Magnesium(II) and calcium(II) are separated from each other and from several other metal ions by ion-exchange chromatography on a sulfonated macroporous resin of 1.8 to 2.0 mequiv/g capacity. The eluent is 1 M ammonium chloride or 0.03 M ethylenediammonium chloride. The separated metal ions are detected automatically with a color-forming reagent and are quantitated with the aid of a calibration plot.
