskih supstanci bazira se na ispitivanju akutne toksičosti i letalne ili efektivne koncentracije supstance koje dovode do neželjenog efekta u 50 % slučajeva (LC50/EC50), međutim neophodne su i detaljnije informacije o toksičnosti, koje bi uključile subletalne efekte i senzitivnije biomerkere [2]. Pošto bakar i njegova jedinjenja spadaju u vodeće zagađujuće supstance vode, sprovedene su i evaluirane brojne procene njegovih opasnosti i/ili negativnih efekata (US EPA 2007;EU 2007) [3]. Homeostaza bakra u akvatičnim organizmima uključuje regulisan unos,transport i ekskreciju koja je slična kao kod sisara. Studije na D. magna, koje su bile izložene subletalnim koncentracijama bakra, pokazuju pojačan oksidativni stres u jedinkama [4]. U ovoj studiji praćena je potrošnja O2 i produkcija CO2 kod jedinki D. magna tokom48 h izlaganja Cu2+ jonima. Respiracija D. magna (MicroBioTests Inc.) neonata praćena je 48 h pomoću dvanaestokanalnog Micro-Oxymax respirometra (Columbus Instruments, SAD). U intervalima od 4 h merena je koncentracija O2, paramagnetnim senzorom, a CO2 infracrvenim senzorom, pri čemu je tokom celokupnog trajanja eksprerimenta sistem bio zatvoren. Uzorci su pripremani u providnim Micro-Oxymax bocama zapremine 500 mL u kojima je bilo po 100 mL tečne podloge i 20 neonata. Korišćen je AdaM medijum (Aachener Daphnien Medium) [5]. Koncentracija Cu2+ jona bila je 50 μg/mL i odabrana je prema literaturno određenoj EC50 vrednosti za CuSO4 [6]. Jedinke nisu hranjene tokom eksperimenta i izlagane su na temperaturi od 20±2 ºC i fotoperiodu 16 h dan/8 h noć. Dobijeni podaci su evaluirani Micro-Oxymax softverom i određena je kumulativna potrošnja/proizvodnja gasova (μL). Nakon izlaganja praćena je imobilizacija neonata, a rezultati su izraženi kao procenat mortaliteta. Dva dana nakon izlaganja D. magna sa Cu2+ jonima, zabeležen je mortalitet jedinki od 75 %. Test je bio validan, jer nije zabeležen mortalitet u kontrolnoj grupi. Kod organizama koji su bili izloženi jonima bakra kumulativna potrošnja O2 je znatno manja tokom celog eksperimenta, dok je kumulativna produkcija CO2 u prvih 24 h manja, a dalje razlike nisu uočene, što se može pripisati dekompoziciji imobilisanih jedinki. Na osnovu dobijenih rezultata zaključeno je da se test na MicroOxymax respirometru može koristiti kao dodatni parametar za procenu akutnih efekata toksičnih susptanci na organizam D. magna.

U ovoj studiji praćena je potrošnja O2 i produkcija CO2 kod jedinki D. magna tokom48 h izlaganja Cu2+ jonima. Respiracija D. magna (MicroBioTests Inc.) neonata praćena je 48 h pomoću dvanaestokanalnog Micro-Oxymax respirometra (Columbus Instruments, SAD). U intervalima od 4 h merena je koncentracija O2, paramagnetnim senzorom, a CO2 infracrvenim senzorom, pri čemu je tokom celokupnog trajanja eksprerimenta sistem bio zatvoren. Uzorci su pripremani u providnim Micro-Oxymax bocama zapremine 500 mL u kojima je bilo po 100 mL tečne podloge i 20 neonata. Korišćen je AdaM medijum (Aachener Daphnien Medium) [5]. Koncentracija Cu2+ jona bila je 50 μg/mL i odabrana je prema literaturno određenoj EC50 vrednosti za CuSO4 [6]. Jedinke nisu hranjene tokom eksperimenta i izlagane su na temperaturi od 20±2 ºC i fotoperiodu 16 h dan/8 h noć. Dobijeni podaci su evaluirani Micro-Oxymax softverom i određena je kumulativna potrošnja/proizvodnja gasova (μL). Nakon izlaganja praćena je imobilizacija neonata, a rezultati su izraženi kao procenat mortaliteta. Dva dana nakon izlaganja D. magna sa Cu2+ jonima, zabeležen je mortalitet jedinki od 75 %. Test je bio validan, jer nije zabeležen mortalitet u kontrolnoj grupi. Kod organizama koji su bili izloženi jonima bakra kumulativna potrošnja O2 je znatno manja tokom celog eksperimenta, dok je kumulativna produkcija CO2 u prvih 24 h manja, a dalje razlike nisu uočene, što se može pripisati dekompoziciji imobilisanih jedinki. Na osnovu dobijenih rezultata zaključeno je da se test na MicroOxymax respirometru može koristiti kao dodatni parametar za procenu akutnih efekata toksičnih susptanci na organizam D. magna.",

