摘　　要：采用MnO_2协助微波法对氯丹污染土壤进行实验研究,研究不同土壤质量、MnO_2投加量、氯丹浓度、土壤粒径对土壤中氯丹去除率的影响,确定最佳反应参数。实验表明:MnO_2协助微波法对土壤中的氯丹具有良好的去除效果,去除率可达到98.9%,最佳反应条件为:土壤质量为120 g,MnO_2投加质量比为5%,氯丹浓度为250 mg/kg,土壤粒径为1.18～2.8 mm。Chlordane contaminated soil was treated by microwave/MnO2, the effects of soil quality, MnO2 dosage, concentration of chlorine, soil particle size on removal rate of chlordane in soil were investigated, and optimum reaction parameters were obtained. Experiments showed that it had good removal effect on chlordane in soil by microwave/MnO2, and removal rate of chlordane was up to 98.9 %, the optimum reaction parameters were as followed: soil quality was 120 g,MnO2 was 5 %, chlordane concentration was 250 mg/kg, soil particle size was 1.18~2.8 mm.
