摘　　要：土壤中有机质与无机矿物长期共存,其存在形式发生着变化。本文利用批实验的方法对三氯乙烯的吸附行为进行模拟研究,结果表明,土壤中有机质与无机矿物是以有机质-矿质复合体形式存在的,有机质与无机矿物的相互作用影响复合体的吸附性能,与有机质、无机矿物单体相比,复合体Kd、Koc明显发生变化;并提出了有机质-矿质复合体模型。After long period of interaction,the form of organic and inorganic minerals would change.Batch technique was used to make a comparative study of the sorption for trichloroethylene（TCE）.The results showed that the organic and inorganic minerals were existent in the form of organo-mineral complexes.The Kd and KOC of organic-mineral complexes changed more obviously than organic matters and inorganic minerals.The interaction between humic acid and simulated minerals affected the sorption of trichloroethylene.Based on an analysis of the conformation of the humic acid in the complexes,the authors formulated a model of organo-mineral to explain the results.
