Separation of Aniline Derivatives by Micellar Electrokinetic Capillary Chromatography

摘要

A micellar electrokinetic capillary chromatography (MECC) was developed for the determination of aniline and 6 substituted anilines.The seven components were separated within 25 min in the buffer solution of 40 mmol/L sodium borate and 100 mmol/L SDS.It was found that the separation was dependent on operating voltage, pH value, borate and SDS concentrations.The analytical performance was examined in terms of linear response and reproducibility.Wastewater was determined by the established method.
