AB  - Aluminum pillared clay was synthesized and impregnated with Co2+ (CoAP), using incipient wetness impregnation method. The obtained CoAP was characterized by chemical analysis, XRPD, SEM with EDS, XPS and low temperature N2 physisorption. By these methods the incorporation of Co2+ was confirmed in both micro and mesoporous region. The synthesized material was investigated as a catalyst in catalytic oxidation of organic water pollutants – dyes – in the presence of Oxone® (peroxymonosulfate). Oxone® is a precursor of sulfate radicals. Tartrazine was chosen as a model dye pollutant. The influence of the mass of the catalyst, temperature and initial pH was investigated. Temperature increase was beneficial for dye degradation rate. The reaction rate was the highest for initial pH values around those corresponding to neutral conditions, somewhat slower for pH < 4 values, while for pH > 10 decolorization was significantly less expressed. Along with decolorization of tartrazine solution the formation and degradation of tartrazine catalytic oxidation products were monitored using UV–Vis spectroscopy. CoAP was found to be efficient catalyst in Oxone® induced catalytic degradation of both tartrazine and detected products of its degradation.

AB  - Ten organic solvents (triethanolamine, diethanolamine, ethylene glycol, methyl ethyl ketone, n-hexane, triethylamine, ethylene glycol dimethyl ether, glycerol, tetrahydrofuran and dioxane) were applied as cosolvents in the CaO-catalyzed ethanolysis of sunflower oil performed in a batch stirred reactor under the following reaction conditions: temperature 70 °C, ethanol-to-oil mole ratio 12:1, initial catalyst concentration 1.374 mol·L -1 and amount of cosolvent 20 % based on the oil amount. The main goals were to assess the effect of the used cosolvents on the synthesis of fatty acid ethyl esters (FAEE) and to select the most efficient one with respect to the final FAEE content, reaction duration and safety profile. In the absence of any cosolvent, the reaction was rather slow, providing a FAEE content of only 89.7±1.7 % after 4 h. Of the tested cosolvents, diethanolamine, triethanolamine and ethylene glycol significantly accelerated the ethanolysis reaction, whereby the last two provided a final FAEE content of 93.1±2.1 and 94.1±1.5 %, respectively, within 0.5 h. However, because of its safety profile, triethanolamine was selected as the best cosolvent for the ethanolysis of sunflower oil catalyzed by calcined CaO.

AB  - Triethanolamine was applied as an efficient „green“ cosolvent for biodiesel production by CaO-catalyzed ethanolysis of sunflower oil. The reaction was conducted in a batch stirred reactor and optimized with respect to the reaction temperature (61.6-78.4 °C), the ethanol-to-oil molar ratio (7:1-17:1) and the cosolvent loading (3-36 % of the oil weight) by using a rotatable central composite design (RCCD) combined with the response surface methodology (RSM). The optimal reaction conditions were found to be: the ethanol-to-oil molar ratio of 9:1, the reaction temperature of 75 °C and the cosolvent loading of 30 % to oil weight, which resulted in the predicted and actual fatty acid ethyl ester (FAEE) contents of 98.8 % and 97.9±1.3 %, respectively, achieved within only 20 min of the reaction. Also, high FAEE contents were obtained with expired sunflower oil, hempseed oil and waste lard. X-ray diffraction analysis (XRD) was used to understand the changes in the CaO phase. The CaO catalyst can be used without any treatment in two consecutive cycles. Due to the calcium leaching into the product, an additional purification stage must be included in the overall process.

