Abstract
The multiparametric refinement program MUCOMP fits the overall stability constants of complexes M qH jA p (M: metal ion, H: proton, A: ligand) and permits simultaneously the detection of the minor species and the compensation of systematic errors (total concentrations of ligands, cation, impurities and electrode cell characteristics). The processed data (reagent volume, potential) are collected from base titrations of complexant—cation mixtures. It is the last element of a chain of original programs intended for the study of complex formation by potentiometry. It was tested on the copper complexes of N, N-dimethylaminomethylphosphonic acid. The method will be extended, in the future, to allow analysis of mixtures of cations or protolytes.
