Abstract

The biligand systems, Ln(III)-Aminopolycarboxylic acid1-Aminopolycarboxylic acid2 — have been studied pH-metrically and the analysis of the titration curves has shown the formation of 1 : 1 : 1 mixed ligand complexes. Their formation constants have been calculated at 30±1°C and the value of log K follows the order La(III)<Pr(III)<Nd(III).
