| 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,450 W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.Fe2＋（2.5 g/L）投加量为1.0 mL,H2O2（6%）投加量为1.0 mL,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40 m in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 Fe2+ solution is 1.0 mL with the concentration 2.5 g/L,and the volume added of H2O2 solution is 1.0 mL with the concentration 6%,and the reaction time is 40 min,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. |
