| 摘 要： | 采用光助Fenton氧化法处理间氨基苯酚模拟废水,考察了光强、Fenton试剂的用量、初始pH、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:在不同光源下(闭光、高压汞灯照射以及较强太阳光照射),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法催化氧化降解间氨基苯酚溶液的过程。选择1.5mL2.5g.L-1FeSO4.7H2O,1.0mL6%H2O2,初始pH=3.5,太阳光照射下降解间氨基苯酚效果较好,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: | m-Aminophenol in water was degraded by photo-Fenton technique.Effects of light intensity,reaction time,Fenton reagent dosage and initial pH on degradation of m-aminophenol were investigated.Kinetics for degradation of m-aminophenol was initially discussed,too.The results show that high pressure mercury lamp with 450 W and sunlight can accelerate degradation of m-aminophenol.When pH is 3.5,FeSO4·7H2O is 2.5g·L-1（1.5mL）,H2O2 is 6%（1.0mL）and reaction time is 40 min,degradation of m-aminophenol is over 99%,the kinetics for degradation of m-aminophenol by solar-Fenton conforms to first-order reaction equation. |
