摘要： 以草鱼(Ctenopharyngodon idellus)、南美白对虾(Penaens vannamei)为实验材料,建立了水产品中呋喃丹残留量的气相色谱测定方法。样品经乙腈提取,正己烷去脂肪,Al2O3柱净化后进样分析。本方法线性范围为0.1～10.0 mg/L,相关系数r ≥0.9995;当呋喃丹的加标水平在0.02～1.0 mg/kg时,其回收率为78%～90%,相对标准偏差为2.49%～9.59%；方法的检出限为0.02 mg/kg。

Abstract: A capillary gas chromatographic （GC） method was developed for the determination of carbofuran residue in aquatic products （Ctenopharyngodon idellus and Penaens vannamei）. The sample was extracted with acetonitrile, defatted by hexane, re-extracted by acetoacetate and cleaned up with a Al2O3 column, and then determined by GC. The standard curve was linear in the investigated range of 0.1-10.0 mg/L. The correlation coefficients were more than 0.9995, the recoveries were 78%-90% with the relative standard deviations of 2.49%-9.59%at the spiking levels of 0.02-10.0 mg/kg. The detection limit of carbofuran was 0.02 mg/kg.
