PMoV_2/PANI/TiO_2光催化降解染料废水的研究

Studies on photocatalytic degradation of dye wastewater with PMoV_2/PANI/TiO_2

以PMoV2/PANI/TiO2为催化剂,在紫外灯辐射下,研究了模拟染料废水龙胆紫溶液的光催化降解反应,讨论了催化剂投加量、龙胆紫溶液的初始质量浓度、酸度等对催化脱色效果的影响.结果表明,50 mL的龙胆紫溶液在紫外灯辐射下最佳的质量浓度为5 mg/L,催化剂用量为0.005 0 g,溶液酸度为pH=4;降解率达93.0%.

The PMoV2/PANI/TiO2was researched as the photocatalyst to degradation of the crystal violet in solution under the UV ray.The effects of the catalyst quantity,the initial concentration of the crystal violet and the solution pH on decolorizing efficiency of the solution were discussed in detail.The results of the experimentation show the optimum catalytic conditions are that the concentration of the 50 mL crystal violet is 5 mg/L,the amount of catalyst is 0.005 0 g and the pH value of the solution is 4 with ultraviolet radiation,the decoloration rate of methyl violet achieved 93.0%.
