杂多酸盐/聚苯胺/TiO_2复合材料光催化降解甲基橙

Photocatalytic Degradation of Methyl Orange by Composite Materials Heteropolytungstate/PANI/TiO_2

以PW11Ti/PANI/TiO2为光催化剂,在太阳光照射下,研究了模拟染料废水甲基橙溶液的光催化降解的反应,讨论了甲基橙溶液的酸度、溶液的初始浓度以及催化剂投加量等对甲基橙溶液脱色效果的影响。结果表明:催化剂加入量为10 mg,甲基橙的初始浓度为20 mg/L,pH=4,脱色率达到85.62%。

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.
