Summary
A water-insoluble poly (β-diketone) chelating resin has been prepared by the controlled oxidation of poly(vinyl alcohol) with chromic acid. The polymer forms stable complexes with divalent and trivalent cations, such as Co+2, Cu+2, Mn+2, Ni+2, Fe+3, Au+3, and UO2 +2, and removes them completely from dilute aqueous solution. The ions may be recovered quantitatively from the resin complex by elution with dilute aqueous acid and the resin is reusable