AB  - The aim of this study was to investigate the degradation of the non-ionic surfactant Triton X-100 (TX-100) by using an advanced oxidation process in a non-thermal plasma reactor based on water falling film dielectric barrier discharge (DBD). The effects of two catalytic plasma systems, Fe2+/DBD and H2O2/DBD, were tested to improve the degradation of TX-100 and the mineralization efficiency in the DBD reactor. Both catalytic systems exhibited significant improvements in degradation efficiency, especially in the beginning of the treatment: the efficiency increased from 23 to 88 and 50%, for 5 mgL(-1) Fe2+/DBD and 10 mmol L-1 H2O2/DBD, respectively. The mineralization efficiency of TX-100 in the non-catalytic DBD treatment was very low (1%), but with addition of catalysts, the mineralization efficiency was drastically improved, with H2O2/DBD at 4-34% (depending on the H2O2 concentration) and Fe2+/DBD at 2-21% (depending on the Fe2+ concentration). Degradation products of TX-100 in non-catalytic and two catalytic systems were identified using UHPLC-Orbitrap-MS. Based on the degradation products that were identified, a simple mechanistic scheme was proposed. MS analysis revealed that degradation of TX-100 in the DBD reactor occurred by shortening the ethoxy chain. In the presence of catalysts, there are additional reactions of cleavage of the alkyl chain followed by formation of polyethoxylated phenol (H2O2/DBD) and addition of OH center dot radicals onto the aromatic ring (Fe2+/DBD). The final degradation products did not cause any significant toxic effects to Vibrio fischeri or Artemia salina.

AB  - Two anionic surfactants (sodium lauryl sulfate - SDS and sodium dodecylbenzenesulfonate - SDBS) were treated with dielectric barrier discharge. Loss of surfactant activity, decrease in chemical oxygen demand (COD) and total organic carbon (TOC) as well as lower toxicity of degradation products was determined. Effects of catalysts - hydrogen peroxide and iron (II), on the above mentioned parameters, were determined. Catalysts affected the degradation of SDBS, but in the case of SDS, catalysts had no effect on degradation. Both catalysts induced the decrease of COD and TOC values. Toxicity of the solutions after the plasma treatment was lower in all the systems tested.

AB  - Fourteen metals and metalloids were determined in Conyza canadensis L. harvested from the fly ash landfill of the thermoelectric power plant "Kolubara" (Serbia). Fly ash samples were collected together with the plant samples and subjected to sequential extraction according to the three-step sequential extraction scheme proposed by the Community Bureau of Reference (BCR; now the Standards, Measurements and Testing Program). The contents of metals and metalloids were determined by inductively coupled plasma optical emission spectrometry (ICP-OES) in plant root and the aboveground part and correlated with their contents in the fly ash samples. The bioconcentration factor (BCF) and translocation factors (TF) were calculated to access uptake of metals from fly ash and their translocation to the aboveground part. Results regarding As revealed that fly ash samples in the proximity of the active cassette had higher amounts of the element. Principal component analysis (PCA) showed that As had no impact on the classification of plant parts. BCF for As ranged from 1.44 to 23.8 and varied, depending on the investigated area; TF for As ranged from 0.43 to 2.61, indicating that the plant translocated As from root to shoot. In addition to As, Conyza canadensis L. exhibited efficient uptake of other metals from fly ash. According to the calculated BCF and TF, the plant retained Al, Fe and Cr in the root and translocated Zn, Cd, Cu and As from root to shoot in the course of the detoxifying process.

