摘要
本文研究了以沉淀法制备的TiO2 为催化剂 ,紫外杀菌灯为光源 ,对阳离子艳红染料进行光催化降解的可行性。结果表明 ,在实验条件下 ,本系统对阳离子艳红染料有明显的降解效果。浓度为 10mg/L的阳离子艳红染料经过 3 0min的处理 ,其降解率 >88%。此外 ,还探讨了溶液初始 pH值、催化剂的投加量。
It was studied that the degradation of cation dye with TiO 2 photo catalyst prepared by precipitation method, using ultraviolet lamp as light source. The results showed, under experimental conditions, that the system had marked degration effect for cation dye. The concentration reducing content of cation dye with the concentration of 10 mg/L was more than 88% in 30 minutes. Besides, we discussed the effect of pH value, the amount of catalyst, height of liquid, light distance for the degradation.