AB  - A series of arylazo pyridone dyes was synthesized by changing the type of the substituent group in the diazo moiety, ranging from strong electron-donating to strong electron-withdrawing groups. The structural and electronic properties of the investigated dyes was calculated at the M062X/6-31 + G(d,p) level of theory. The observed good linear correlations between atomic charges and Hammett sigma(p) constants provided a basis to discuss the transmission of electronic substituent effects through a dye framework. The reactivity of synthesized dyes was tested through their decolorization efficiency in TiO2 photocatalytic system (Degussa P-25). Quantitative structure activity relationship analysis revealed a strong correlation between reactivity of investigated dyes and Hammett substituent constants. The reaction was facilitated by electron-withdrawing groups, and retarded by electron-donating ones. Quantum mechanical calculations was used in order to describe the mechanism of the photocatalytic oxidation reactions of investigated dyes and interpret their reactivities within the framework of the Density Functional Theory (DFT). According to DFT based reactivity descriptors, i.e. Fukui functions and local softness, the active site moves from azo nitrogen atom linked to benzene ring to pyridone carbon atom linked to azo bond, going from dyes with electron-donating groups to dyes with electron-withdrawing groups.

AB  - A series of arylazo pyridone dyes was synthesized by changing the type of the substituent group in the diazo moiety, ranging from strong electron-donating to strong electron-withdrawing groups. The structural and electronic properties of the investigated dyes was calculated at the M062X/6-31 + G(d,p) level of theory. The observed good linear correlations between atomic charges and Hammett sigma(p) constants provided a basis to discuss the transmission of electronic substituent effects through a dye framework. The reactivity of synthesized dyes was tested through their decolorization efficiency in TiO2 photocatalytic system (Degussa P-25). Quantitative structure activity relationship analysis revealed a strong correlation between reactivity of investigated dyes and Hammett substituent constants. The reaction was facilitated by electron-withdrawing groups, and retarded by electron-donating ones. Quantum mechanical calculations was used in order to describe the mechanism of the photocatalytic oxidation reactions of investigated dyes and interpret their reactivities within the framework of the Density Functional Theory (DFT).

AB  - The external invertase isoform 1 (EINV1) was immobilised on eight differently modified beidellite nanoclays, Modifications were composed of organo-modification with different amounts of surfactant - hexadecyl trimethylammonium cation (HDTMA), pillaring with Al/Fe containing polyhydroxy cations and acid modification of Na-enriched and pillared clays. The modified nanoclays were characterised by XRD, N-2-physisorption, SEM and FT-IR spectroscopy. The amount of bound enzyme activity was significantly influenced by the modification of beidellite ranging from 50 to remarkable 2200 U/g. Biochemical characterization was performed for five modified nanoclays showing the highest enzyme activity after invertase immobilisation. The investigation demonstrated that after immobilisation the structure and the catalytic properties of invertase were preserved, while Km values were slightly increased from 26 to 37 mM. immobilisation significantly improved thermal and storage stability of EINV1. Results indicate that beidellite nanoclays obtained by low cost modifications can be applied as a suitable support for the immobilisation of invertase. The immobilizate can be efficiently engaged in sucrose hydrolysis in batch reactor.

