| Abstract: | The extraction of alkane pollutants from soil was carried out by the supercritical fluid extraction (SFE) and followed by GC-MS identification. The main factors affecting the extraction efficiency were discussed. It has been demonstrated that the analytical SFE tech- nique has more advantages over the conventional Soxhlet method, and may be effectively used for the extraction of alkane pollutants from complex environrnental samp1es. |
