A novel water treatment agent, chloromethyl polystyrene resin supported task-specific ionic liquid(PS-CH2-(CH2)16Im) was synthesized by a bonding method. Cr(Ⅵ) and methyl orange (MO) were selected as model anionic pollutants. The performance of selective removal of anionic pollutants in water was systematically investigated by both static and dynamic column tests. The results showed that PS-CH2-(CH2)16Im had good selective adsorption for anionic pollutants. The adsorption equilibrium could be reached in 30 minutes, with static maximum adsorption capacity of 90.9 and 62.8 mg/g for Cr(Ⅵ) and MO, respectively, and also could effectively remove Cr(Ⅵ) at a concentration as low as 0.004 mg/L. PS-CH2-(CH2)16Im was easy to regenerate and recycle at least 5 times without obvious loss in adsorption performance. By measuring the association constant, it was known that the adsorption mechanism of PS-CH2-(CH2)16Im on anionic pollutants was ion association.
