Influence of additives of metal ions to the back ground electrolyte on electrophoretic separation of aromatic hydroxy- and aminoacides
Keywords:
capillary zone electrophoresis, aromatic hydroxy- and aminoacides, complexes with metal ions.
Abstract
The influence of addition of metal ions (Cu2+, Co2+, Al3+, Fe3+) to the back ground electrolyte on
the increase of selectivity separation of aromatic hydroxy- and aminoacides due to complexation
processes was investigated by the method capillary zone electrophoresis (CZE).
Schemes of electrophoretic analysis of real objects with the use of Cu2+ ions in the composition
of back ground electrolyte were suggested.