AB  - U sklopu ove doktorske disertacije proučavana je elektrohemijska oksidacija 4-nitrofenola na modifikovanoj elektrodi od staklastog ugljenika (Glassy CarbonElectrode – GCE). Za modifikaciju GCE korišćene su natrijumski izmenjene iorganogline.U tu svrhu, urađena je natrijumskа izmena smektitne faze u glinama bentonitnogtipa iz dva nalazišta u Srbiji „Bogovina“ i „Mečji Do“. Na-izmenjene gline su zatimmodifikovane kvaternernim alkilamonijum katjonom i dobijeni su nanomaterijali sahibridnom organsko-neorganskom površinom – organogline. Modifikacija je urađenainterkalacijom različitih količina benziltrimetilamonijum (BTMA) katjona umeđulamelarni prostor smektita.Polazni i modifikovani uzorci su karakterisani hemijskom analizom, rendgenskodifrakcionom metodom, dok su pored ovih metoda za karakterizaciju modifikovanihmaterijala korišćene i metode infracrvene spektroskopije i niskotemperaturnefizisorpcije azota.Kod svih modifikovanih uzoraka je potvrđeno da je modifikacija polaznihuzoraka bila uspešna. Rezultati elementalnе analize su pokazali da je za većeprimenjene količine BTMA katjona prilikom modifikacije ugrađena količina ovihkatjona bila manja od teorijski izračunatih vrednosti. Rendgenskom difrakcionomanalizom potvrđeno je da je primenjena modifikacija dovela do interkalacije BTMAkatjona u međulamelarni prostor smektita u obliku monosloja. Infracrvena analiza jepotvrdila ugradnju BTMA katjona u strukturu smektita.Eksperimenti koji su uključivali adsorpciju 4-nitrofenola na ispitivanimuzorcima su pokazali da organomodifikacija menja adsorpcioni afinitet glina prema 4-nitrofenolu. Povećanje količine interkaliranih BTMA katjona u međulamelarnomprostoru smektita ima za posledicu povećanje adsorpcije 4-nitrofenola. Ovaj trend senastavlja sve dok količina katjona dostigne vrednost kada dodatno interkalisani BTMAkatjoni nisu dostupni za interakciju sa 4-nitrofenolom. Ispitivanja elektrooksidacije 4-nitrofenola metodom ciklične voltametrije načistoj GCE i GCE koja je modifikovana sa svakom od Na-izmenjenih i organoglina,pojedinačno, pokazala su da modifikacija GCE dobijenim materijalima znatno utiče nagustinu struje i stabilnost modifikovanih elektroda. Gustine struje koje su dobijene začistu CGE su 15-47 puta manje od struja dobijenih za modifikovane GCE, pri čemu ječista GCE pokazala nagli gubitak aktivnosti odmah nakon prvog ciklusa. Veće vrednostigustine struje kod BTMA modifikovanih GCE u odnosu na one modifikovane sa Naizmenjenimglinama ukazuju da ugradnja BTMA katjona u strukturu smektita dovodi dopovećanja vrednosti gustine struje. Nakon deset ciklusa aktivnost modifikovanihelektroda najviše opada za GCE modifikovane Na-izmenjenim uzorcima. Odsustvopikova koji se odnose na oksidaciju hidrohinona i katehola i drastična deaktivacija ovihelektroda ukazuju da je dominantan put oksidacije 4-nitrofenola kod GCEmodifikovanih Na-izmenjenim glinama onaj kod kog dolazi do stvaranja polimera.Vrednosti gustine struje oksidacije 4-nitrofenola na potencijalu  1,2 V opadajusa porastom ugradnje BTMA katjona dok stabilnost elektroda raste u suprotnom smeru.Stabilnost se može objasniti time da reakcioni put oksidacije 4-nitrofenola koji vodi dostvaranja polimernih proizvoda postaje manje značajan sa povećanjem količineugrađenih BTMA katjona kod BTMA-bentonit modifikovanih GCE. Nešto veće strujeza elekrode modifikovane organoglinama na bazi gline iz nalazišta „Bogovina“ uodnosu na one na bazi gline iz nalazišta „Mečji Do“ mogu se pripisati većem sadržajugvožđa u strukturi smektita iz nalazišta „Bogovina“. Gvožđe prisutno u strukturismektita najverovatnije ima ulogu posrednika u prenosu elektrona i utiče na poraststruje oksidacije 4-nitrofenola.Metodom diferencijalne pulsne voltametrije određen je detekcioni limit zanajstabilnije modifikovane GCE na bazi glina iz oba ispitivana nalazištа, pri čemu sudobijene vrednosti detekcionog limita slične vrednostima koji su drugi autori dobili prielektrohemijskom određivanju 4-nitrofenola.Rezultati prikazani u ovoj doktorskoj disertaciju ukazuju da modifikovanjeelektrode od staklastog ugljenika nanošenjem tankog sloja glina modifikovanihbenziltrimetilamonijum katjonima mogu poslužiti za razvijanje elektrode koja bi sekoristila u detekciji 4-nitrofenola prisutnog u otpadnim vodama.

