摘　　要：以125W高压汞灯为光源,研究了在模拟太阳光(λ>300nm)作用下,冰相和水相中Fenton试剂对对氯苯酚(4—CP)光转化的影响。结果表明,冰相和水相中均存在Fenton效应,并且4—CP的转化率均随着H2O2和Fe2+初始浓度的增加而增加,随4—CP初始浓度的增加而降低。这表明冰相和水相中Fenton反应的作用和机理相似,但冰相体系中4—CP的转化率明显低于水相。The effect of Fenton reagent for photoconversion of para-chlorophenol （4—CP） both in ice and in water under simulated sunlight irradiation（λ300 nm） had been researched.The results show that Fenton reaction occurred both in ice and in water,and the conversion rate of 4—CP increased with the initial concentration of H2O2 and Fe2＋,but decrease with that of 4—CP.The results indicated that Fenton reaction has similar effect and mechanism both in ice and in water,but the conversion rate of 4—CP in ice is significantly lower than that in water.
