Degradation of Congo Red in Wastewater Using Nanometer TiO₂ Film under UV Light Irradiation

Abstract:

Synthesis of titanium dioxide sol was prepared by sol-gel method, using tetrabutyl titanate as source, ethanol as solvent, acetic acid as complexing agent. A transparent sol aging in air 30min, titanium dioxide films were prepared by using spin coating method. Congo red degradation was investigated by TiO₂ photocatalysis. Study the efficiency of decolorization was influenced by the coating times, heat-treated time, the initial concentration of congo red and solution pH.
