AB  - Poslednjih godina velika pažnja se poklanja prečišćavanju otpadnih voda, koje u vodene
ekosisteme unose niz različitih zagađujućih materija. Za uklanjanje organskih zagađujućih materija
standardno se koriste različite fizičko-hemijske i biološke metode, kao što su filtracija, koagulacija,
flokulacija, jonska izmena i fotokatalitička razgradnja. Međutim, efikasnost ovih metoda je često
nezadovoljavajuća usled njihove visoke cene kao i velike količine toksičnih i kancerogenih
nusprodukata koji njihovom primenom mogu nastati. Jedna od najekonomičnijih, najpouzdanijih i
najefikasnijih metoda je adsorpcija. U ovom radu korišćeni su kompozitni ugljenični materijali
dobijeni hidrotermalnom karbonizacijom, polazeći od glukoze, titan izopropoksida i melamina, kao
izvora ugljenika, titana i azota. Variranjem količine melamina u reakcionoj smeši, dobijeni su
kompozitni materijali različitih karakteristika. Ispitan je uticaj količine melamina na specifičnu
površinu materijala, prisustvo površinskih funkcionlanih grupa i adsorpcione karakteristike.
Adsorpcione karakteristike dobijenih materijala ispitane su adsorpcijom metilensko-plavog, kao
modela organske zagađujuće materije. Dobijeni rezultati pokazuju da adsorpcioni proces prati
kinetiku pseudo-drugog reda i može se opisati Lengmirovom adsorpcionom izotermom. Takođe,
količina melamina dodata u reakcionu smešu utiče na adsorpcione karakteristike u smislu da
najmanja količina dodatog melamina daje materijal sa najboljim adsorpcionim kapacitetom.

AB  - Photocatalytic degradation of the methomyl pesticide in aqueous suspension
of TiO2 using an Osram ultra-vitalux® lamp (315-400 nm) was investigated.
The effect of parameters such as initial concentration of catalyst, initial
methomyl concentration, and pH were studied. Complete removal of
methomyl was achieved but mineralization of organic carbon was
incomplete indicating the formation of methomyl degradation products.
Liquid chromatography tandem mass spectrometry technique was used in
order to identify the methomyl degradation products and three major
degradation products have been identified.

AB  - Cilj ovog rada bio je ispitivanje načina adsorpcije i raspodele odabranih lekova i pesticida između vodene faze i sedimenta, kao i određivanje stepena adsorpcije i desorpcije na sedimentu reke Dunav. Rezultati adsorpcije leka karbamazepina i pesticida atrazina, karbendazima i karbofurana pokazuju najbolje slaganje sa Frojndlihovom izotermom, što ukazuje na reverzibilnu adsorpciju. Zbog visokog procenta desorpcije karbamazepina, atrazina i karbendazima, njihovo prisustvo u sistemu voda-sediment je očekivano, dok se karbofuran očekuje u manjoj koncentraciji u vodi, zbog nižeg procenta desorpcije. Lengmirov model opisuje monoslojnu adsorpciju pesticida dimetoata. Ovaj pesticid pokazuje i mali stepen desorpcije, što ukazuje na to da se može akumulirati u sedimentima u visokoj koncentraciji. Adsorpcija lekova trimetoprima, metoprolola i lorazepama se može opisati linearnim modelom. Ovi analiti pokazuju veliki afinitet adsorpcije i mogu se vezati za sediment u koncentracijama većim od ispitivanih. Za razliku od metoprolola i lorazepama, trimetoprim se u velikom procentu desorbuje sa sedimenta, pa se ovaj analit očekuje u vodi. Lekovi bromazepam, eritromicin i amlodipin su pokazali skoro potpunu adsorpciju na sedimentu i veoma mali stepen desorpcije, pa je njihova akumulacija u sedimentima očekivana.
AB  - The aim of this study was investigation of the adsorption and distribution of the selected
pharmaceuticals and pesticides between water phase and sediment, as well as determination
of the adsorption and desorption extent using sediment of the Danube River. Adsorption
data of the drug carbamazepine and pesticides atrazine, carbendazim and carbofuran fit well
to Freundlich isotherm, implying reversible adsorption. Due to high desorption extent of
carbamazepine, atrazine and carbendazim, their presence in water-sediment system is
expected, whereas lower desorption level of carbofuran indicates lower expected
concentration of this pesticide in water. Langmuir model describes monolayer adsorption of
pesticide dimethoate. This pesticide also shows low desorption extent, indicating its high
accumulation in sediments. Adsorption data of pharmaceuticals trimethoprim, metoprolol
and lorazepam fit fine to the linear model. These analytes show high adsorption affinity and
can be adsorbed onto sediment at concentrations higher than tested. Unlike metoprolol and
lorazepam, trimethoprim exhibits higher desorption level, so it is expected in water.
Pharmaceuticals bromazepam, erythromycin and amlodipine displayed almost complete
adsorption onto sediment and extremely low desorption rate, so their accumulation in
sediments is expected.

