A Thermodynamic Study of Complex Formation of La(III) and Ce(III) with Glutamic Acid.

Department of Chemistry, Bipin Bihari College, Jhansi 284 001 Manuscript received 2 January 1976; revised 18 May 1976 ; accepted 15 July 1976 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
