| 摘 要： | 以硅钨酸为催化剂光催化降解煮绿染料溶液.对溶液的pH值,催化剂的投加量,溶液的初始浓度及紫外光灯的强度对脱色效果的影响进行了研究.实验结果表明:溶液的pH值、催化剂的投加量、溶液的初始浓度及紫外光灯的强度对煮绿染料溶液的光催化脱色效率都有一定的影响.当煮绿染料溶液的初始浓度为10 mg/L,溶液的pH为1,硅钨酸浓度0.6 g/L,在高度为13.2 cm的紫外灯辐射下,降解率最高可达到42.8%.

| Abstract: | The silicotungstic acid was used as the photocatalyst to degrade boiling-green solution under ultraviolet radiation.The effects of the solution pH,catalyst quantity,initial concentration of the solution and the irradiation intensity on the degradation were discussed in detail.The results show that these factors have a certain effect on the decolour rate of the boilin-green solution.Under the experimental condition,when the initial concentration of the solution is 10 mg/L,the solution pH value is 1,the catalyst quantity is 0.6 g/L,and the distance between the solution and the light source is 13.2 cm,the degradation efficiency can reach up to 42.8%. |
