摘　　要：采用浸渍法和微波法相结合,制备了负载型杂多酸光催化剂HH3PMo12O40/SiO2。在紫外光照射下,研究了其对模拟染料废水酸性蓝溶液的光催化降解的影响。结果表明,H3PMo12O40/SiO2比单独的H3PMo12O40/SiO2光催化性能要好,当初始浓度为10mg/l酸性蓝溶液,H3PMo12O40/SiO2(WH3PMo12O40:WSiO2=1:3)投加量为90mg/l,pH=1.00,H2O2(30%)10ml/l,150min脱色率就可达95.77%。H3PMo12O40/SiO2 photocatalysts were prepared by impregnation and microwave method . Experiments of photocatalyic degradation of acid blue were carried out to evaluate the photocatalytic activity of H3PMo12O40/SiO2 with ultraviolet radiation. The result shows that H3PMo12O40/SiO2 is higher than the activity of pure H3PMo12O40, When the initial concentration of acid blue is 10mg/l, the added amount of photocatalyst （ WH3PMO12O40： WSiO2 = 1 ： 3 ） is 90mg/l, and H2O2 （30 % ） is 10ml/l, pH = 1.00, after 150 minutes, the degradation percentage of acid blue is 95.77 % .
