摘　　要：采用水热法制备BiOIO_(3)/硫铟化物复合催化剂,并将其用于水体中Cr(Ⅵ)的去除,研究结果显示:与其他复合材料相比,所制备的BiOIO_(3)/ZnIn_(2)S_(4)对Cr(Ⅵ)具有最佳的光催化活性。而后考察了反应时间、污染物初始浓度、催化剂用量等实验条件对Cr(Ⅵ)去除率的影响。为光催化还原Cr(Ⅵ)的实际应用提供了理论依据。BiOIO_(3)/sulfide-indium compound composite catalyst was prepared by hydrothermal method and used for the removal of Cr(Ⅵ)in water.The results showed that the prepared BiOIO_(3)/ZnIn_(2)S_(4) had the best photocatalytic activity for Cr(Ⅵ)compared with other composite materials.The effects of reaction time,initial concentration of pollutants,catalyst dosage and other experimental conditions on the removal rate of Cr(VI)were investigated.It provides a theoretical basis for the practical application of photocatalytic reduction of Cr(Ⅵ).
