An automated online gel chromatography/gas chromatography-mass spectrometry(GPC/GC-MS) method was established for the determination of 11 phenoxy acid herbicide residues in fruits.The sample was extracted with acetone-hexane and derivatived with butanol sulfuric acid,then the extract was purified by Florisil solid phase extraction column and analyzed by automated online GPC/GC-MS under selected ion monitoring(SIM) mode.The results indicated that the calibration curves of 11 pesticides were linear in the range of 0.01-1.0 mg/L ,with correlation coefficients of 0.998 7-0.999 9.The average recoveries of 11 phenoxy acid herbicide in fruits at spiked levels of 0.02-0.10 mg/kg ranged from 66%to 112% with relative standard deviations(RSDs) of 3.4%-11.5%.The method has high sensitivity for 11 phenoxy acid herbicides with quantitation limits of 7-10 μg/kg.The method was simple,rapid,sensitive and effective,and could meet the requirement for the simultanous determination of 11 pesticide residues in fruits.
