Determination of Organophosphorus Amino Acids Herbicides Residues in Fruits and Vegetables by Underivatization/Liquid Chromatography-Tandem Mass Spectrometry
An underivatization/liquid chromatography-tandem mass spectrometric method was developed for the determination of 4 organophosphorus amino acids herbicides in fruits and vegetables.Samples were firstly extracted with water-dichloromethane solution,then purified by dichloromethane liquid-liquid extraction with HLB solid phase extraction column,and finally determined by liquid chromatography-mass spectrometry.At the optimal conditions,the linear correlation coefficients(,r,) for all compounds were more than 0.996 in the concentration range of 0.010-0.200 mg/L.The limits of detection and quantitation of the method were 0.01 mg/kg and 0.05 mg/kg,respectively.The average recoveries for all compounds at spiked levels of 0.050,0.100 and 0.200 mg/kg ranged from 72.2% to 109%,with relative standard deviations(RSDs,,n ,= 6) of 2.2%-11%.The method is rapid,simple,sensitive and accuracy,and it could be used for the determination and confirmation of organophosphorus amino acids herbicides in fruits and vegetables.
