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 0.999 5, 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.
建立了一种毛细管气相色谱（GC）法，用于测定水产品（草鱼和南美白对虾）中的克百威残留量。样品用乙腈提取，用己烷脱脂，再用乙酰乙酸重新提取，并用氧化铝柱净化，然后用气相色谱法测定。在所研究的0.1 - 10.0 mg/L范围内，标准曲线呈线性。相关系数大于0.999 5，在0.02 - 10.0 mg/kg的加标水平下，回收率为78% - 90%，相对标准偏差为2.49% - 9.59%。克百威的检出限为0.02 mg/kg。
