Deltamethrin residue in apple and soil was extracted with acetonitrile, and was determined by gas chromatograph after cleaned up with florisil column. The results showed that the recovery of the method was 96.44%-111.82%,with RSD being 1.21%-4.55%, the linear range of working curve was 0.005-0.4 mg/kg,and the linear correlation was 0.999 8. The method had merits of simplicity, accuracy and rapidity.
