Özet

The suitability of capillary zone electrophoresis for the determination of stability constants of metal complexes was investigated. Three variants were tested viz., the frontal analysis, the Hummel-Dreyer method and the vacancy peak method, in the step-wise complexation between copper(II) and 1,10-phenanthroline as well as 2,2'-bipyridyl. The investigation reveals that CZE has attractive features for the quantitative study of complex formation with neutral ligands. However, the full exploitation requires more sensitive detection systems and application of an automated CZE system.
