Abstract: The stability constants and thermodynamic functions for complexes of lanthanum with some amino acids have been determined by temperarature titration calorimeter at 298.15 K. The enthalpy change makes a predominant contribution to the stability of these complexes. The ring in amino acid associated with lanthanum iron helps to enhance the stability of complexes
