AB  - Carbon materials of different structural and textural properties (multi-walled carbon nanotubes, carbon cryogel, and carbonized hydrothermal carbon) were used as adsorbents for the removal of estrone, 17 beta-estradiol, and 17 alpha-ethinylestradiol from aqueous solutions. Chemical modification and/or activation were applied to alter surface characteristics and to increase the adsorption and desorption efficiency of carbon materials. Surfaces of treated and untreated carbon materials were characterized through the examination of the textural properties, the nature of surface functional groups, and surface acidity. It was found that the adsorption capacity of tested carbon materials is not directly proportional to the specific surface area and the content of surface oxygen groups. However, a high ratio of surface mesoporosity affected the adsorption process most prominently, by increasing adsorption capacity and the rate of the adsorption process. Adsorption of estrone, 17 beta-estradiol, and 17 alpha-ethinylestradiol followed pseudo-second-order kinetic model, while the equilibrium adsorption data were best fitted with the Langmuir isotherm model. Calculated mean adsorption energy values, along with the thermodynamic parameters, indicated that removal of selected hormones was dominated by the physisorption mechanism. High values of adsorption efficiency (88-100 %) and Langmuir adsorption capacities (29.45-194.7 mg/g) imply that examined materials, especially mesoporous carbon cryogel and multi-walled carbon nanotubes, can be used as powerful adsorbents for relatively fast removal of estrogen hormones from water.

AB  - Unappropriated disposing of unused drugs leads to an increase in their concentration in the
environment. Furthermore, wastewater treatment plants are not sufficient to prevent the
transport of drugs. Microplastics (MPs), which are also recognized as important pollutants,
can be divided into primary and secondary. The primary MPs are produced for commercial
purposes, while the secondary MPs are formed by the decomposition of plastic residues.
The hydrophobic nature and large specific surface area of MPs facilitate pollutants
binding. Animals misunderstand MPs for food and consume it, which could have harmful
health impacts because both MPs and adsorbed pollutants are ingested. In this paper, the
adsorption of the selected drugs - azithromycin, carbamazepine, sulfamethoxazole, and
diclofenac on low-density polyethylene (LDPE), polyamide (PA), and poly(ethylene
terephthalate) (PET) microplastics are presented. The experiment showed that drugs bind
best to PA and that azithromycin has the highest binding affinity.
AB  - Neadekvatno odlaganje neiskorišcenih lekova dovodi do povecanja njihove koncentracije u
životnoj sredini. Pored toga, postrojenja za precišcavanje otpadnih voda nisu dovoljna
barijera za sprecavanje transporta lekova. Mikroplastika (MP), koja je tako e detektovana
kao bitan polutant, može se podeliti na primarnu i sekundarnu. Primarna se proizvodi za
komercijalne svrhe, a sekundarna nastaje razgradnjom plasticnih ostataka. Hidrofobna
priroda i velika specificna površina MP olakšava adsorpciju polutanata na ove materijale.
Životinje mešaju MP sa hranom i unose je u svoj organizam, što može imati negativni
uticaj na njihovo zdravlje, jer se tako unose i MP i adsorbovani polutanti. U ovom radu je
prikazana adsorpcija odabranih lekova - azitromicina, karbamazepina, sulfametoksazola i
diklofenaka na sledecim vrstama mikroplastike - polietilenu niske gustine (LDPE),
poliamidu (PA) i poli(etilen tereftalatu) (PET). Eksperiment je pokazao da se lekovi
najbolje vezuju za PA, kao i da azitromicin ima najveci afinitet vezivanja.

AB  - U ovom radu vršena je adsorpcija estrogenih hormona (estrona, 17β-estradiola i
17α-etinilestradiola) na različitim ugljeničnim materijalima, u cilju ispitivanja primenljivosti ovih
materijala za uklanjanje estrogenih hormona iz vode. Materijali korišćeni u eksperimentalnom delu
ovog rada bili su hemijski modifikovani i nemodifikovani karbon kriogel i ugljenične nanocevi, kao
i aktivirani i neaktivirani hidrotermalni ugljenik i aktivirane ugljenične tkanine. Hemijska
modifikacija materijala vršena je pomoću KOH, HNO3 ili HCl. Na osnovu eksperimentalnih
podataka ispitana je kinetika adsopcije, konstruisane su adsorpcione izoterme i upoređene sa
teorijskim modelima. Vršena je i desorpcija hormona, da bi se ispitala mogućnost regeneracije
adsorbenta. Koncentracija ispitivanih hormona u rastvoru nakon adsorpcije određena je metodom
tečne hromatografije - tandem masene spektrometrije. Karakterizacija površine ugljeničnih
materijala vršena je primenom BET metode, kao i određivanjem pH-vrednosti vodenih suspenzija
materijala, merenih nakon dostizanja ravnoteže (engl. pH slurry). Najveća efikasnost adsorpcije
postignuta je na nemodifikovanim ugljeničnim nanocevima, dok su u pogledu desorpcije najbolje
rezultate pokazale ugljenične nanocevi modifikovane sa KOH.