AB  - Composite material Zr-doped TiO2, suitable for the removal of arsenic from water, was synthetized with fast and simple microwave-hydrothermal method. Obtained material, Zr-TiO2, had uniform size and composition with zirconium ions incorporated into crystal structure of titanium dioxide. Synthetized composite material had large specific surface area and well-developed micropore and mesopore structure that was responsible for fast adsorption of As(III) and As(V) from water. The influence of pH on the adsorption capacity of arsenic was studied. The kinetics and isotherm experiments were also performed. The treatment of natural water sample containing high concentration of arsenic with composite material Zr-TiO2 was efficient. The concentration of arsenic was reduced to the value recommended by WHO.

AB  - Experimental results of non-thermal plasma (NTP) utilization for degradation of 4-chlorphenol (4CP) with screening of toxicity were presented in this study. Degradation of 4CP was tested in the presence of homogeneous catalysts: hydrogen peroxide (H2O2) and iron (II) (Fe2+). The rate of degradation through eight consecutive passes of the 4CP solution in the NTP reactor was considered. Products of degradation as organic acids (acetic, formic or oxalic acid) and chloride were quantified using ion chromatography (IC). Anemia salina was used for the toxicity screening assay in order to estimate the potential and consequences of NTP reactor application in water treatment. The measured concentration of 4CP and degradation products confirmed very efficient removal of these substances from the water during the NTP treatment with the addition of a catalyst. Concerning bioassay, a significant difference in toxicity was determined between initial solution of 4CP in comparison with the solution exposed to catalytic NTP treatment. (C) 2015 Elsevier B.V.

AB  - Pharmaceutical compounds have been detected frequently in surface and ground water. Advanced Oxidation Processes (AOPs) were reported as very efficient for removal of various organic compounds. Nevertheless, due to incomplete degradation, toxic intermediates can induce more severe effects than the parent compound. Therefore, toxicity studies are necessary for the evaluation of possible uses of AOPs. In this study the effectiveness and capacity for environmental application of three different AOPs were estimated. They were applied and evaluated for removal of ibuprofen from water solutions. Therefore, two treatments were performed in a non-thermal plasma reactor with dielectric barrier discharge with and without a homogenous catalyst (Fe2+). The third treatment was the Fenton reaction. The degradation rate of ibuprofen was measured by HPLC-DAD and the main degradation products were identified using LC-MS TOF. Twelve degradation products were identified, and there were differences according to the various treatments applied. Toxicity effects were determined with two bioassays: Vibrio fischeri and Artemia salina. The efficiency of AOPs was demonstrated for all treatments, where after 15 min degradation percentage was over 80% accompanied by opening of the aromatic ring. In the treatment with homogenous catalyst degradation reached 99%. V. fischeri toxicity test has shown greater sensitivity to ibuprofen solution after the Fenton treatment in comparison to A. salina.

U odnosu na početni (netretirani) rastvor 4CP, nakon tretmanaDBD/Fe2+porcenat preživelih larvi A. salina se povećao za 95%.Degradacija reaktivnih azo boja (RG15, RY125 i RB52) je ispitana primenomEAOP (eng.

