Rare Earth Metal Complexes of N-Phosphonomethyl Glycin

Abstract

Stability constants of binary complexes of the type M–A, where M = Pr(III), Nd(III), Gd(III) and A = N-phosphonomethyl glycine have been determined in aqueous medium at 303K and 0.10 M (KNO₃) ionic strength by using Irving-Rossotti pH titration technique.
