Micellar Electrokinetic Capillary Chromatography

Micellar Electrokinetic Capillary Chromatography (MEKC) was employed to the analysis of aniline, phenol and 2,5-dinitrophenol using an end-column amperometric detector with a carbon cloth electrode. The current condition of separation is a solution of 25 mM Na2HPO4, 25 mM Na2B4O7, and 50 mM SDS (pH 9.11); applied voltage, 10 kV; hydrodynamic injection for 15 s at 15 cm; applied potential for electrochemical detection, 500 mV. Absorbance electropherograms is also recorded for comparison.
