Abstract

The composition and stability constants of La (III), Nd (III), Gd (III), UO2 (II) and Th (IV) complexes with hydroxamic acid derivatives have been determined by conductometric and potentiometric measurments. The proton reagent stability constants and stepwise- formation constants were measured and the free energy changes were calculated for the ligands and their chelates. The chemical structure of the chelates were determined on the basis of conductometric measurments, elemental and thermal analyses.
