Determination of phthalic acid esters in soil by gas chromatography-tandem mass spectrometry
摘要
Abstract
A method based on gas chromatography-tandem mass spectrometry (GC-MS/MS) was developed for the determination of phthalic acid esters (PAEs) in soil. The soil sample was extracted by dichloromethane-acetone (1:1, v/v) with an ultrasonic instrument, and the extract was cleaned up with a Florisil column. The identification and quantification of the ana-lytes were carried out in the multiple reaction monitoring (MRM) mode after the GC separation on an HP-5MS column (30 m ×0. 25 mm ×0. 25μm). The eight point calibration curves showed a good linearity for all the congeners (0. 997 3 - 0. 997 6 ). The limits of detection ( LODs) ranged from 0. 1 to 0. 5 μg/kg. The relative standard deviations ( RSDs) were not more than 14. 3% and the spiked recoveries were in the range of 72. 9% - 106. 2%. The developed analytical method is rapid and accurate, and suitable for the determination of PAEs in soil.关键词
