| Abstract: | Photodegradation of disperse dyes solution using semiconductor TiO2 as catalyst has been studied. Under blowing air condition, after 50 min irradiation, it was found that disperse dyes solution of 50 mg/l has been completely decoloured, and the removal rate of COD was over 70%. Effects of air, pH, lamp distance and reuse of TiO2 on degradation were also discussed. |
