Photocatalytic Degradation of Bromophenol Blue Solution Using Nanometer TiO2

Abstract

Titanium tetrachloride with inorganic salts as raw materials in the experiment, TiO2is prepared by the hydrolyzation method in (NH4)2SO4-modified TiCl4solution, the maximal photocatalytic activity is observed at the mole ratio of TiCl4: (NH4)2SO4=1:2, the water-bath temperature of 90°C. Bromophenol blue solution is degraded by the nanometer TiO2. The photocatalytic degradation efficiency is influenced by the nanometer TiO2amount, irradiation time, the UV irradiation intensity and solution temperature. The short degradation time shows that the nanometer TiO2can be used as an easy and efficient method to degrade bromophenol blue solution.
