| Abstract: | The PW12/PANI/ZnO was researched as the photocatalyst to degradation of the methylene blue in solution under the UV ray. The influences of several operating parameters, such as the dosage of catalyst, initial dye concentration and pH on the photocatalytic degradation of methylene blue were investigated. The degradation rate of methylene blue was 85.84% with concentration 5 mg/L, PW12/PANI/ZnO 0. 012 5 g, pH =3 and 30 W ultraviolet light, and irradiation for 90 min. |
