摘要：

A reversed electroosmotic flow (EOF) capillary electrophoretic method for the separation of eight aromatic acids was developed. A carrier composed of aqueous buffer solution (10 mM lauryltrimethylammonium chloride, 8 mM sodium berate and 2 mM sodium dihydrogenphosphate)-acetonitrile (7:3) was found to be the most suitable electrolyte for this separation. The analysis time (5 min) was shorter than that of standard capillary zone electrophoresis (21 min). The effects of pH, EOF modifier concentration and organic modifier (acetonitrile) concentration of the carrier on the migration behaviour of the solutes were also studied.