Za modifikaciju GCE korišćene su natrijumski izmenjene iorganogline.U tu svrhu, urađena je natrijumskа izmena smektitne faze u glinama bentonitnogtipa iz dva nalazišta u Srbiji „Bogovina“ i „Mečji Do“. Na-izmenjene gline su zatimmodifikovane kvaternernim alkilamonijum katjonom i dobijeni su nanomaterijali sahibridnom organsko-neorganskom površinom – organogline. Modifikacija je urađenainterkalacijom različitih količina benziltrimetilamonijum (BTMA) katjona umeđulamelarni prostor smektita.Polazni i modifikovani uzorci su karakterisani hemijskom analizom, rendgenskodifrakcionom metodom, dok su pored ovih metoda za karakterizaciju modifikovanihmaterijala korišćene i metode infracrvene spektroskopije i niskotemperaturnefizisorpcije azota.Kod svih modifikovanih uzoraka je potvrđeno da je modifikacija polaznihuzoraka bila uspešna. Rezultati elementalnе analize su pokazali da je za većeprimenjene količine BTMA katjona prilikom modifikacije ugrađena količina ovihkatjona bila manja od teorijski izračunatih vrednosti. Rendgenskom difrakcionomanalizom potvrđeno je da je primenjena modifikacija dovela do interkalacije BTMAkatjona u međulamelarni prostor smektita u obliku monosloja. Infracrvena analiza jepotvrdila ugradnju BTMA katjona u strukturu smektita.Eksperimenti koji su uključivali adsorpciju 4-nitrofenola na ispitivanimuzorcima su pokazali da organomodifikacija menja adsorpcioni afinitet glina prema 4-nitrofenolu. Povećanje količine interkaliranih BTMA katjona u međulamelarnomprostoru smektita ima za posledicu povećanje adsorpcije 4-nitrofenola. Ovaj trend senastavlja sve dok količina katjona dostigne vrednost kada dodatno interkalisani BTMAkatjoni nisu dostupni za interakciju sa 4-nitrofenolom. Ispitivanja elektrooksidacije 4-nitrofenola metodom ciklične voltametrije načistoj GCE i GCE koja je modifikovana sa svakom od Na-izmenjenih i organoglina,pojedinačno, pokazala su da modifikacija GCE dobijenim materijalima znatno utiče nagustinu struje i stabilnost modifikovanih elektroda. Gustine struje koje su dobijene začistu CGE su 15-47 puta manje od struja dobijenih za modifikovane GCE, pri čemu ječista GCE pokazala nagli gubitak aktivnosti odmah nakon prvog ciklusa. Veće vrednostigustine struje kod BTMA modifikovanih GCE u odnosu na one modifikovane sa Naizmenjenimglinama ukazuju da ugradnja BTMA katjona u strukturu smektita dovodi dopovećanja vrednosti gustine struje. Nakon deset ciklusa aktivnost modifikovanihelektroda najviše opada za GCE modifikovane Na-izmenjenim uzorcima. Odsustvopikova koji se odnose na oksidaciju hidrohinona i katehola i drastična deaktivacija ovihelektroda ukazuju da je dominantan put oksidacije 4-nitrofenola kod GCEmodifikovanih Na-izmenjenim glinama onaj kod kog dolazi do stvaranja polimera.Vrednosti gustine struje oksidacije 4-nitrofenola na potencijalu  1,2 V opadajusa porastom ugradnje BTMA katjona dok stabilnost elektroda raste u suprotnom smeru.Stabilnost se može objasniti time da reakcioni put oksidacije 4-nitrofenola koji vodi dostvaranja polimernih proizvoda postaje manje značajan sa povećanjem količineugrađenih BTMA katjona kod BTMA-bentonit modifikovanih GCE. Nešto veće strujeza elekrode modifikovane organoglinama na bazi gline iz nalazišta „Bogovina“ uodnosu na one na bazi gline iz nalazišta „Mečji Do“ mogu se pripisati većem sadržajugvožđa u strukturi smektita iz nalazišta „Bogovina“. Gvožđe prisutno u strukturismektita najverovatnije ima ulogu posrednika u prenosu elektrona i utiče na poraststruje oksidacije 4-nitrofenola.Metodom diferencijalne pulsne voltametrije određen je detekcioni limit zanajstabilnije modifikovane GCE na bazi glina iz oba ispitivana nalazištа, pri čemu sudobijene vrednosti detekcionog limita slične vrednostima koji su drugi autori dobili prielektrohemijskom određivanju 4-nitrofenola.Rezultati prikazani u ovoj doktorskoj disertaciju ukazuju da modifikovanjeelektrode od staklastog ugljenika nanošenjem tankog sloja glina modifikovanihbenziltrimetilamonijum katjonima mogu poslužiti za razvijanje elektrode koja bi sekoristila u detekciji 4-nitrofenola prisutnog u otpadnim vodama.",

