Sorption properties of talc for Hg (II) in water were studied. Effects of talc dosage, reaction time and pH on the adsorption were investigated, the adsorption isotherm was drawn, and the adsorption mechanism was analyzed. The results show that, the talc has good adsorption effect for Hg (II) in water,the adsorption results are in accord with Langmuir and Freundlich isothermal adsorption models, the adsorption mechanism mainly is surface adsorption, the complexation reaction also plays a certain role.