AB  - In this thesis the degradation of 4CP (para-chlorophenol), reactive azo dyes andibuprofen was studied using the Advanced Oxidation Processes (AOP) such as Fenton'sreagent, Dielectric Barrier Discharge (DBD) reactor and electrochemical degradation.The efficiency of degradation was optimized by addition of a homogenous catalyst(Fe2+ or H2O2) to the reactor and also by applying different electrode materials or byvarying the duration of the treatment. The decolorization (%) of reactive azo dyes wasmonitored by UV-VIS technique and the efficiency of degradation was monitored by ionchromatography (IC) and HPLC. Identification of the main degradation products as well asthe degradation mechanisms were determined by LC-MS (TOF) technique. Themineralization efficiency was determined through the value of TOC.Treatment by non-thermal plasma (NTP) in the DBD reactor was studied during thedegradation of 4CP to biodegradable and less toxic intermediates. Experimental work wasorganized into three systems for 4CP degradation: DBD, DBD/H2O2 and DBD/Fe2+. Theefficiency of 4CP degradation was evaluated by the number of passing of the solutionthrough the DBD reactor, as well as the amountn of the introduced energy density (kJ/L).The concentration of 4CP, as well as the concentration of the individual degradationproducts were measured after the each pass.The concentrations of the 4CP degradation products such as acetic, formic or oxalicacid were lower in the system where the iron was used as the catalyst (DBD/Fe2+) incomparison to the system with hydrogen peroxide as the catalyst (DBD/H2O2). Theconcentration of chloride in all three systems increased during the degradation process. Thehighest concentration of chlorides was recorded in the system with the addition of Fe2+as acatalyst. The toxicity assessment of initial solution of 4CP as well as the solution which hasbeen treated in all three systems was performed using A.salina. In comparison to untreatedsolution of 4CP the solution treated in DBD/Fe2+ system had increased percentage of larvalsurvival by 95%.Degradation of reactive azo dyes (RG15, RY125 or RB52) was studied using theEAOP (Eletrochemical Advance Oxidation Processes) techniques in undividedtwoelectrode cell, where the Fisher platinum electrode was applied as anode and the Pd, Zror C electrodes were applied as cathode. The most effective system for the degradation ofRG15 and RY125 was Pt-Pd system, while for the RB52 the Pt-Zr system was moreapplicable. Ecotoxicological effect of reactive dyes RG15 and RY125 was the lowest or notdetected in the dye solution after the Pt-Pd treatment. In the case of RB52 ecotoxicologicaleffect increased for both A.salina and V.fischeri after the EAOP treatment.In the case of ibuprofen degradation, the NTP treatment (15 min) was improved byaddition of a homogeneous catalyst, which contributed to the efficiency of degradation(99%) and the mineralization of polluting substances in comparison to DBD and the Fentonprocess (about 80%). After all treatments, by analysis of mass spectra 12 degradationproducts of ibuprofen were identified: five aromatic and seven aliphatic products. In thesolution after the DBD/Fe2+treatment only 4 aliphatic carboxylic acids were detected.Ecotoxicological effect of the ibuprofen solution treated in the DBD reactor as well as inthe DBD/Fe2+ system was not detected. In relation to A.salina, V. fischeri has shown greatersensitivity to degradation products which appeared during the Fenton treatment. The toxiceffect of ibuprofen solution after the Fenton treatment was categorized as class III, that is"Toxic".The highest degradation percentage of ibuprofen was achieved by application ofEAOPs in the Pt - Pd system (98%), with the current of 100 mA and at the pH value of 3.The toxic effect expressed as the mortality (%) of A. saline was less than 30% at the highesttested concentration 100% (c, v/v) of ibuprofen solution treated in the Pt-Pd system. TheV.fischeri was the more sensitive model for the assessment of the ibuprofen degradationproducts toxic effect after the Pt-Pd treatment in comparison to A.salina.

The toxicity assessment of initial solution of 4CP as well as the solution which hasbeen treated in all three systems was performed using A.salina. In comparison to untreatedsolution of 4CP the solution treated in DBD/Fe2+ system had increased percentage of larvalsurvival by 95%.Degradation of reactive azo dyes (RG15, RY125 or RB52) was studied using theEAOP (Eletrochemical Advance Oxidation Processes) techniques in undividedtwoelectrode cell, where the Fisher platinum electrode was applied as anode and the Pd, Zror C electrodes were applied as cathode. The most effective system for the degradation ofRG15 and RY125 was Pt-Pd system, while for the RB52 the Pt-Zr system was moreapplicable. Ecotoxicological effect of reactive dyes RG15 and RY125 was the lowest or notdetected in the dye solution after the Pt-Pd treatment. In the case of RB52 ecotoxicologicaleffect increased for both A.salina and V.fischeri after the EAOP treatment.In the case of ibuprofen degradation, the NTP treatment (15 min) was improved byaddition of a homogeneous catalyst, which contributed to the efficiency of degradation(99%) and the mineralization of polluting substances in comparison to DBD and the Fentonprocess (about 80%). After all treatments, by analysis of mass spectra 12 degradationproducts of ibuprofen were identified: five aromatic and seven aliphatic products. In thesolution after the DBD/Fe2+treatment only 4 aliphatic carboxylic acids were detected.Ecotoxicological effect of the ibuprofen solution treated in the DBD reactor as well as inthe DBD/Fe2+ system was not detected. In relation to A.salina, V. fischeri has shown greatersensitivity to degradation products which appeared during the Fenton treatment. The toxiceffect of ibuprofen solution after the Fenton treatment was categorized as class III, that is"Toxic".The highest degradation percentage of ibuprofen was achieved by application ofEAOPs in the Pt - Pd system (98%), with the current of 100 mA and at the pH value of 3.The toxic effect expressed as the mortality (%) of A. saline was less than 30% at the highesttested concentration 100% (c, v/v) of ibuprofen solution treated in the Pt-Pd system. TheV.fischeri was the more sensitive model for the assessment of the ibuprofen degradationproducts toxic effect after the Pt-Pd treatment in comparison to A.salina.",

