Abstract

The capillary electrophoretic separation of substituted phenols was examined using high-molecular-mass polyethyleneimine (PEI) as a buffer additive. The added PEI to the running buffer showed a strong interaction with the phenols and affected the electrophoretic mobilities and migration order of phenols. The influence of pH, organic solvent and concentration of polyelectrolyte on the electrophoretic mobilities of analytes was investigated.
