Abstract
Otpadne vode raznih preradbenih industrija predstavljaju vrlo velik ekološki problem. U tu svrhu razvijaju se brzi i ekonomični procesi u obradi otpadnih voda, a kao jedan od njih koristi se fotokatalička degradacija organskih komponenti otpadnih voda fotokatalizatorima među kojima se kao vrlo učinkovit pokazao cinkov oksid (ZnO). U ovome radu istraživana je fotokatalitička razgradnju azo bojila Reactive Red 45 uz upotrebu sintetiziranog ZnO ili kompozita ZnO/lebdeći pepeo (ZnO/FA) kao katalizatora. Lebdeći pepeo u kompozitu služi kao nosač katalizatora ZnO. ZnO je sintetiziran pomoću dva različita postupka, a kompozit ZnO/lebdeći pepeo sadrži 16 ili 20 mas% lebdećeg pepela. Rezultati određivanja fotokatalitičke razgradnje pokazuju da najveću fotokatalitičku aktivnost pokazuju uzorci ZnO 1. postupak i ZnO 2. postupak koji se mogu učinkoviti koristiti u tri uzastopna ciklusa fotokatalize.
Abstract (english)
Wastewater from a variety of processing industries is a growing environmental problem in today's world. For this purpose, scientists are developing quick and cost-effective wastewater treatment processes. One of them is the photocatalytic degradation of organic components in wastewater using photocatalysts, among which zinc oxide (ZnO) proved to be highly efficient. This work studies the photocatalytic degradation of azo dye Reactive Red 45 using synthesized ZnO and nanocomposite zinc oxide/fly ash (ZnO/FA) as the catalysts. Fly ash is used as a catalyst carrier in the composite. ZnO is synthesized using two different methods. The nanocomposite zinc oxide/fly ash contains 16 or 20 wt. % of fly ash. The results of photocatalytic degradation show the highest photocatalytic activity using zinc oxyde synthesized according to the first and second procedure that can be used in three consecutive cycles of photocatalysis without losing effectiveness.
