Sažetak
Advanced oxidation processes (AOPs) represent a method able to decolorize and to reduce recalcitrant colored wastewater load. Photocatalysis is established as an effective AOP as sustainable water treatment technology offering a perspective for the degradation of many organic water pollutants, converting them to biodegradable compounds or completely mineralizing them into carbon dioxide and water. Titanium dioxide is one of the most important photocatalyst, which is widely used due to its chemical stability and high photocatalytic activity. However, relatively high recombination rate of electron-hole pair in excited. TiO2 restricts its photocatalytic activity thus hindering its practical application in the water treatment processes. Conducting polymers as poly(3, 4- ethylenedioxythiophene) (PEDOT) with extended π-conjugated electron system and satisfactory environmental stability can act as stable photosensitizer to sensitize TiO under solar light irradiation. The objective was to synthesize PEDOT-TiO2 based photocatalysts and to investigate photocatalytic activities under UV/Visible and solar light irradiation using simulated wastewater containing organic azo dye C.I. Reactive Red 45 (RR45) as water pollutant to determine the degradation efficiency in terms of decolorization and total organic carbon (TOC) removal. Photocatalysts were synthesized by oxidative chemical polymerization with two different oxidants, FeCl3 and (NH4 )2 S 2O8at different polymerization conditions (time and temperature).
