摘要
利用半导体光催化氧化法 ,对影响活性艳蓝K 3R和活性翠蓝K GR两种非偶氮染料的光降解率的因素———催化剂TiO2 用量、染料初始浓度、H2 O2 用量、溶液初始 pH值以及光照时间进行了研究 ,找出了最佳的反应条件。在最佳反应条件下 ,降解该 2种染料废水 ,其出水色度均低于5 0 。
Employing semi conductor photocatalytic oxidization technique, I have studied the factors affecting the photo degradation rate of a couple of negate azo dye stuff-activity yan blue and activity cui blue,including TiO 2 quantity, virgin concentration of the dye, H 2O 2 quantity, the solution's virgin pH and the light perdurbility. Then optimum reaction is determined. Color degrees of the two dyes treated under this condition are below 50,fulfilling the National Standard for discharging.
