建立气相色谱法检测莴笋中几种有机氯、菊酯类农药残留的分析方法。样品采用乙腈提取,Canbon-NH2柱净化,DM-1色谱柱分析。莴笋中几种农药在0.04 mg/kg、0.40 mg/kg两个添加水平下加标回收率在92.6%~118%范围,RSD(n=3)均小于10,方法理论最小检出限均可达0.004 mg/kg。该方法满足莴笋中这几种农药残留的检测要求。
建立氣相色譜法檢測萵筍中幾種有機氯、菊酯類農藥殘留的分析方法。樣品採用乙腈提取,Canbon-NH2柱淨化,DM-1色譜柱分析。萵筍中幾種農藥在0.04 mg/kg、0.40 mg/kg兩箇添加水平下加標迴收率在92.6%~118%範圍,RSD(n=3)均小于10,方法理論最小檢齣限均可達0.004 mg/kg。該方法滿足萵筍中這幾種農藥殘留的檢測要求。

A method was established for the determination of some kinds of organochlorine and pyrethroid in lettuce by GC-ECD. Residues of the pesticides were extracted by acetonitrile, cleaned up with Canbon-NH2, analyzed with DM-1 chromatographic column. The average recoveries of the pesticides were between 92.6%~118%at two concentration of 0.04 mg/kg and 0.40 mg/kg, and the values of RSD(n=3) were below 10. The theoretical minimum detection limit was 0.004 mg/kg. The method was effective for determining the residues of some pesticides in lettuce.
