Degradation of 4-Chlorophenol in Wastewater Using Nanometer TiO2 Film under UV Light Irradiation
In this paper, using tetrabutyl titanate as source, H2O2(30%) as solvent, synthesis of titanium dioxide sol was achieved by sol-gel method. A transparent sol aging in air 30min, titanium dioxide films were prepared by using spin coating method. The photodegradation capability of 4-chlorophenol has been enhanced by using immobilized TiO2 particles, where the titanium sol synthesized by a sol-gel method was used as the binder for the immobilization. Optimal conditions of TiO2 film, 4-chlorophenol concentration, solution pH, and UV irradiation intensity have been found to enhance the photodegradation efficiency.
