摘要：

Non-aqueous capillary electrophoresis was applied to the separation of phenol derivatives included in the US Environmental Protection Agency list of priority pollutants and European Union directive 76/464/EEC concerning dangerous substances discharged into the aquatic environment. Best results were obtained with 60 mM ammonium acetate solution in acetonitrile-0.1 M KOH methanolic solution-acetic acid (74:25:1) as running buffer. A significant sensitivity enhancement was observed when field-amplified sample stacking in non-aqueous media was assayed for the study of low concentrated samples. (C) 1999 Elsevier Science B.V.
