摘　　要：文章以Ti(SO4)2、Na2CO3和SnCl4为原料,在超声振动下发生共沉淀反应,经离心分离,干燥,焙烧,制备了SnO2/TiO2复合光催化剂。在高压汞灯照射和搅拌下,以靛蓝胭脂红水溶液为模拟污染物进行光降解实验,实验发现SnO2/TiO2有较好的光催化活性,当掺锡为1%时,靛蓝胭脂红的降解率能达到91%。SnO2/TiO2 compound oxides were prepared by co-precipitation method using Ti（SO4）2, Na2CO3 and SnCI4 as raw material. Indigo carmine taken as pollutant simulation was irradiated with mechanical agitation under high-pressure mercury lamp. It was discovered that the SnO2/TiO2 prepared in the experiment had good light catalyze activeness, and which prepared with 5.0 % stannum doped can degrade indigo carmine to 91.0 %.
