A new method for the chiral separation of epinephrine is presented based on the β-cyclodextrin (β-CD)-sodium dodecyl sulfate(SDS)-micellar electrokinetic chromatography(MEKC) separation of the analytes combined with electrochemical detection using gold microelectrode at +0.65 V(vs. SCE). The effects of detection potential, concentration of β-cyclodextrin, concentration of sodium dodecyl sulfate, pH value of electrolyte and loading voltage were discussed. An attempt was made to elucidate the plausible mechanism of the chrial recognition.
