摘要
总结了底泥中多环芳烃(PAHs)提取的处理流程和国内外多种提取方法,比较了几种在我国较为常用的提取方法的效率。同时还提出了PAHs分离纯化的方法和步骤,并指出了提取过程中影响实验回收率的几个因素。
The procedure of PAHs extraction in sediments and several extraction methods were summarized here. Extraction effi-ciency of different methods frequently used in China was also compared. The procedure of separating PAHs were brought forward in this thesis. Meanwhile, some important issues were raised which can be responsible for the recovery ratio of PAHs extraction.
