摘要: 建立了采用气相色谱检测包括毛豆、青梗菜、柚子、姜、木耳、笋、茶叶、猪肉、鱼肉及鸡肉等多种食品基体中茚虫威残留的方法。采用丙酮+正已烷混合溶剂提取试样中茚虫威残留,ENVI-CARB固相萃取小柱净化植物源性产品、Florisil PR固相萃取小柱净化动物源性产品。对于气相色谱分析,定量限(LOQ)为0.005mg/kg,在添加浓度0.005~0.04mg/kg时,回收率及相对标准偏差分别为74.9%~106.4%及1.9%~11.5%。

Abstract: A gas chromatography(GC) method was developed for determination of indoxacarb residue in various food matrixes including green soybean,Brassica campestris L. grapefruit,ginger,agaric,bamboo shoot,tea,pork,fish and chicken. The indoxacarb residues in the samples were extracted with the mixture of acetone and n-hexane(1:2,V/V),and then the extracts were purified with ENVI-CARB solid phase extraction(SPE) cartridges for plant foodstuffs and Floirsil SPE cartridges for animal foodstuffs. For GC analysis,the limit of quantification(LOQ) is 0.005 mg/kg,and the average recoveries and relative standard deviation(RSD) for the spiked samples in the range of 0.005 to 0.04 mg/kg are in the range of 74.9% to 106.4% and 1.9% to 11.5%,respectively.
