Abstract

Abstract

Natural and surfactant-modified geomaterials(such as zeolite, bentonite, dacite and rhyolite) were used to remove chlorohydrocarbons from wastewater in this paper.The results show that surfactant(HDTMA-Br)can enhance the removal of chlorohydrocarbons by geomaterials, of which the modified bentonite shows the highest degree of removal of dichloromethane, trichloromethane, tetrachloromethane, trichloroethylene, tetrachloroethylene, and chlorobenzene at 9.1, 18.9, 43.0, 20.0, 32.4 and 30.3μg·g^-1, respectively.A good linear correlation exists between removal of chlorohydrocarbons and K_oc(which refers to the distribution coefficients of organic substances between the organic carbon of sediment and water).
