摘要：

Single-column ion chromatography was used with ethylenediammonium tartrate in the eluent for the rapid separation of divalent metal ions and for the measurement of the complexation constants of divalent metal ions with tartrate. A theoretical framework was developed for the interpretation of the effect of pH, tartaric acid and ethylenediamine concentrations on the retention factors. Equilibrium constants for the ion-exchange process were evaluated and the concomitant enthalpy and entropy changes calculated.
