Several of new chelating resins containing sulfoxide and heterocyclic functional groups (3-aminopyridine and 2-mercaptobenzothiazole) based on macroporous chloromethylated polystyrene were synthesized and characterized by elemental analysis and infrared spectra. Their adsorption capacities towards Zn2+, Cu2+, Pb2+, Hg2+ and Ag+ at pH 3.0 and 6.0 were investigated in detail. It was found that the adsorption capacities of the resins containing bis[(3-pyridylaminoethyl)sulfoxide or (2-benzothiazolylthioethyl) sulfoxide for the above ions were higher than that on ones containing single above-mentioned groups.
