| Abstract: | 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. |
