摘要：

A method is described for determining the dissociation potentials of metal complexes using computerized flow‐injection potentiometric stripping analysis (CFIPSA). The dissociation potentials of Bi:NTA and Bi:EDTA complexes are determined at pH 2 by measuring the bismuth(III) concentrations (i.e., the counts in solutions containing the 1:1 complexes at different deposition potentials between −0.15 and −0.90 V vs. Ag/AgCl). Dissociation potentials of −0.35 and −0.50 V vs. Ag/AgCl have been found for Bi:NTA and Bi:EDTA, respectively. Copyright © 1990 VCH Publishers, Inc.
