摘　　要：[目的]建立一套快速、简单、准确的有机磷残留量检测方法。[方法]用聚二甲基硅氧烷(PDMS)固相萃取膜吸附萃取甘蔗汁中甲拌磷和特丁硫磷,经二氯甲烷脱附后,FID/GC直接检测。[结果]用PDMS固相萃取-气相色谱法检测了甘蔗汁中添加甲拌磷和特丁硫磷的标准品混合液,甲拌磷和特丁硫磷得到有效的分离和确认。[结论]PDMS固相萃取-气相色谱法操作简单,能快速、准确地检测有机磷农药残留。[Objective] To establish a fast,simple and accurate detection method for organophosphate residues.[Method] Phorate and terbufos in sugarcane juice were absorbed by the membrane extraction of PDMS solid phase extraction,then disported by dichloromethane and detected directly by FID/GC.[Result] Mixed liquid of sugar cane juice and phorate,terbufos standard substances were detected,and phorate and terbufos were effectively separated and recognized by PDMS-SPE-GC method.[Conclusion] PDMS-SPEM-GC is a simple,fast and accurate method to be detected of organ phosphorus pesticide residues.
