| 摘 要： | 分别采用索氏萃取和超声萃取两种样品前处理方法,将水泵橡胶密封件介质机体中多环芳烃（Polycyclic Aromatic Hydrocarbons,简称PAHs）和其他干扰物质分离开;利用气相色谱-质谱联用仪对萃取液中的PAHs进行定量分析,研究了不同萃取方法对水泵橡胶密封件中多环芳烃种类、回收率和分布的影响,发现两种萃取方法所得的PAHs种类是相同的,但采用索氏方法萃取出的PAHs总量、回收率以及极性和溶解度不同的PAHs质量浓度均高于超声萃取法.试验对比结果表明：在GC-MS分析条件下,索氏萃取法在提取水泵橡胶密封件中PAHs的能力上优于超声萃取法;超声萃取在高沸点PAHs的提取方面具有优势.因此,需根据被测目标PAHs的性质及样品情况的不同选择不同的样品前处理方法.

| Abstract: | The samples collected from the pump rubber seals were extracted by Soxhlet Extraction Method and Ultrasonic Extraction Method respectively.PAHs were separated from the impurities in the pump rubber seals.The extracted liquids were determined by gas chromatography-mass spectrometry.The impact on the concentration,recovery and distribution of PAHs extracted by different extracting methods from pump rubber seals were studied.It was found that the PAHs categories were the same by the two extraction methods,but ... |
