以α-SiW11Ti/PANI/TiO2为光催化剂。在紫外灯辐射下,研究了模拟染料废水孔雀石绿溶液的光催化降解的反应,考察了催化剂投加量、底物浓度、pH值对孔雀石绿降解率的影响。结果表明,孔雀石绿溶液光催化降解的最佳条件为:pH=11,α-SiW11Ti/PANI/TiO2催化剂投加量为0.125 g.L-1,浓度为10 mg.L-1,经30 W紫外灯照射90 min后,其降解率为97.53%。
Photocatalytic Activity of α-SiW_(11)Ti/Polyaniline/TiO_2 Composite Material
The α-SiW11Ti/PANI/TiO2 was researched as the photocatalyst to degradation of the malachite green in solution under the UV ray.The influences of several operating parameters,such as the dosage of catalyst,initialdye concentration and pH on the photocatalytic degradation of MG were investigated.The degradation rate of MG With α-SiW11Ti/PANI/TiO2 was 97.53% after being treated for 90 min under 30 W ultraviolet light irradiation at pH=11,using 0.125 g·L-1.
