The evaluation for adsorption ability of landfill cover soil is significantly important to pollution control of volatile chlorinated hydrocarbons (VCHs). Adsorption characteristics of 8VCHs in landfill cover soil, such as dichloromethane (DCM), trichloromethane (TCM), 1,1,2-trichloroethane (1,1,2-TCA), carbon tetrachloride (CT), cis-1,2-dichloroethylene (c-1,2-DCE), trichloroethylene (TCE), tetrachloroethylene (PCE) and chlorobenzene (CB), was completely investigated by static adsorption experiments in this work, respectively. The results demonstrated that adsorption isotherm of chlorinated alkanes and chlorinated aromatic hydrocarbons in the landfill cover soil were both consistent with the Freundlich model (R²=0.81~0.87), and the adsorption isotherm of chloroalkene in the soil was consistent with the Langmuir model (R²=0.87~0.96). The adsorbing capacity of VCHs in cover soil predicted via fitting results were showed as follows. The adsorption rate of VCHs was increased with the increasing number of chlorine substitution; the absorption capacity of chlorinated alkanes was greater than chloroalkene and chlorinated aromatic hydrocarbons in the same number of chlorine substitution. Consequently, the prior pollution control of chlorinated alkanes with higher concentration should be considered in the landfill operation management. Moreover, in this study, the 8VCHs adsorption equilibrium time were all about 20h, but the result of adsorption rate in the range of 26~250μg/(g_soil·h) was much higher than those reported by references. The bioaugmentation soil potential could effectively reduce the adverse effect of VCHs on the environment.
