摘　　要：以Ce4+为氧化剂对酸性黑10B水溶性染料模拟废水进行脱色处理,研究了各种反应条件对脱色率的影响,并且对脱色反应机理进行了分析。结果表明:在染料的初始质量浓度为10 mg/L,pH=1,Ce(SO4)2.4H2O投加量为80 mg/L,紫外灯光照,反应时间为120 min的条件下,脱色率可达到97%。说明以Ce4+为氧化剂对酸性黑10B水溶性染料具有很好的脱色效果,且脱色速率快,药品用量少,成本低,安全无毒,在废水处理上有较大的应用前景。此外,研究发现:紫外灯照射可大大提高脱色速率,缩短脱色时间。The decolorizing rate of the dye,acidic black 10B,wastewater with Ce^4＋ as oxidant has been studied, and the effects of various factors on the decolorizing rate of the dye have been investigated. The results show that the appropriate conditions are as follows ：pH=1, C e （SO4）2·4H2O 80 mg/L,t = 120 rain,illuminated by ultraviolet radiation when the initial concentration of the dye is 10 mg/L When the reacting time is 120 min,the decolorizing rate can reach about 97%.Therefore,Ce^4＋ is an effective,economical,safe,nontoxic,environmental benign water treatment reagent. Besides,the investigation shows that the velocity of decolorizing can be greatly enhanced by ultraviolet radiation.
