Abstract
U okviru ovog istraživanja sintetiziran je nanokompozitni fotokatalizaor TiO2-BiVO4 za uklanjanje farmaceutika diklofenaka i karbamazepina iz otpadne vode. Diklofenak je nesteroidni, protuupalni lijek, a karbamazepin se upotrebljava kao anelgetik i antikonvulziv. Zbog njihove česte upotrebe akumuliraju se u okolišu i predstavljaju rizik za ekosustav. Kako bi se smanjilo onečišćenje ovim farmaceuticima, potrebno je razvijati metode njihovog uklanjanja, a heterogena fotokataliza jedna je od obećavajućih naprednih oksidacijskih tehnologija u području rješavanja navedene problematike. Pripremljeno je šest fotokatalizatora s različitim udjelima BiVO4. Tri fotokatalizatora sintetizirana su sol-gel sintezom, a preostala tri hidrotermalnom sintezom. Za opis mehanizama adsorpcije farmaceutika na površinu fotokatalizatora korišteni su Langmuirov i Freundlichov izotermni model. Procjena sorpcijskih svojstava fotokatalizatora te određivanje lakoće adsorpcije željenih iona iz onečišćujućih tvari provedeno je određivanjem pHPZC površine. Do najbolje adsorpcije DCF-a dolazi pri pH 4, neovisno o metodi sinteze. Dobiveni rezultati upućuju na višeslojnu adsorpciju i Freundlichov izotermni model. Pri pH 6 adsorpcija DCF-a bitno je oslabljena, dok pH 8 nije prisutna. Do adsorpcije CBZ-a nije došlo u ispitivanim uvjetima.
Abstract (english)
Within this study, nanocomposite photocatalyst TiO2-BiVO4 for removing pharmaceuticals diclofenac and carbamazepine from wastewater was synthesized. Diclofenac is a nonsteroidal, anti-inflammatory drug, and carbamazepine is used as analgesic and anticonvulsant. Frequent use of these pharmaceuticals caused their accumulation in the environment and they pose a risk for the ecosystem. To reduce pollution with these pharmaceuticals, it is necessary to develop removing methods, and heterogeneous photocatalysis is one of the promising advanced oxidation techniques for this problem solving. Six photocatalysts with different ratios of BiVO4 were prepared. Three photocatalysts were prepared by sol-gel synthesis, and remaining three by hydrothermal synthesis. Langmuir and Freundlich's isothermal model were used for describing the mechanism of adsorption. Estimation of photocatalyst sorption features and adsorption of target ions from pollutants were carried out by determination of pHPZC surface. The best adsorption of DCF is present at pH 4, for both syntheses. Results refer to multilayer adsorption and Freundlich isothermal model. A pH 6 adsorption of DCF is weakened, and at pH 8 is not present. CBZ adsorption did not occur under the given conditions.
