TiO2 powders were prepared by modified sol-gel technique. Methylene Blue (MB), as simulated pollutants, was decomposed by UV and TiO2. The degradation of MB followed pseudo first order kinetics and half life (t1/2) of MB was used to evaluate the degradation speed. Response surface methodology was applied to research the relationship between the half life of MB and preparation conditions. The results showed that half life was increased with the rise of acetyl acetone/ tetrabutyltitanate molar ratio and n-hexanol/TX-100 molar ratio, and the rise of water/Triton X-100 molar ratio almost had no effect on half life of MB. The optimized experimental condition was water/ Triton X-100 molar ratio of 5.32, n-hexanol/TX-100 molar ratio of 7.97 and acetyl acetone/tetrabutyltitanate molar ratio of 0.44 with half life of 5.34 min of predicted value, and the experimented value of half life was 5.52 min, only 3.4% error.Keywords
