Macroreticular chelating resins containing aminomethylphosphonic acid groups were prepared by reaction of methyl methacrylate/divinylbenzene copolymer beads with triethylenetetramine, followed by the reaction of the products with phosphorous acid and formaline. The adsorption capacities of this resin for Cu 2+ , Pb 2+ , Zn 2+ , Ni 2+ , Co 2+ , Ca 2+ , and Mg 2+ were determined at various pH values. The order of chelate stability for the resin was Cu 2+ > Pb 2+ > Zn 2+ > Ni 2+ > Co 2+ > Ca 2+ > Mg 2+ . Copper, nickel, zinc, calcium, and magnesium ions can be eluted with 1 mol dm −3 hydrochloric acid. The proposed resin appears to be useful for the removal of Ca 2+ and Mg 2+ from salt solution.