AB  - (99)Technetium is one of the largest components of nuclear waste material. In aqueous solutions Tc-99 is present as the pertechnetate oxoanion, (TcO4-)-Tc-99, which is highly soluble and mobile in groundwater under oxidizing conditions, thus posing a major environmental concern. In this study, a series of organo-modified bentonite clay samples was tested as adsorbents for the removal of radioactive (TcO4-)-Tc-99 from aqueous solution at room temperature. The influence of the hexadecyl trimethylammonium (HDTMA)/bentonite ratio on the adsorption ability of the organobentonites was investigated. It was found that the adsorbent in which the exchangeable cations were only partially substituted with HDTMA showed very low affinity toward pertechnetate. On the other hand, the adsorbents in which the HDTMA loading exceeded the cation exchange capacity (CEC) value had high efficiency. The behavior of such adsorbents was best described by a Freundlich isotherm, while for the sample in which the HDTMA loading was equal to the CEC, the linear adsorption isotherm was the most appropriate. The difference in adsorption performance of several adsorbents was discussed from the point of view of the interlayer arrangement of the HDTMA. The kinetics of pertechnetate adsorption on HDTMA-bentonites was tested and analyzed using different surface reaction- and diffusion-based kinetic models. For all the investigated adsorbents, the most appropriate kinetic model was the pseudo-second-order kinetics model. The obtained adsorption capacities were and HDTMA-bentonites with HDTMA loadings exceeding CEC value should be regarded as very promising adsorbents for the remediation of Tc-99 polluted waters.

AB  - Bentonite clay rich in smectite clay mineral from seldom investigated locality Mecji Do (MD) in Serbia was modified. The organomodification was performed with different loadings of benzyltrimethylammonium (BTMA) cation. The characterization of clay-based samples was performed, including XRD, FTIR and chemical and textural analysis. Electrochemical investigation was performed on a glassy carbon electrode (GCE) support with thin film of homogenously deposited either Na-enriched or one of organomodified clays forming composite electrodes. The behavior of the composite electrodes in the electrooxidation of p-nitrophenol (p-NP) in acidic media was analyzed using multisweep cyclic voltammetry. Oxidation of p-NP occurred at 1.2 V vs. Ag/AgCl for all investigated electrodes. The results indicate that the incorporation of BTMA cations into smectite enhanced the electrode stability toward the electrooxidation of p-NP in comparison to bare GCE and composite electrode based on Na-enriched clay. The current density for the p-NP oxidation wave slightly decreased with the increase of BTMA loading. On the other hand the electrode stability was significantly improved with the increase of BTMA loading. (C) 2014 Elsevier B.V. All rights reserved.

AB  - In this paper, macroporous glycidyl methacrylate and ethylene glycol dimethacrylate copolymer functionalized with diethylene triamine (PGME-deta), was evaluated as Reactive Black 5 (RB5) sorbent. Batch RB5 removal from aqueous solution by PGME-deta was investigated by varying pH, contact time, sorbent dosage, initial dye concentration and temperature. The sorption is pH sensitive having maximum at pH 2 (dye removal of 85%), decreasing with the increase of pH (dye removal of 24% at pH 11) after 60 min. Sorption kinetics was fitted to chemical-reaction and particle-diffusion models (pseudo-first-, pseudo-second-order, intraparticle diffusion and Mckay models). The pseudo-second-order kinetic model accurately predicted the RB5 amount sorbed under all investigated operating conditions, while the intraparticle diffusion was the dominant rate-limiting mechanism. The diffusion mechanism was more prevalent with the decrease in temperature and the increase in concentration. The isotherm data was best fitted with the Langmuir model, indicating homogeneous distribution of active sites on PGME-deta and monolayer sorption, with the maximum sorption capacity of 353 mg g(-1). The calculated sorption rates improved with increasing temperature and an activation energy close to 40 kj mol(-1) was determined, suggesting that chemisorption was also rate-controlling.
