In Continuation of our previous work, stability constants of complexes of Pr(III), Sm(III) and Gd(III) with glutamic acid as lignad have been determined. The stability constant has been determined by the study of proton ligand stability constants.
The stability constant of metal chelates has been determined potentiometrically by Bjerrum method1 involving Irving – Rossotti pH metric titration technique2-5 at constant ionic strength of (0.01M) KNO3 and at constant temperature 20±10 C in water dioxane (60:40) medium.The stability constant of metal complexes with Glutamic acid shows the sequence …… Sm(III) > Gd(III) > Pr(III).
