The metal ion‐binding properties of poly(sodium 4‐styrenesulfonate) in conjunction with membrane filtration were investigated for Cu(II), Cd(II), Co(II), Cr(III), Hg(II), Ni(II), Pb(II), Zn(II), and Fe(II). Different experiments were carried out at different pH's, metal ion concentrations, polymer concentrations, and molecular weight fractions. Only Fe(II) and Cr(III) were retained at pH 1, which allows a selective separation of these metals from all the other metal ions. At pH 3 the retention ability of this polymer increased for all the metal ions. On the other hand, the metal ion‐retention properties are dependent on the polymer/metal ratio. © 1998 John Wiley & Sons, Inc. J. Appl. Polym. Sci. 70: 219–225, 1998
