Mixed ligand complexes of some lanthanides with N, hydrazinediacetic and malic acids

ABSTRACT

The formation constants of mixed ligand complexes of hydrazinediacetic [H[2]Z] and malic [H[2]L] acids have been determined potentiometrically in 0.1 M KN03 and 30 +/- 0.1°C. The stoichiometry of the formed complexes was evaluated by conductimetric method and found to be 111 [LnZL]
