Abstract: The separation of Co2+ from Zn2+, Cd2+ by anion-exchange chromatography was discussed. The chromatographic column containing anion resin 201×7 whichwas saturated with a solution of ammonium chloride. The effects of the eluant acidity and eluant composition on the separationwere investigated. The results indicate thatthis anion-exchange chromatography is suitable to the separation of Co2+ from Zn2+, Cd2+, and the condition of separation is simple and convenient. When the column is saturated with NH4Cl solution (2.0 mol/L, pH=4.0), the separation can be completed effectively. Zn2+ and Cd2+ can also be separated when different eluants are used and the pure solution with high concentration of Zn2+, Cd2+ respectively can be obtained easily.
