Abstract  

The extraction of actinium with HDEHP from Cl and NO 3 systems has been investigated. It was found that extraction of actinium from HCl solutions is much better than from HNO3 solutions. Stability constants of the actinium complexes Ac(X)2+, X=Cl or NO 3 , were determined. Our results show that actinium formed less stable complexes with Cl than with NO 3 ligands.
