Photocatalytic Degradation of Cresol Red in Wastewater Using Nanometer TiO₂

Abstract:

In this paper, 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. The photocatalytic degradation efficiency is influenced by the initial cresol red concentration, the solution pH, irradiation time and the UV irradiation intensity. The short degradation time shows that the nanometer TiO₂ can be used as an easy and efficient method to degrade the cresol red solution in wastewater.
