Abstract A new micelle capillary electrophoresis based on cyclodextrin micellar electrokinetic chromatography (MEKC) for the determination of bisphenol A and 10 alkylphenols in rat serum is reported. Several surfactants and dextrins were studied. Bisphenol A and alkylphenols were separated using a 50 microm x 50 cm capillary with 20 mM borate phosphate buffer (pH 8.0) containing 20 mM sodium dodecylsulfate and 5 mM gamma-cyclodextrin as carrier. The method could determine 0.6-2000 microg/mL of phenols in 100 microL serum by photometric detection at 214 nm. Using 2.0 mL serum, 1.0 ng/mL of phenols could be determined. The relative standards deviations were 6.3-7.7\% at 10 microg/mL in serum. The recoveries were 91.8-93.0\% with 10 microg/mL serum samples. Copyright 2001 John Wiley & Sons, Ltd.