AB  - The aim of this work was development of sensitive analytical method for determination of drug anisomycin in different tissue samples. The optimized extraction procedure included methanol as extraction solvent and Oasis HLB as extract clean up cartridge. In the method validation, ani-somycin was efficiently extracted from most of tissues, such as heart, brain, spleen, kidney and li-ver, whereas lower recoveries were obtained for fat tissue. Low limits of detection (0.6–3.8 ng g–1) and quantification (2.4–11.8 ng g–1) indicate that developed method is suitable for determination of anisomycin trace levels. The method was linear (R2 > 0.975) in the tested concentration range (50–2500 ng g–1). Significant matrix effect was eliminated using matrix-matched standards. It was finally determined that the developed method is sensitive and reliable for determination of drug anisomycin in various tissue samples using liquid chromatography–tandem mass spectrometry.
AB  - Cilj ovog rada bio je razvoj osetljive analitičke metode za određivanje leka anizomicina u različitim tkivima. U
optimizovanoj proceduri ekstrakcije, metanol je odabran kao rastvarač za ekstrakciju, a Oasis HLB kao
kertridž za prečišćavanje ekstrakta. Prilikom validacije razvijene metode, anizomicin je efikasno ekstrahovan
iz većine tkiva, kao što su srce, mozak, slezina, bubrezi i jetra, dok su za masno tkivo dobijeni niži prinosi.
Niske granice detekcije (0,6–3,8 ng g
–1
) i kvantifikacije (2,4–11,8 ng g–1
) ukazuju da je razvijena metoda
pogodna za određivanje tragova anizomicina. U ispitivanom opsegu koncentracija (50–2500 ng g–1
) metoda je
linearna (R2
> 0,975). Značajan uticaj matrice eliminisan je upotrebom standarda koji odgovaraju matrici
uzorka. Na osnovu rezultata validacije utvrđeno je da je razvijena metoda osetljiva i pouzdana za određivanje
leka anizomicina u različitim tkivima korišćenjem tečne hromatografije sa tandem masenom spektrometrijom.

The method was linear (R2 > 0.975) in the tested concentration range (50–2500 ng g–1). Significant matrix effect was eliminated using matrix-matched standards. It was finally determined that the developed method is sensitive and reliable for determination of drug anisomycin in various tissue samples using liquid chromatography–tandem mass spectrometry., Cilj ovog rada bio je razvoj osetljive analitičke metode za određivanje leka anizomicina u različitim tkivima. U
optimizovanoj proceduri ekstrakcije, metanol je odabran kao rastvarač za ekstrakciju, a Oasis HLB kao
kertridž za prečišćavanje ekstrakta. Prilikom validacije razvijene metode, anizomicin je efikasno ekstrahovan
iz većine tkiva, kao što su srce, mozak, slezina, bubrezi i jetra, dok su za masno tkivo dobijeni niži prinosi.
Niske granice detekcije (0,6–3,8 ng g
–1
) i kvantifikacije (2,4–11,8 ng g–1
) ukazuju da je razvijena metoda
pogodna za određivanje tragova anizomicina. U ispitivanom opsegu koncentracija (50–2500 ng g–1
) metoda je
linearna (R2
> 0,975). Značajan uticaj matrice eliminisan je upotrebom standarda koji odgovaraju matrici
uzorka. Na osnovu rezultata validacije utvrđeno je da je razvijena metoda osetljiva i pouzdana za određivanje
leka anizomicina u različitim tkivima korišćenjem tečne hromatografije sa tandem masenom spektrometrijom.",

