| Abstract: | The effects of ionic liquids on micellar microstructures and separation performance in micellar electrokinetic chromatography(MEKC) were investigated.The experimental results showed that the addition of ionic liquids into micellar system would result in a decreased micellar surface charge density,an enlarged size of micelle and a slight enhancement of the polarity in the inner core of micelle.Prednisone,hydrocortisone and prednisolone were analyzed with MEKC to evaluate the separation performance.Hydrocorti... |
