摘要
应用加速溶剂萃取气相色谱-质谱联用法测定土壤中16种多环芳烃。确定了二氯甲烷-丙酮(体积比1:1)作为提取溶剂,方法检出限为0.10～3.90ng/g,加标回收率为72.6%～123.5%。方法检出限较低,精密度好,适用于土壤样品中多环芳烃的分析。
A method for the determination of 16 polycyclic aromatic hydrocarbons （PAHs） in soils by gas chromatography-mass spectrometry （GC-MS） with accelerated solvent extraction （ASE） sample preparation was developed.A mixture solution of methylene chloride/acetone （1：1,V/V） was selected as the optimum extraction solvent through the experiments.The detection limits of the method for PAHs were 0.10 ～ 3.9 ng/g and the recoveries were 72.6% ～ 123.5%.The method provides the advantages of lower detection limits,good precision and is suitable for the determination of PAHs in soils.
