Photocatalytic Degradation of Bromophenol Blue Solution Using Nanometer TiO₂

Abstract:

Titanium tetrachloride with inorganic salts as raw materials in the experiment, TiO₂ is prepared by the hydrolyzation method in (NH₄)₂SO₄-modified TiCl₄ solution, 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 TiO₂ amount, irradiation time, the UV irradiation intensity and solution temperature. The short degradation time shows that the nanometer TiO₂ can be used as an easy and efficient method to degrade bromophenol blue solution.
