摘要：
The formation constants of the ternary complexes of lanthanum, chosing bipyridyl, 1, 10-phenanthroline, maltol, kojic acid or acetylacetone as primary ligands and amino acids (glycine, beta-alanine or phenylalanine) as auxiliary ligands, have been determined potentiometrically in aqueous medium and 0.1 M KNO3 at 30 degrees C. The stability order of these ternary complexes is in the order : phenylalanine > beta-alanine > glycine. Influence of the ligand structure on the stability of the complexes has been discussed.
