Selective extraction of Hf(IV) over Zr(IV) from aqueous H sub(2)SO sub(4) solutions by solvent extraction with acidic organophosphorous based extractants

BACKGROUND The present paper describes the selective extraction of Hf(IV) over Zr(IV) using two acidic extractants (D2EHPA and Cyanex 272) and its mixture with LIX 63 from sulphate medium. To achieve this, extractant and H sub(2)SO sub(4) concentrations were varied and results obtained. RESULTS Sele...
