ABSTRACT:

The preferential complexing tendency of different metal ions towards chelating agents anchored on a polymer has been used for separation of transition metals. The anthranilic acid group was anchored on the polymeric divinyl benzene styrene backbone in dioxane medium, at pH -7 and 9-10 respectively. This polymer bound chelating agent was used to separate copper(II), nickel(II) and cobalt(II) in the concentration range 1.0-01 mol/L. The separation of mixture of three components was quantitative using column chromatography.
