| In this paper, anion-exchange and CL-P204 extraction chromatography by which Co can be separated from Cd, Cu,Mn, Zn, Fe is investigated. Most Cd in the solution containing Co is separated by strong basic anion-exchange column after the solution is specially treated. Then, when the CL-P204 levextrel resin transformed by 0.5 mol/L NaAc(PH 4.0) isused as stationary phase and C1CHOOH-C1HOONNa(0. 1 mol/L) at pH 2. 5 as mobile phase,Co can be separated effectively from the other metal ions. This method is effective to separate Co from Cd, Cu, Mn, Zn, Fe and the condition of separation is simple and covenient. |
