Thin Layer Ionophoresis of D-Block Metal Ions in Aqueous Solutions of Complex Forming Acids and Their Sodium Salts: Specific Separation of Pd2+and Pt4+from Numerous Metal Ions

摘要

Thin layer ionophoresis of d-block metal ions was studied at 100 volts for 3 h. Aqueous solutions of citric, tartaric and oxalic acids and their sodium salts were chosen as background electrolyte. The mechanism of migration is explained in terms of precipitation and adsorption. There is no significant heating during ionophoresis. Pd2+and Pt4+were separated from numerous metal ions.
