| 摘 要： | 应用连续加速溶剂萃取(ASE)技术以4种不同的溶剂分别对2个土壤、 2个沉积物以及1个页岩样品进行3次抽提.结果表明,第1次得到的多环芳烃(PAHs)组分占据了全部含量的一半以上,甲苯是4种有机溶剂中抽提效率最高的;对于给定样品,连续ASE所得到的PAHs来源指标都相似,表明应用这些指标进行PAHs来源判定的可行性.

| Abstract: | Polycyclic aromatic hydrocarbons (PAHs) in two soils, two sediments and an shale from the Pearl River Delta were extracted by sequential accelerated solvent extraction (ASE) with each of four different organic solvents for three times. PAHs in the first extract accounts for more than half of their total contents, and toluene displays the best extraction performance among the four employed solvents. For a given sample the source diagnostic ratios of PAHs in sequential ASE with each solvent are very similar, suggesting the validity of those ratios in source judgement by different extraction methods. |
