A　simple　and　rapid　pressurized　isocratic　capillary　electrochromatography　(pCEC)　method　has　been　developed　to　separate　six　pyrethroid　pesticides.　The　effects　of　pH　of　buffer,　organic　solvent　content,　buffer　concentrations　and　applied　voltage　on　the　separation　of　six　pyrethroids　were　investigated.　Under　the　optimized　conditions,　the　pCEC　method　developed　allows　baseline　separation　of　a　complex　mixture　of　six　pyrethroids　in
