摘要
Abstract
A rapid and accurate method based on accelerated solvent extraction liquid chromatography tandem mass spectrometry ( LC-MS/MS) was developed for the determination of 9 kinds of pesticides in soil. The analytes were extracted by accelerated sol?vent extraction using acetonitrile as the extraction solvent. The extract was concentrated by evaporation. Qualitative and quantita?tive analysis for the analytes was carried out by the multiple reaction monitoring mode after the chromatographic separation using acetonitrile-water solution as mobile phase. The linear range of detection for nine pesticides was between 0. 5-500 μg/kg, and the limits of detection were between 0. 2-2.0 μg/kg. The recoveries and relative standard deviations were 90.0% -105.0% and 1.0% -5. 9% , respectively. This method is rapid, sensitive and suitable to the determination of pesticides in soil.关键词
