| Abstract: | A method for the extraction, purification and GC determination of nine pyrethroid pesticides used in three kinds of vegetables was studied. The pesticide residues were extracted with acetonitrile, purified by a SFE Florisil-1 g column, and determined with GC-ECD gas chromatography. The method detection limit is 0. 0004-0. 0040mg/kg, the average recovery is 84.3 % -101.1% , the relative deviation is 1.5% -2.7%. The analytic results are satisfactory. |
