Abstract The cation exchange separation of metallic chlorides by hydrochloric acid on an Amberlite CG-120 resin (200-400 mesh) column was investigated. Commercially available resin was used in the experiments after the “fines” were removed by several water washings. A resin column (24 cm long by 12 mm diameter) gave excellent separation of sodium and potassium, with a total volume of 500 ml of 0.5N HCI at a flow rate of 0.55 ml/min. The recovery of each metal was 100%. Elution of the other three metals required 1100 ml of liV HCl; separation was very good but recoveries were poor. AH of the metals were determined with a Beckman DU with photomultiplier and hydrogen-oxygen flame attachment.
