Photocatalytic Degradation of Bisphenol A in Wastewater Using Nanometer TiO₂ Film

Abstract:

In this paper, the nanometer TiO₂ film is prepared by sol-gel method, using tetrabutyl titanate as source, ethanol as solvent. A transparent sol aging in air 30min, titanium dioxide films are prepared by using spin coating method. The BPA solution is degraded by the nanometer TiO₂ film. The photocatalytic degradation efficiency is influenced by the initial BPA concentration, the solution pH, irradiation time and the UV irradiation intensity. The short degradation time shows that the nanometer TiO₂ film can be used as an easy and efficient method to degrade the BPA solution.
