Abstract

Napretkom društva i industrije raste i potrošnja čiste vode te se stvaraju sve veće količine otpadne vode koja je onečišćena raznim organskim i anorganskim tvarima. Mikroonečišćujuće tvari predstavljaju najveću opasnost koja proizlazi od njihovih potencijalnih svojstava da uzrokuju neželjene kemijske reakcije u okolišu koje utječu na zdravlje ljudi. Vrlo ih je teško ili gotovo nemoguće ukloniti standardnim mehaničkim i biološkim procesima. Metode koje bi se mogle upotrebljavati u pročišćavanju otpadnih voda su napredni oksidacijski postupci kao što je fotokataliza. Za proces fotokatalize potrebna je prisutnost fotokatalizatora, a jedan od fotokatalizatora koji se najčešće upotrebljava je TiO2. U ovom radu istraženi su fotokatalizatori koji su pripravljeni nanošenjem TiO2 na karbonska vlakna i sol – gel metodom na staklena vlakna te je ispitan utjecaj na fotokatalitička svojstva.

Abstract (english)

With the progress of society and industry, the consumption of clean water is also increasing, and increasing amounts of waste water are created that are contaminated with various organic and inorganic substances. Micropollutants represent the greatest danger arising from their potential properties to cause unwanted chemical reactions in the environment that affect human health. They are very difficult or almost impossible to remove by standard mechanical and biological processes. Methods that could be used in wastewater treatment are advanced oxidation processes such as photocatalysis. The photocatalysis process requires the presence of a photocatalyst, and one of the photocatalysts used is TiO2. In this work, photocatalysts prepared by applying TiO2 to carbon fibers and by the sol-gel method to glass fibers were investigated, and the influence on the photocatalytic properties was examined.
