The thermodynamic functions of La(III) and Ce(III) with glutamic acid were determined potentiometrically in aqueous solution at 30°±0.1° and 40°±0.1° in an ionic strength of 0.1 M KCI. The stability constants (log k) changes in free energy (∆G), enthalpy (∆H) and entropy (∆S) for complexes are reported.
