Abstract   CT (Carbon tetrachloride) is a one of persistent organic pollutants(POPs) in the groundwater, if CT in the sweage and residued in soils entrance into the aquifer, it will theat the water-supply safety for human being. Understanding of adsorption ability of soils to CT and migration rules of CT in the formation, may provide the basis for risk assessment and remediation of groundwater pollutions. For researching the migration of CT in different formations, adsorption behaviors of CT in the formation were simulated through batch-shake-equilibrium experiment, and adsorption isotherms were fitted by using of experiment results. It suggested that adsorption capacity of the fine particle medium is larger according to the experiments. Furthermore, between two same lithologic formation mediums, the one with high organic matter content has stronger adsorption ability, it suggest that organic matter content is a important factor on the migration of CT in the formation.
