[目的]比较碱性条件下3种吸波介质对微波法降解土壤中氯丹的影响。[方法]以农药生产企业搬迁遗留场地土壤为研究对象，研究了在含水率为20%、碱性条件下 Cu2O、MnO2、粉末活性炭3种吸波介质对土壤升温及氯丹去除率的影响；同时以活性炭为最佳吸波介质，研究了其添加前后对土壤中氯丹去除率的影响，并考察了增大土壤处理量对氯丹去除率的影响。[结果] Cu2O、MnO2、粉末活性炭3种吸波介质对氯丹去除率的影响大小排序为：粉末活性炭＞MnO2＞Cu2O。相同微波条件下，氯丹去除率随土样质量增加而降低，但微波利用效率随土样质量增加而不断提高并趋于平衡。[结论]为进一步的工程应用提供了理论依据。

Objective] This study almed to compare the effects of three absorbing medium on microwave degradation of chIordane in contaminated soiI under alkaline condition. [Method] SoiI sampIes were coI ected from the original site of a reIocated pesticide production enterprise as experimental materials, to investigate the effects of Cu2O, MnO2 and activated carbon powder as absorbing medium on soiI warming and removal rate of chIordane under alkaline condition with 20% moisture content. In addition, the effects of activated carbon as the optimal absorbing media on the removal rate of chIordane in contaminated soiI were analyzed, and the effects on the removal rate of chIordane in different weights of soiI sampIes were investigated. [Result] The effects of three different absorbing medium on the removal rates of chIordane demonstrated a descending order of activated carbon > MnO2 > CuO2. Under the same microwave condition, the removal rate of chIordane decreased with the increase of soiI weights, but the utiIization efficiency of microwave was improved continuousIy and tended to be stabiIized with the increase of soiI weights. [Conclu-sion] This study provided a theoretical basis for further Iarge-scale appIication in soiI remediation.
