摘　　要：The determination of 7 bactericidals residues,including chlorthalonil,dichlofluanid,tolylfluanid,captan,folpet,captafol and deltamethrin,in foods by using on-line gel permeation chromatography(GPC) coupled with gas chromatography-mass spectrometry(GC-MS).Bactericidal residues were extracted with acetonitrile,and cleaned up by ENVI-Crab,LC-NH2 column and GPC,respectively.The analysis of 7 bactericidals residues was performed by GC-MS.The average recoveries of analytes were range of 75%-120% with RSD of 3.5%-10.3%.The determination of 7 bactericidals residues,including chlorthalonil,dichlofluanid,tolylfluanid,captan,folpet,captafol and deltamethrin,in foods by using on-line gel permeation chromatography(GPC) coupled with gas chromatography-mass spectrometry(GC-MS).Bactericidal residues were extracted with acetonitrile,and cleaned up by ENVI-Crab,LC-NH2 column and GPC,respectively.The analysis of 7 bactericidals residues was performed by GC-MS.The average recoveries of analytes were range of 75%-120% with RSD of 3.5%-10.3%.