AB  - U okviru ovog rada ispitana je mogućnost korišćenja makroporoznog kopolimera glicidilmetakrilata i etilenglikoldimetakrilata funkcionalizovanog reakcijom otvaranja epoksidnih grupa sa dietilentriaminom (PGME-deta) kao sorbenta reaktivne tekstilne boje Reactive Black 5 (RB5). U šaržnim uslovima je ispitano uklanjanje RB5 iz vodenog rastvora pomoću PGME-deta, variranjem pH, vremena kontakta, mase sorbenta, početne koncentracije boje i temperature. PGME-deta je pokazao afinitet za sorpciju RB5 zbog prisustva protonovanih amino grupa koje privlače anjonske sulfonatne grupe u molekulu boje i mogućnosti stvaranja vodoničnih veza između sorbenta i sorbata. Kinetika sorpcije je analizirana pomoću četiri kinetička modela (pseudo-prvog, pseudo-drugog reda, unutarčestične difuzije i Mekej) da bi se odredilo koji model najbolje opisuje sorpciju RB5. Zapažen je izrazit uticaj pH vrednosti na sorpciju RB5, sa maksimumom na pH 2 (pri čemu je efikasnost uklanjanja boje 85%), i smanjenjem količine sorbovane boje sa povećanjem pH (količina uklonjene boje na pH 11 posle 60 min iznosi samo 24%). Izučavanjem kinetike sorpcije pokazalo se da sorpcija RB5 pomoću PGME-deta sledi kinetički model pseudo-drugog reda (PSO), sugerišući da je brzina sorpcije kontrolisana kapacitetom sorbenta i koncentracijom sorbata. Mehanizam procesa dominantno čini unutarčestična difuzija, uz manji uticaj difuzije kroz film. Ovi mehanizmi difuzije su izraženiji pri nižim temperaturama i većim koncentracijama. Langmirov model najbolje opisuje ravnotežnu izotermu, ukazujući na homogenu raspodelu aktivnih mesta na površini PGME-deta i monoslojnu sorpciju. Maksimalni sorpcioni kapacitet izračunat iz Langmirove izoterme iznosi 353 mg g-1. Zapaženo je da se brzina sorpcije povećava sa povećanjem temperature. Izračunata vrednost aktivacione energije od oko 40 kJ mol-1 potvrđuje da se radi o procesu koji dominantno kontroliše hemisorpcija.

AB  - Two series of organobentonites (OBs) were synthesized from Na+-exchanged bentonite clay from Bogovina, Serbia. In the first series the starting material was modified using hexadecyltrimethylammonium (HDTMA(+)) ion in the amounts corresponding to 0.2, 0.5, 1.0 and 2.0 of the CEC value. The second series was obtained using quaternary alkyl ammonium cations (QAACs) with different alkyl chain lengths: hexadecyltrimethylammonium (HDTMA(+)), dodecyltrimethylammonium (DDTMA(+)) and tetramethylammonium (TMA(+)) ions. The synthesized OBs were characterized. The adsorption of anionic reactive dye Reactive Black 5 (RB5) and Pb2+ from single component solutions and their hi-component solution was investigated for both series of OBs. The adsorptive properties of the OBs were correlated to the amount and type of incorporated QAACs. The correlation was tested using different mathematical models and best fits were found. Experimental results showed that simultaneous adsorption of RB5 and Pb2+ exhibited synergic effect. The adsorption capacity for both RB5 and Pb2+ was higher in their hi-component solution than in single-component solutions. These results indicate the creation of new adsorption sites during the simultaneous adsorption.

