摘要：

The heteropoly acid silverwas prepared by using sodium tungstate, two sodium hydrogen phosphate, sodium vanadate and silver nitrate. The silver polyoxometalate was characterized by IR. The results showed that the synthesized salt had Keggin type structure. A supported heteropoly acid silver catalyst was prepared by hydrolyzing titanium dioxide with titanate four butyl acetate gel as a carrier. In the self-made photocatalytic reactor, the effects of catalyst usage, initial pH of wastewater, concentration of experimental wastewater, catalyst dosage and catalyst repetition efficiency on the decolorization rate of pharmaceutical wastewater were investigated.
