Popis:	Ion exchange resins selective for the sequestration of Fe3+ from aqueous solutions containing citrate were prepared by the molecular imprinting technique. Sorption characteristics of imprinted resins prepared with high (85 mole%) and low (3 mole%) amounts of covalent cross‐linking were examined. Experiments to determine loading capacity and selectivity, relative to several metal ions of physiological significance, were performed. The Fe3+ capacity of the highly cross‐linked resin was larger but the selectivity was lower.