abstract = "Two series of organobentonites (OBs) were synthesized from Na+-exchanged bentonite clay from Bogovina, Serbia. In the first series the starting material was modified using hexadecyltrimethylammonium (HDTMA(+)) ion in the amounts corresponding to 0.2, 0.5, 1.0 and 2.0 of the CEC value. The second series was obtained using quaternary alkyl ammonium cations (QAACs) with different alkyl chain lengths: hexadecyltrimethylammonium (HDTMA(+)), dodecyltrimethylammonium (DDTMA(+)) and tetramethylammonium (TMA(+)) ions. The synthesized OBs were characterized. The adsorption of anionic reactive dye Reactive Black 5 (RB5) and Pb2+ from single component solutions and their hi-component solution was investigated for both series of OBs. The adsorptive properties of the OBs were correlated to the amount and type of incorporated QAACs. The correlation was tested using different mathematical models and best fits were found. Experimental results showed that simultaneous adsorption of RB5 and Pb2+ exhibited synergic effect. The adsorption capacity for both RB5 and Pb2+ was higher in their hi-component solution than in single-component solutions. These results indicate the creation of new adsorption sites during the simultaneous adsorption.",

AB  - Ovaj rad je posvećen sintezi organobentonita (OB) dobijenih modifikacijom kvaternernim alkilamonijum katjonima (KAAK), karakterizaciji dobijenih uzoraka, ispitivanju njihovih adsorpcionih svojstava prema organskim i neorganskim zagađivačima prisutnim u otpadnim vodama tekstilne industrije, kao i utvrđivanju multifunkcionalnog adsorbensa koji bi usled posedovanja i hidrofilne i organofilne površine uspešno mogao biti upotrebljen prilikom tretmana otpadnih voda kompleksnog sastava  Sintetisani OB dobijeni su od bentonitne gline sa lokaliteta Bogovina (Srbija). Polazni uzorak frakcije <74 μm je najpre Na–izmenjen (Na–B), a zatim modifikovan KAAK jonima. Modifikacijom su dobijene dve serije organobentonita. U prvoj seriji je korišćen heksadeciltrimetilamonijum (HDTMA) bromid, pri čemu količina odgovara vrednostima Kizm=0,2–3,0 (gde je Kizm broj koji pokazuje odnos KAAK jona prema vrednosti kapaicteta katjonske izmene). Druga sereija je dobijena modifikacijom bentonita KAAK različite dužine alkil niza: HDTMA bromidom, dodeciltrimetilamonijum (DDTMA) bromidom i tetrametilamonijum (TMA) bromidom, pri čemu je Kizm=2,0. Dobijeni uzorci su označeni kao 0,2 HDTMA–B, 0,5 HDTMA–B, 1,0 HDTMA–B, 2,0 HDTMA–B, 3,0 HDTMA–B, 2,0 DDTMA–B, 2,0 TMA–B. Ispitivan je uticaj modifikacije na strukturu, teksturalna i adsorpciona svojstva bentonita. Hemijski sastav polaznog bentonita i Na–B je određen standardnom silikatnom analizom, dok je procena udela organske faze kod OB izvršena žarenjem uzoraka na 800°C, čime je potvrđeno prisustvo organske faze čiji udeo raste sa porastom Kizm i sa porastom dužine alkil niza KAAK. Fazni sastav, teksturalna i morfološka svojstva Na–B i uzoraka OB određeni su korišćenjem XRD analize, IC analize, metodom fizisorpcije N2 i SEM mikroskopije. Utvrđeno je da primenjeni postupci modifikacije dovode isključivo do izmene katjona u međulamelarnom sloju smektita, dok modifikacija ne deluje na druge prateće minerale u bentonitu (kvarc, kalcit, feldspat). Kod uzoraka 0,2, 0,5 i 1,0 HDTMA–B na osnovu vrednosti d001 utvrđeno je da dolazi do formiranja monosloja, dvosloja i pseudo-tri molekulskog sloja HDTMA katjona, dok kod uzoraka sa Kizm=1,0-3,0 HDTMA–B unutar međusloja dolazi do formiranja organske faze za koju je pretpostavljeno da je delimično sastavljena od parafinskih slojeva. IC spektri uzoraka OB ukazuju na prisustvo tri nove trake koje potiču od vibracija metilenske grupe, što je još jedna potvrda ugradnje KAAK. Kod svih OB osim 2,0 TMA–B, utvrđeno je da sa povećanjem Kizm i dužine alkil niza KAAK dolazi do značajne promene teksturalnih svojstava u odnosu na polazni Na–B. Uočen je pad specifične površine materijla i prelazak mikro i mezoporoznog materijala u gotovo potpuno neporozan. Sa druge strane, 2,0 TMA–B i Na–B imaju slične teksturalne osobine, što je posledica ugradnje kratkolančanog katjona TMA u obliku „pilara“, a posledica je stvaranje mikroporoznog materijala. Analizom SEM mikrofotografija snimljenih uzoraka analizirane HDTMA serije uočava se da svi izorci zadržavaju slojevitu strukturu filosilikata...
