摘　　要：建立了加速溶剂提取-凝胶渗透色谱净化和气相色谱-质谱联用快速分析土壤中16种多环芳烃的新方法。方法的检出限、定量限分别为1.1-12μg/kg、3.7-40μg/kg。16种 PAHs 的回收率为76.6％-96.8％，相对标准偏差为2.9％-9.5％。应用于多个环境样品的分析测试，结果满意。Based on accelerated solvent extraction, gel permeation chromatography and gas chromatography-mass spectrometry, a novel method was developed for the simultaneous determination of 16 polycyclic aromatic hydrocarbons in soil samples. The limits of detection and the limits of quantitation were 1. 1-12 μg/kg and 3. 7-40 μg/kg for 16 polycyclic aromatic hydrocarbons, respectively. The average recoveries of all the compounds were 76. 6%-96. 8%, and relative standard deviations were 2. 9%-9. 5%. This method was fast, simple and easy to operate. The method has been used to determine 16 polycyclic aromatic hydrocarbons in real soil samples with satisfactory results. It can be applied in routine soil analysis.
