The simultaneous separation of chlorinated phenols including structural isomers by capillary electrophoresis was studied. Structural isomers of mono- and dichlorophenols and phenol were selected as analytes because of their low hydrophobicity. In order to detect them using mass spectrometry in the future, three volatile running solution (ammonium acetate, ammonium hydrogencarbonate and ammonium carbonate) were investigated. The migration behavior of analytes was found to be governed by their dissosiation constants. When an ammonium hydrogencarbonate solution (pH 8.1) was used, the peak shapes were the best, and all dichlorophenol isomers completely separated. The optimized concentration of the solution was 20 mM. All analytes were completely separated within 8 minutes.
