An ion chromatographic method for the separation and determination of thorium in uranium mineralizations has been developed using a mixed ion-exchange column; IonPac CS5A containing both cation and anion exchange sites.Selective separation of U(VI) and Th(IV) was performed by online gradient elution using two mobile phases of composition 0.1 M (NH 4 ) 2 SO 4 / 0.1M HCl and 0.2 M (NH 4 ) 2 SO 4 / 0...
