摘　　要：研究并建立丁烯氟虫腈在大米中残留分析方法。样品以乙腈为提取剂,氨基固相萃取柱净化,甲醇和二氯甲烷(v/v,1/99)洗脱,供气相色谱测定。对大米样品进行添加回收率实验,分别添加0.10mg/kg、0.50mg/kg、2.0mg/kg,回收率在71.9%～98.2%之间,变异系数为2.78%-10.6%。方法的准确性、灵敏度均达到农药残留分析的要求。Gas chromatography was used to analyze the residue of butene-fipronil in rice. Residues of butene-fipronil were extracted from rice with aee/onitrile, and removed through an aminopmpyl Bond Elut （NH2） SPE column to purify the sample. The methanol and dichloromethane ane（v/v, 1/99） eluted it, and determined with GC equipped by ECD. The average recove,ies and coefficient of variations of the method were 71.9% - 98.2%, 2.78% - 10.6%, respectively. These restths showed that the methodwas in accord with demands of residue analysis of pesticide.
