| Abstract: | This article introduced the technology of extracting PAHs from sediments by microwave.In optimized experimental conditions,the 16 kinds of PAHs content in the sediment was determined by using meteorological chromatography-mass spectrometry method,and verified the feasibility of experimental methods by spiked recoveries.The results showed that microwave digestion and silica gel purification column sample pre-treatment method was simple,safe,sample volume,short time-consuming solvent saving,pollution lower.Sample recovery was 67.353% ~101.666%. |
