A　new　method,　pressurized　CEC　with　end-column　amperometric　detection　using　carbon　paste　electrode,　has　been　developed　for　the　separation　and　determination　of　five　phenolic　xenoestrogens　in　chicken　eggs　and　milk　powder　samples.　Efficient　separation　of　five　analytes　was　performed　by　pressurized　CEC　using　a　mobile　phase　consisting　of　60%　v/v　ACN　and　40%　v/v　Tris　buffer　(5　mmol/L,　pH　8.0),　+6　kV　of　applied　voltage　and　7.0　MPa　of　supplementary　pressure.　Detection　limits　of　50,　5,　2,　10　and　20　ng/mL　for　pentachlorophenol,　bisphenol-A,　2,4-dichlorophenol,　4-tert-octylphenol　and　4-nonylphenol,　respectively,　were　achieved　using　carbon　paste　electrode　as　working　electrode　and　+0.8　V　as　detection　potential.　Matrix　solid　phase　dispersion　extraction　method　had　been　employed　during　sample　preparation　procedure,　and　mean　recoveries　ranged　from　79.2　to　102.6%　at　different　concentrations　of　phenolic　xenoestrogens　for　spiked　egg　and　milk　powder　samples　were　obtained.　©　2010　WILEY-VCH　Verlag　GmbH　&　Co.　KGaA.