AB  - Glassy carbon plates were irradiated with 15 key H(+) ion-beam in the fluence range of 1 x 10(16)-3 x 10(18) ion cm(-2). The influence of ion irradiation on surface morphology and topology was examined by scanning electron and atomic force microscopy. Structural changes were monitored by Raman spectrometry, while changes of wettability and the content of surface oxygen complexes were examined by contact angle measurements and temperature programmed desorption. Elastic recoil detection analysis was applied for determination of hydrogen concentration profiles in irradiated samples. Cyclic voltammetry was used for the assessment of the electrochemical properties of modified glassy carbon electrodes. It was concluded that there is critical fluence range (2 x 10(17)-5 x 10(17) ion cm(-2)) inside of which significant changes of glassy carbon properties occur.

AB  - Boron was introduced into glassy carbon by chemical modification and by irradiating the precursor polymer with boron ions. Using chemical modification, a polymer with uniform distribution of boron in the bulk was obtained, whereas irradiation with B3+ produced a polymer with boron located in a narrow region under the surface. Following modification with boron, the samples were carbonized at 1273 K and examined using X-ray diffraction, Raman spectroscopy, temperature programmed desorption (TPD) and by hardness measurements. Structural analysis results suggest that boron is mostly substitutionally bonded in the glassy carbon structure regardless of the method used to introduce boron into the polymer precursor. Formation of crosslinks between glassy carbon ribbons during carbonization as a consequence of the recombination of ion beam induced changes in the polymer structure and a high concentration of boron in the subsurface layer is proposed to account for an increase of glassy carbon hardness. An increase in the total amount of surface oxygen groups was observed in the TPD spectra of both boron-modified samples due to an increase in the number of active sites. Results show that the nature of these sites is influenced by the initial distribution of boron in the polymer precursor. (C) 2011 Elsevier Ltd. All rights reserved.

AB  - An optimised extraction and cleanup method for the analysis of pesticide in natural water samples is presented. Sixteen pesticides of different polarity and from the different chemical classes (organophosphates, triazines, benzimidazoles, carbamates, carbamides, neonicotinoides, methylureas, phenylureas and benzohydrazides), most frequently used in Serbia, were selected for the analysis. Liquid-phase microextraction in a single hollow fibre (HF-LPME) has been applied for sample preparation. The concentrations of pesticides were determined using HPLC-MS/MS method with electrospray ionisation. The extraction behaviour and selection of the experimental conditions was predicted based on log D and pK (a) values of targeted pesticides, which were calculated applying the computer software ACD/Labs PhysChem Suite v12. The influence of the donor pH and concentration of pesticides, organic phase composition as well as the extraction time on the extraction efficiency was investigated. Optimum extraction conditions were evaluated with respect to the investigated parameters of the extraction. The extraction method was validated for 10 out of 16 studied pesticides. Linear range of the pesticides was 0.1-5 A mu g L(-1) with the correlation coefficient from 0.991 to 0.9998, and the relative standard deviation for three standard measurements was between 0.2 and 11.8%. The limits of detections ranged from 0.026 to 0.237 A mu g L(-1) and the limits of quantifications from 0.094 to 0.793 A mu g L(-1). The optimised two-phase HF-LPME method was successfully applied for determination of moderately polar as well low-polar pesticides in the environmental water samples.

AB  - Surface properties of activated carbons have shown to play an important role in
adsorption process. The presence of various functional groups (such as phenolic, carbonyl,
carboxylic) on the carbon surface depends on the nature of its base component and the activation
technique employed in the manufacturing process.
The aim of this work is to gain a better fundamental understanding of the nature of
surface oxide sites present on activated carbon cloth surface (ACC), and their role in the
adsorption process. BET surface areas of ACC were measured by means of benzene adsorption
isotherms. The amount and the type of surface oxygen groups were determined by
thermogravimetric analysis and classical titration following Boehm’s method. Batch adsorption
tests were used to evaluate equilibrium adsorption isotherms of phenol on ACC.
It was shown that both surface area and surface groups composition had impact on adsorption
properties of ACC against phenol.
