Summary A new chelating adsorbent, zinc silicate-bonded diethyldithiocarbamate (DTC) has been prepared for the separation and preconcentration of some transition metal ions. The distribution coefficients (Kd values) of 15 metal ions have been estimated in solution at various pH's and some quantitative separations have been achieved. The high selectivity for Pd(II) has been utilized for its preconcentration from dilute aqueous solutions; quantitative elution is effected with acidic 4% thiourea solution.
