A bifunctional cation exchange resin (R4PS) having both phosphonate and sulfonate groups was derived from macroreticular poly (ω-bromobutylstyrene-co-divinylbenzene) . Phosphorus and sulfur contents of R4PS were 2.2 and 2.5 mmol/g, respectively, and its acid capacity was 6.6 meq/g. R4PS exhibits the characteristic metal ion selectivity, which is different from that of each monofunctional resin containing phosphonate or sulfonate group alone. In the strongly acidic region below pH 2, R4PS has higher capacities for uptake of Fe (III) than does a corresponding monofunctional phosphonate resin. In column-mode uptake of Fe (III) from strongly acidic feeds, R4PS exhibited excellent kinetic performances because of its high swelling in the wide pH range.
