微波辐射Fenton试剂氧化催化降解水中三氯乙烯

对微波辐射与Fenton试剂氧化催化法相结合降解水中三氯乙烯进行了研究。采用单因子法考察了反应时间、Fenton试剂用量和配比、反应物初始浓度、PH值，微波功率和压强等条件对脱氯率的影响。结果表明，三氯乙烯脱氯率随微波功率，压强、反应时间的增加而增加，随以应物初始浓度的增加而降低。Fenton试剂用量，比例和反应物初始Ph有一个最佳值。采用正交试验法对影响脱氯降解作用明显的催化剂量、Fenton试剂配比，反应时间，微波功率进行了优化分析，结果表明，在Fenton试剂摩尔比为60，Fenton试剂用量10%，反应时间12min、微波功率750W的最佳条件下，三氯乙烯脱氯率可以达到87.08%。

The Dechlorination of Trichloroethylene in Water by Fenton Reagent Oxidation under Microwave Radiation

The trichloroethylene in water was treated by Fenton reagent oxidation under microwave radiation. The effect of treating condition, including the treatment time, the weight and molar ratio of Fenton reagent, the initial concentration and pH of trichloroethylene, power of microwave radiation and pressure on the rate of dechlorination was studied by single factor method. It is obvious that the rate of dechlorination is related to treating conditions. The rate of dechlorination increases with the treatment time, power of microwave radiation and pressure, and decreases with the initial concentration of trichloroethylene. The weight and ratio of Fenton reagent and pH have the optimum conditions. In the optimum conditions : the molar ratio of Fenton reagent is 60, the weigh of Fenton reagent is 10%, the treatment time is 12 min, power of microwave radiation is 750W,the rate of dechlorination of trichloroethylene can reach up to 87.08%.
