In this experiment, the authors simplified the complexities and heterogeneities of the soil environment in order to study the impact of soil organic matters and minerals on the TCE sorption behaviors in homogeneous soils. The given minerals, which were mixed kaolin clay and silica sand according to the proportion of 3∶7 and served as the soil matrix structure, were added to different amounts of humic substance(f_oc=0.16%～2.29%)to comprise the model soils. The parallel experiments of the TCE sorption were carried out both in minerals and model soils respectively by using the batch experimental method. It is concluded that the sorption of the TCE was characterized by nonlinear isotherm. The linear sorption reaction was enhanced and the contribution rate of the minerals to the sorption was reduced with the increasing amount of the organic matters. The sorption contribution rate of minerals was less than 5% when the organic carbon content was more than 0.82%, and even could be neglected when the organic carbon content was higher than 1%. Also the original concentration of the TCE could affect the capacity of the sorption and the sorption contribution of the organic carbon and minerals in some way. The Freundlich sorption model was used to simulate the TCE isotherm sorption patterns in two segments, with C_e=500 μg/L as the boundary. The fitting exponential of Freundlich (n) decreased with the increasing TCE concentration. Besides, the contribution rate of the organic carbon increased while that of the minerals went down with the increasingly higher TCE concentration. When the TCE concentration varied from 50 to 500 μg/L and f_oc was 0.16%, the sorption contribution rate of minerals fluctuated in the range of 28%～16% and decreased to 3%～1% at f_oc equal to 1%, whereas the TCE concentration almost had nothing to do with their contributions.
