ION EXCHANGE SEPARATION OF METAL IONS

· Analytica Chimica Acta (Netherlands)
An ion exchange method that depends on the selective complexation of metal ions by EDTA (ethylensdianuinetetraacetic acid) is discusscd Selectivity is achieved by proper choice and control of pH. The uncomplexed metal ions are retained by a short cation exchange column, while the complex metals pass quantitatively through the column Quantitative ion exchange separations are attained quickly because a short (4-cm) column is used. Excellent pH control is effected by incorporating a buffer in the sample to the separated and by treating the resin colunm with the same buffer solution. The ion exchange retention of several metal cations in EDTA solution was studied as a function of pH. From the behavior of individuai ions, predictions can be made as to the mixtures that can be separated by this method. Several actual separations are reported. (J.H.M.)
