摘　　要：The investigation photocatalytic degradation of three azo dyes solution(Acid Mordant Navy Blue RRN,Acid Mordant Black PV,Acid Mordant Brown RH) under UV light irradiation using the polyoxometalates as catalyst was reported in this article.The research results showed that the photocatalytic activity of Keggin catalyst is higher than that of Dawson,and the catalyst α-H4SiW12O40 had the best efficiency to the photocatalytic decoloration of RRN.In 350 mg·L-1(30 mL) RRN solution,the optimum reaction condition was as follow:the amount of catalyst α-H4SiW12O40 is 75 μmol·L-1,V(methanol)=3.0 mL,pH=3.0.Under the above condition,the decolorization rate of RRN at 40 minutes comes up to 98.66%.
