| Abstract: | The PWHTi/PANI/TiO2 was researched as the photocatalyst to degradation of methyl orange in solution under the sun light ray. The effects of the initial concentration of the methyl orange, the catalyst quantity and the solution pH on deeolorizing efficiency of the solution were discussed in detail. The degradation rate of methyl orange with PW11Ti/ PANI/TiO= was 85.62% after being treated for 150 min under the sun light irradiation at pH =4, using 20 mg/L. |
