A accelerated solvent extraction ( ASE ) and online purification method to determine the organo-phosphrous pesticide residues in frozen dumplings was established .With high speed , stability , reliability and easy operation, this method obtained good linearity for determining 15 pesticides with concentration between 0.05-0.5μg/mL (the correlation coefficients (r) were all greater than 0.998 5).The detection limits ranged from 0.006 mg/kg to 0.05mg/kg.The average recoveries of organophosphrous pesticides were between 84.88%and 107.1%. The relative standard deviations for 15 organophosphrous pesticides were between 1.92%and 1.40%.
