摘要
以主波长为 2 5 4 nm的紫外光灯为光源 ,Ti O2 为光催化剂 ,对苯二酚和五氯酚钠混合废水的光催化降解。研究了各种因素如催化剂的活化温度、Ti O2 的用量、溶液的初始浓度以及酸度对降解率的影响。
The photocatalytic degradation of the mixture of p-benzenediol and sodium pentachlorophenate (Na-PCP) in aqueous TiO_2 dispersions under radiation with UV lamp were investigated. TiO_2 powder prepared in 500℃ of activation temperature had better photocatalytic activity. The influence factors, such as pH, solution concentration, dosage of catalyzer on mixture waste water, were discussed. The ultraviolet irradiation spectroscopy showed the photoctalytic degradation mechanisms of the waste water.
