A copolymer (4‐HAOF) prepared by condensation of 4‐hydroxyacetophenone and oxamide with formaldehyde in the presence of an acid catalyst proved to be a selective chelating ion‐exchange copolymer for certain metals. Chelating ion‐exchange properties of this copolymer were studied for Fe 3+ , Cu 2+ , Ni 2+ , Co 2+ , Zn 2+ , Cd 2+ , Pb 2+ , and Hg 2+ ions. A batch equilibrium method was employed in the study of the selectivity of metal‐ion uptake involving the measurements of the distribution of a given metal ion between the copolymer sample and a solution containing the metal ion. The study was carried out over a wide pH range and in media of various ionic strengths. The copolymer showed a higher selectivity for Fe 3+ ions than for Co 2+ , Zn 2+ , Cd 2+ , Pb 2+ , Cu 2+ , Ni 2+ , and Hg 2+ ions. © 2003 Wiley Periodicals, Inc. J Appl Polym Sci 89: 787–790, 2003
