中文摘要	the adsorption behavior of exogenous thorium on soil was studied to evaluate the contaminated risk on soil. the adsorption capacity, equilibrium time, distribution coefficient and desorption ability were investigated by the experiments of static adsorption. the strong adsorption ability of exogenous thorium on soil samples was observed by high adsorption ratio (> 92%) and low desorption ratio (< 5%) in equilibrium, and the biggest distribution coefficient was over 10(4). the adsorption capacity and equilibrium time were related to soil properties. according to the results of adsorption, freundlich equation (r >= 0.916 7) and elovich equation (r-2 >= 0. 898 0) were primely fit for describing the thermodynamics and kinetics of the adsorption of exogenous thorium on soil samples, respectively, which indicated that the adsorption was belonged to the nonlinear adsorption, and was affected by the diffusion of thorium on soil surface and in mineral interbed. sequential extraction procedure was employed to evaluate the bound fractions of exogenous thorium adsorbed on soil samples.
