| Abstract: | The main organic components of the precipitation in Guanting Reservior are qualitatively determined by GC MS. The origins of organic pollutants are discussed. By the investigation of the two extraction methods and extraction time, it is found that extracting the precipitation by Soxhlet extraction method in 8 hours has the highest efficiency. The suitable conditions of solid phase extraction are obtained. Polycyclic aromatic hydrocarbons (PAHs) and organic acids of the precipitation are enriched and purified by SPE method. And 80 kinds of PAHs , 26 kinds of acids and 6 kinds of diacids are detected. |
