Abstract
Porastom broja stanovništva dolazi do razvoja industrije što uzrokuje veću potrebu za proizvodnjom i uporabom različitih pesticida, farmaceutika i drugih proizvoda, klasificiranih kao mikro onečišćivači koji imaju velik negativan utjecaj na vodeni okoliš. Porast koncentracije mikroonečišćivača u prirodi dovodi do potrebe pronalaska načina u kojem bi iste uklonili ili preveli u bezopasan oblik. Jedna od modernih metoda uklanjanja farmaceutika iz vode dolazi korištenjem naprednih oksidacijskih tehnika, to jest fotokataliza. U ovome radu pripravljeni su fotokatalizatorinanašanjem titan (IV) oksida sa i bez grafen oksida na staklene mrežice sol-gel postupkom te su uspoređena njihova fotokatalitička svojstva. Fotokataliza se provodila u reaktoru s UV lampom te se reakcija pratila kroz degradaciju salicilne kiseline UV/VIS spektrofotometrom.Najbolji rezultati dobiveni su korištenjem čistog titan (IV) oksida bez prisustva grafen oksida. Uspješno nanašenje fotokatalizatora je potvrđeno vizualno i SEM analizom.
Abstract (english)
The increase in population leads to the development of industry, which causes a greater need for the production and use of various pesticides, pharmaceuticals and other products, classified as micro-pollutants than have negative side effects on water ecosystem. The increase in the concentration of micro-pollutants in nature leads to the need for a way in which they would be removed or converted into a harmless form. One of the modern methods of removing pharmaceuticals from water comes by using advanced oxidation techniques, i.e. photocatalysis. In this work photocatalysts were prepared by applying titanium (IV) oxide with and without graphene oxide onto glass fibres with sol-gel process and their photocatalytic properties were compared. Photocatalysis was performed in a reactor with a UV lamp and the reaction was monitored through the degradation of salicylic acid by UV / VIS spectrophotometer. The best results were obtained using pure titanium (IV) oxide without the presence of graphene oxide. Successful photocatalyst application was confirmed visually and by SEM analysis.
