大豆、花生及粮油中56种农药残留量的检测方法
Detection Methods of 56 Pesticide Residues in Soybean, Peanut and Grain Oil
摘要
Abstract
In order to study the pesticide residues in the source samples of grain and grain oil,a multiresidue analytical method for the rapid determination of 56 pesticide residues in soybean,peanut and grain oil was established by gas chromatography/triple quadrupole mass spectrometry(GC/MS/MS).The MS/MS detection parameters and presample treatment were optimized.The samples were extracted by acetonitrile,freezing,centrifuge,and purification treatment by series C18/PSA solid phase extraction column and detected by gas chromatography/triple quadrupole mass spectrometry (GC/MS/MS).The 56 pesticides in linear range showed good linear relationship,the linear coefficient was greater than 0.99.The detection limit (LOD) was 0.001-0.005 mg·kg-1,the validation test results showed that the recovery of the compounds was between 62％ -116％ and relative deviation (RSD) was between 0.82％-14.5％.The method has good reproducibility,high precision and simplicity suitable for a variety of pesticide residues detection as soybean,peanut,grain oil and most plant sources.关键词