AB  - The synthesis of organo-bentonites (OB) obtained by modification with quaternary alkylammonium cations (QAAC), their characterization and evaluation of their efficiency as adsorbents for organic and inorganic aqueous pollutants was investigated in this work. Particular attention was dedicated to the removal of pollutants from textile industry effluents, and obtainment of a multifunctional adsorbent that incorporates both hydrophilic and hydrophobic surfaces, which can be successfully applied in the purification of wastewaters with complex composition. The synthesized OBs were obtained from smectite containing clay bentonite from Bogovina basin (Serbia). The starting material, consisted of particles with diameters of up to 74μm, was submitted to Na-exchange (Na-B), and subsequent modification with QAAC ions. Two series of OBs were obtained in this manner. The first series was obtained using hexadecyltrimethylammonium (HDTMA) bromide. The amount of introduced HDTMA was expressed as Kexch=0,2–3,0, where the value of Kexch represents the ratio between QAAC ions and the cation exchange capacity of the clay. The second series was obtained by the bentonite modification using QAACs (Kexch=2,0) with different alkyl chain lengths: HDTMA bromide, dodecyltrimethylammonium (DDTMA) bromide and tetramethylammonium (TMA) bromide. The samples were denoted as 0,2 HDTMA–B, 0,5 HDTMA–B, 1,0 HDTMA–B, 2,0 HDTMA–B i 3,0 HDTMA–B, 2,0 DDTMA–B, 2,0 TMA–B. The influence of the modification on the structural, textural and adsorption properties of bentonite was investigated. The chemical compositions of the starting and Na-exchanged bentonite were determined by standard silicate analysis, and the fraction of the organic phase in the samples was estimated after calcination at 800°C. The increasing presence of the organic phase with increased Kexch or QAAC alkyl chain length was confirmed. The phase composition, textural and morphological properties of the Na-B and OB samples were determined by XRD and IR analyses, N2 physisorption and SEM microscopy. It was found that the applied modification procedures resulted in the exclusive exchange of cations from the smectite interlamellar region, with no impact on the accompanying minerals present in bentonite (quartz, calcite, feldspar). In the case of 0,2, 0,5 i 1,0 HDTMA–B samples, it was concluded from the d001 values that the consequence of the modification was the formation of mono-, bi- or pseudotrimolecular HDTMA layers. As for the 1,0–3,0 HDTMA-B samples it is presumed that the formation of organic phase occurred within the interlamellar region, which is probably partially consisted of paraffin layers. The IR spectra of the OBs exhibited the occurrence of three new bands corresponding to methyl group vibrations, which is another proof of the incorporation of QAACs. For all OB samples, except for the 2,0 TMA–B, was established that the increase in the Kexch values and alkyl chain lengths lead to significant changes in the textural properties comparing to those of the starting Na-B material. The decrease in the specific surface was observed, and the starting micro/mesoporous material was turned almost completely nonporous. On the other hand, the 2,0 TMA–B and Na-B exhibited similar textural properties, which is a consequence of the incorporation of short-alkylchained TMA cations in the form of pillars resulting in a microporous material The analysis of the SEM micrographs of the HDTMA sample series it was observed that all the samples retained characteristic phylosilicate layered structure...