AB  - The objectives of this study were to determine the concentrations of Pb, Cd, As, Cr, Cu, Co, Ni, Zn, Ba, Fe, Al and Ag in Erigeron canadensis L. growing on fly ash landfill of power plant "Kolubara", Serbia. The content of each element was determined in every part of plant separately (root, stalk and inflorescence) and correlated with the content of elements in each phase of sequential extraction of fly ash. In order to ambiguously select the factors that are able to decidedly characterize the particular part of plant, principal component analysis (PCA) and partial least squares discriminant analysis (PLS-DA) were performed. The bioconcentration factors and translocation factors for each metal were calculated in order to determine the feasibility of the use of plant E. canadensis L. for phytoremediation purpose. There were strong positive correlations between metals in every part of plant samples, and metals from pseudo total form of sequential extraction indicate that the bioavailability of elements in fly ash is similarly correlated with total form. Retained Al, Fe, Cr and Co in the root indicate its suitability for phytostabilization. This plant takes up Cd and Zn from the soil (bioconcentration factors (BCFs) greater than 1), transporting them through the stalk into the inflorescence (translocation factors (TFs) higher than 1). Regarding its dominance in vegetation cover and abundance, E. canadensis L. can be considered adequate for phytoextraction of Cd and Zn from coal ash landfills at Kolubara.

AB  - Microwave-hydrothermal method was used for the synthesis of TiO2 and TiO2 doped with zirconium. The method was fast and simple and adsorbents were used for removal of As(III) and As(V) from aqueous solutions. The adsorbents were characterized by BET surface area measurements and powder XRD. Experiments showed that TiO2 doped with 10% of Zr using the microwave-hydrothermal method have greater specific surface area and total pore volume in comparison with TiO2 synthesized using the same method. Better removal with doped adsorbent was obtained for both, As(III) and As(V). Further experiments were carried out with Zr doped TiO2 sorbent in order to examine kinetic of adsorption, influence of pH and effect of common anions present in natural waters.

AB  - Electrochemical treatment is a new trend for the purification of textile industry wastewater which containing azo dyes. In this paper the electrochemical treatment was used for decolorization of azo dye Reactive Blue 52. The efficiency of decolorization was compared for different electrochemical systems which were all equipped with Fisher platinum electrode as anode and a different cathode (Zr, Pd, C) in sodium sulfate as supporting electrolyte. In order to find optimal conditions the influence of various voltage and pH values of initial dye solution was studied. Decolorization rate was monitored by spectrophotometer while degradation products were identified by high performance liquid chromatography-diode array detector (HPLC-DAD). Results of HPLC analysis confirmed presence of various degradation products in electrochemical systems, which indicated different mechanism of degradation. This was also confirmed by Ek-t curve. In terms of power consumption the most cost effective system was with the graphite cathode (C/Pt).

AB  - The application of various electrodes for in situ degradation of Reactive Yellow 125 (RY125) and Reactive Green 15 (RG15) dyes, as well as ecotoxicity screening test of their degradation products were studied in this paper. The degradation process was performed in a two-electrode cylindrical cell, with Fisher platinum electrode as anode and Pd, Zr, or C electrodes as cathode; in 0.1 M Na2SO4 as supporting electrolyte. The optimal conditions (voltage and pH value) for degradation were determined in a platinum-palladium (Pt-Pd) model system for 200 mg/L of both reactive dyes. Then the electrolysis with other electrodes was conducted under the same conditions. Decolorization was monitored spectrofotometrically (UV-Vis) and the degradation efficiency was confirmed by HPLC technique with a DAD detector. Differences in degradation efficiency were observed between these three electrochemical systems (Pt-Pd, Pt-Zr, and Pt-C). The Pt-Pd system was the most efficient for the degradation of both reactive dyes. Achieved decolorization percentage for RG15 and RY125 were 98% and 97%, respectively. The ecotoxicity assessment of degradation products was performed using Anemia sauna. Toxicity data were compared by Kruskal-Wallis one-way analysis and pair-wise group comparisons with Mann-Whitney U tests. Statistically significant differences (p lt 0.05) in mortality (%) for Pt-Pd and Pt-Zr systems were determined between treated and untreated dye solutions of RG15. System Pt-C had no detectable significance in treatment of solutions of both dyes.

