| Abstract: | H3PW12O40/SiO2 was synthesize from tetraethyl orthosilicate,butyl alcohol,12-tungstenphosphate and deionized water and its photocatalytic degradation activity for dye wastewater was tested.The effect of the type of dyes,pH value of wastewater,the dosages of catalyst and irradiation time on the degradation rate was studied.The results indicated that the decoloration effect of H3PW12O40/SiO2 on dye solutions was prominent.The decolorization rate of active bright red X-3B and direct scarlet 4BS's were 80% and 74%,respectively.Different dye solutions had different optimal conditions of decoloration. |
