A simple and rapid method for the isolation of seven synthetic pyrethroid insecticides (methothrin, fenpropathrin, cyhalothrin, permethrin, cypermethrin, fenvalerate, deltamethrin) with a solid phase extraction (SPE), utilizing Sep-Pak C18 cartridges, from human urine and plasma is presented. The detection of the insecticides was performed using a wide bore capillary gas chromatograph (GC) with flame ionization detection (FID). The insecticide-containing samples mixed with 70% methanol were directly applied to the cartridges and eluted with 2 ml chloroform. The recoveries using the cartridges were between 90-102% for urine and 81-93% for plasma. Mixing samples with 70% methanol prior to extraction, seems very useful for the screening of synthetic pyrethroid insecticides.
本文介绍了一种利用Sep - Pak C18柱进行固相萃取（SPE），从人尿液和血浆中分离七种合成拟除虫菊酯类杀虫剂（烯丙菊酯、甲氰菊酯、氯氟氰菊酯、氯菊酯、氯氰菊酯、氰戊菊酯、溴氰菊酯）的简单快速方法。使用配备火焰离子化检测器（FID）的宽口径毛细管气相色谱仪（GC）对杀虫剂进行检测。将含有杀虫剂的样品与70%甲醇混合后直接加到柱上，并用2 ml氯仿洗脱。柱的回收率尿液为90 - 102%，血浆为81 - 93%。萃取前将样品与70%甲醇混合，对合成拟除虫菊酯类杀虫剂的筛查似乎非常有用。
