%X A new anion-exchange chromatographic method was developed for the separation of cobalt from zinc, cadmium and copper. Experimental results showed that, in a 2 mol/L sodium chloride, 0.1 mol/L sodium sulphite and initial pH 4.5 solution, copper(II) was reduced to copper(I) and pH was decreased to 4.0. As the solution was driven through a 2017 anion-exchange chromatographic column, zinc, cadmium and copper were effectivelyseparated and the loss of cobalt was about 0.7%. This method is simple, rapid and effective, and has been successfully applied to the separation of cobalt in leach liquor of a zinc plant residue after sulphated calcination.
