Potentiometric Studies on Some Binary and Mixed Ligand Complexes of UO2 (VI) [Part-III]

Abstract

Stability constants of binary complexes of UO₂(VI) with nitrilotriacetic

acid (NTA), lactic acid (LA) and protocatechuic acid (PCA) as ligands and

of mixed ligand complexes of UO₂(VI) with NTA as a primary ligand and

LA and PCA as secondary ligands at 20, 35, 50° and in different ratios of

water to non-aqueous solvents and at different ionic strengths have been

determined. The effect of dielectric constant and ionic strength on the

values of stability constants have been discussed on the basis of sterie

factors and structural characteristics of complex formed.
