| 摘 要： | 目的 采用固相萃取（SPE）GC／MS分析技术，快速检验血中常见农药及杀鼠药。方法采用SPE-GC／MS法分析血中马拉硫磷、敌敌畏、甲基对硫磷、甲拌磷、灭多威、杀鼠迷、速灭威、久效磷、毒死蜱、灭害威等10种药物；比较OasisHLBcartridge、C18和C23种固相萃取柱同步提取的回收率及洗脱剂种类、洗脱剂和缓冲液用量对回收率的影响。结果固相萃取柱Oasis HLB cartridge提取率较高，在72．6％-112．0％之间；采用3mL氯仿做洗脱剂时回收率较好，在75．7％～127．2％之间；2mL磷酸盐为缓冲液最佳剂量。结论本文方法具有操作简便快捷，回收率高、重现性好、无杂质干扰等特点，可用于法庭毒物的检验。
