| Abstract: | A method to simultaneously analyze 9 organophosphorus pesticide residues in vegetables using solid phase extraction(SPE) and capillary gas chromatography with flame photometric electron capture detector was developed(GC-FPD).Vegetable samples were extracted with ethyl acetate under the assistance of high-speed homogenization and ultrasonic.The extract was condensed,transferred into acetone-n-hexane(2∶8,v/v),then purified through combined SPE tubes.The combination of SPE tubes which includes CARB,SCX and FL from up to down gives good purified result.The recoveries of most target analytes range between 60.1% and 93.4% at two different spiking levels.The method determination limits was among the range of 1.6 μg/kg～5.0 μg/kg. |
