Abstract

<jats:title>Abstract</jats:title> <jats:p>Several anions were found to penetrate into a strongly acidic cation-exchange resin by the aid of complexation with Fe3+ ion to give dimeric species, such as [(–S)2Fe(A)Fe(S–)2] (–S: benzenesulfonate bound to polymer network; A2−: HPO42−, HPO32−), and species having a composition of (–S):Fe:A = 2:1:1 (A−: OH−, H2PO2−).</jats:p>
