摘要：

Four phenothiazines, promethazine, dioxypromethazine, chlorpromazine, and trifluoperazine have been separated by capillary electrophoresis using N, N, -dimethylformamide (DMF) as separation medium with UV absorbance detection. High voltage and concentrated buffer were used with small current and low electroosmosis. Good resolution and high column efficiency were obtained. Separation selectivity in DMI; was different from that in water because of the different solvation interactions. The influence of buffer composition on separation selectivities and electroosmosis were also studied.
