The chelation behavior of poly(2-hydroxy-4-acryloyloxybenzophenone) [poly(2H4ABP) or polymer I] obtained through the free-radical polymerization of 2-hydroxy-4-acryloyloxybenzophenone monomer and for crosslinked polymers prepared from the monomer and known amounts of the crosslinker divinylbenzene (DVB) [4 mol % of DVB for polymer II; 8 mol % of DVB for polymer III; and 16 mol 16% of DVB for polymer IV] toward the divalent metal ions Cu2+; Ni2+; Zn2+; and Pb2+ in aqueous solution was studied by a batch equilibration technique as a function of contact time and pH. The effect of the crosslinker; DVB; was also studied. The metal-ion uptake of the polymers was determined with atomic absorption spectroscopy; and the highest uptake was achieved at pH 7.0 for polymers I; II; III; and IV. The selectivity and binding capacity of the resins toward the investigated divalent metal ions are discussed. © 2008 Wiley Periodicals; Inc;
