Determination of chlorimuron-ethyl residue in soybean by solid phase extraction-high performance liquid chromatography-mass spectrometry
摘要
Abstract
A solid phase extraction-high performance liquid chromatography-mass spectrometry method was established for determination the residue of chlorimuron-ethyl herbicide in soybean.Samples were extracted by methanol with ultrasonic,then liquid-liquid partitioned with normal hexane and purified by solid phase extraction. The sample was quantitatively analyzed by high performance liquid chromatography and qualitatively analyzed by high performance liquid chromatography-mass spectrometry.Results showed that： a good linear range from 0.1- 200.0μg/L with correlation coefficient of above 0.9997 （n = 3）was obtained.The extraction recovery were 92.6% 95.2% and the relative standard deviation were 1.27%-2.64%.The limit of detection was10.0μg/kg （S/N = 3）.The described method was simple,sensitive and accurate.关键词
