The cation exchange chromatographic studies for the analysis of transition metals have been described. The quantitative separation of a mixture of Fe(Ⅲ), Cu(Ⅱ), Zn(Ⅱ), Ni(Ⅱ), Cd(Ⅱ), Co(Ⅱ) and Mn(Ⅱ) has been obtained by elution, through a 28cm column of the resin, Dowex 50 × 4 (100∼200 mesh), using 0.45 M NaNO3+ 0.05 M Na-tartrate solution as eluent, starting with the eluent of pH 3.5, followed stepwise by pH 4.0 and 4.5. A comparison between the calculated and the observed peak positions in the elution curve has been shown. The relative stability constants for tartrate complexes of some transition metals have been calculated by using distribution ratios obtained in this separation procedure.
