Acrylamide in papcr was cxtractcd with ultrapurc water atωt • lhc aqucous cxtract was centrifuged and filtrated with 0.45μm filtcr membrane. and then concentrated by Nilrogen eva阳rators. ηle concenlrated liquid was p町证ìed by solid-phasc cxtraction (SPE ) and detcrmined by HPLC. The limit of detection (LOD) of thc dcvcloped method was 1 0μglkg. 切lis mcthod has thc advantages of convenient operalion. high sensilivily . excellent accuracy and good rcproducibility and is 由e
