摘　　要：采用浸渍法制备了Ti O2负载的光催化剂Si W11/Ti O2,在紫外光照射下,研究了其对模拟染料废水结晶紫溶液的光催化降解的反应,讨论了结晶紫溶液的酸度、溶液的初始质量浓度以及催化剂投加量等对结晶紫溶液脱色效果的影响.结果表明,催化剂加入量为3 mg,结晶紫的初始质量浓度为15 mg/L,p H=6时,脱色率达到87.08%.The SiW11/TiO2 photocatalyst was prepared by supported heteropoly acidon TiO2 via impregnation method.The photocatalytic activities of the composite were tested by photocatalytic degradation of crystal violet under the UV ray.The effects of the catalyst quantity,the initial concentration of the crystal violet and the solution pH value on decolorizing efficiency of the solution were discussed in detail.The results showed thatthe degradation rate of crystal violet with SiW11/TiO2was 87.08% in the solution containing 15 mg/L of crystal violet when the dosage of catalyst was 3 mg and the pH was 6.