AB  - Inorganic salts improve the coloration of textiles, which increases the pollution load of dye-house effluent in general. Decolorization of the reactive textile dye C.I. Reactive Black 5 was studied using Advanced Oxidation Processes (AOPs) in a non-thermal plasma reactor, based on the coaxial water falling film Dielectric Barrier Discharge (DBD). The initial dye concentration in the solution was 40.0 mg L-1. The effects of the addition of different high concentrations of inorganic salt (NaCl, Na2SO4 and Na2CO3) on the degree of decolorization were studied. The dye solution was recirculated through the DBD reactor with an applied energy density of 45.0-315 kJ L-1. The influence of residence time was investigated after 5 min and 24 h of plasma treatment. Decolorization of the dye was monitored spectrophotometrically. The pH value and the conductivity of the dye solution were measured after each recirculation. The most effective decolorization of over 90 % was obtained with the addition of NaCl (50 g L-1) with an applied energy density of 135 kJ L-1 and after a residence time of 24 h of plasma treatment. Decolorization of the solutions containing inorganic salts Na2SO4 and Na2CO3 were lower than for the solution without salt.
AB  - Neorganske soli poboljšavaju bojenje tekstila. Povećana koncentracija soli u otpadnoj vodi koja potiče iz tekstilne industrije dodatno opterećuje otpadnu vodu u celini. U okviru ovog rada proučavano je obezbojavanje reaktivne tekstilne boje reaktivno crno 5 koristeći unapređeni oksidacioni proces (AOP) pomoću koaksijalnog reaktora na bazi netermičke plazme. Reaktor radi na principu dielektričnog barijernog pražnjenja (DBD), pri čemu je jedan sloj dielektrika tanak sloj tretirane vode koji se konstantno obnavlja (protočni tip reaktora). Početna koncentracija boje u tretiranom rastvoru je bila 40,0 mg L-1. Proučavan je uticaj različitih visokih koncentracija neorganskih soli (NaCl, Na2SO4 i Na2CO3) na stepen obezbojenja. Rastvor boje je sedam puta recirkulasan kroz DBD reaktor, što odgovara primenjenoj gustini energije od 45 do 315 kJ L-1. Procenat obezbojenja rastvora boje je meren posle 5 min i posle 24 h od tretmana plazmom. Obezbojavanje boje je praćeno pomoću spektrofotometrijskog merenja. Posle svake recirkulacije rastvora boje merene su promena pH vrednosti i provodljivost rastvora. Najefikasnije obezbojenje od preko 90 % dobijeno je u sistemu sa dodatkom 50 g L-1 NaCl, pri primenjenoj gustini energije od 45 kJ L-1 i posle 24 sata od plazma tretmana. Obezbojenja rastvora boje koji sadrže neorganske soli Na2SO4 i Na2CO3 bila su niža nego kod rastvora boje bez dodatka soli.

AB  - The determination of Cu by anodic stripping voltammetry using a Nafion-modified glassy carbon electrode incorporated with Cu-DPABA complex (Cu-DPABA-NA/GCE) was described. Cu was accumulated in acetic buffer pH 4 at potential of -1.4 V (vs. Ag/AgCl ref. electrode) and then determined with DPASV. Under the optimum conditions the calibration curve was linear in the range 7.0 x 10(-9) -5.0 x 10(-5) mol/L. The detection limit was 3.0 x 10(-9) mol/L. Different parameters and conditions, such as membrane ingredients, accumulation time and pH value was optimized. A study of the interfering substances was also performed. A significant increase in current was achieved at the modified electrode compared to a bare glassy carbon electrode. For explanation of voltammetric behavior of modified electrode in copper solution, cyclic voltammograms were recorded. The electrode was applied in the direct determination of Cu in water.
