摘　　要：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 ofThe stability constants and thermodynamic functions for complexes of lanthanum with some amino acids have been determined by temperarature titration calorimeter at 298.15 K.
