Amberlite XAD‐2 has been functionalized by coupling through –SO2‐with ethylenediamine, propylenediamine, and diethylenetriamine to give the corresponding polyamine chelating resins I–III. The solid metallopolymer complexes of the synthesized chelating resins with Cu2+, Zn2+, Cd2+, and Pb2+ were synthesized. The polyamine derivatives and their metal complexes were characterized by elemental analysis, spectral (IR, UV/V, and ESR), and magnetic studies. The batch equilibrium method was utilized for using the chelating polyamines for the removal of Cu+2, Zn+2, Cd+2, and Pb+2 ions from aqueous solutions at different pH values and different shaking times at room temperature. The selective extraction of Cu+2 from a mixture of the four metal ions and the metal capacities of the chelating resins were evaluated using atomic absorption spectroscopy. © 2005 Wiley Periodicals, Inc.
