[Determination of carbofuran residue in aquatic products by gas chromatography].
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.
