The cation-exchange resin Amberlite IR-120 has been modified by adsorption of neutral red at pH 3.0. Several binary and ternary separations of important metal ions were achieved on the basis of their Kd values when chromatographed with different mobile phases. To demonstrate its practi-cal utility Zn2+ and Zr4+ were selectively separated from a synthetic mix-tures of metal ions on a column of the material. Zn2+ and Ca2+ ions were quantitatively separated and determined in the pharmaceutical preparation Zevit.
