| 摘 要： | 采用光助Fenton氧化法处理对氨基苯酚模拟废水，考察了光强、Fenton试剂的用量、初始pH值、反应时间对降解效果的影响，初步探讨了其降解动力学规律．结果表明，450W高压汞灯照射以及较强太阳光照射的条件均可以明显加快Fenton法催化氧化降解对氨基苯酚溶液的过程．Fe^2＋（2．5g／L）投加量为1．0mL，H2O2（6％）投加量为1．0mL，初始pH值为4，太阳光照射下降解对氨基苯酚时效果较好，反应40min后降解率高达99％；降解过程符合准一级反应动力学方程．

| Abstract: | p-aminophenol in water was degraded by photo-Fenton technique. Effects of light intensity reaction time, Fenton reagent dosage, initial pH value on degradation of p-aminophenol were investigated. Kinetics for degradation to p-aminophenol was initially discussed too. The results show that high pressure mercury lamp with 450 W and sunlight can accelerate degradation of p-aminophenol. When pH value is 4, the volume added of Fe^2＋ solution is 1.0 mL with the concentration 2.5 g/L, and the volume added of H202 solution is 1.0 mL with the concentration 6% , and the reaction time is 40 rain, the degradation rate of p-aminophenol is over 99% , the kinetics for degradation of p-aminophenol by photo-Fenton conforms with first-order reaction equation. |
