Abstract:
A novel method was developed for the determination of deltamethrin residues in exporting eel by GC. Samples were extracted by acetonitrile, purified by a column filled with Florisil, and analyzed with GC. At the linear range of 0.002~0.010 mg/kg, recoveries ranged from 79.2% to 85.9%, and the coefficients of variation were between 4.2% and 5.8%. The detection limit was 2.0 μg/kg (S/N=3). This method was simple, sensitive and precise, suitable for the qualitative and quantitative analysis of deltamethrin residues in exporting eel.
