Abstract
The titanium dioxide(TiO2) doped with Fe3+or Cu2+was prepared by sol-gel method. Their photocatalytic activities for photodegradation of mordant blue wastewater were investigated under the natural light irradiation condition. The results showed that photocatalytic activity of TiO2doped with Fe3+or Cu2+was better than pure TiO2, and the TiO2doped with Fe3+was the best. The efficiency of photocatalytic degradation reached the optimum value when doping ratio of Fe3+was 0.1% and its dosage was 0.5g/L, the degradation rate reached 93.5%. When doping ratio of Cu2+was 3% and its dosage was 0.6g/L, the degradation rate reached 83.6%.
