A new chelating resin (PVESO‐AP) containing sulfoxide and 3‐aminopyridine (AP) was synthesized by using chloromethylated polystyrene‐ co ‐divinylbenzene (PS‐Cl) as material. Its structure was characterized by infrared spectra and elemental analysis. The adsorption capacities of the newly formed resin for Hg 2+ , Ag + , Cu 2+ , Zn 2+ , Cd 2+ , and Ni 2+ were determined at pH 2 and 5. In addition, the adsorption selective coefficients for Hg 2+ in several binary mixture systems were investigated by batch experiment method. The results showed that this resin had high adsorption selectivity for Hg 2+ . The adsorption kinetics and isothermal of PVESO‐AP for Hg 2+ at different temperatures were also investigated. The adsorption kinetics showed that the apparent activation energy E a was 13.71 kJ/mol. The results also showed that the Langmuir model was better than the Frundlich model to describe the isothermal process of PVESO‐AP resin for Hg 2+ . © 2008 Wiley Periodicals, Inc.
