摘　　要：采用气相色谱串联质谱联用法测定环境空气颗粒物中多环芳烃。样品与无水硫酸钠混合后,用正己烷、丙酮(1∶1,V/V)在加速溶剂萃取仪上以10.3 MPa、80℃提取10 min,用串联质谱检测器进行分析,16种多环芳烃的回收率在70.5%~107%之间。该法得到了良好的分离效果。The analytical methods of polycyclic aromatic hydrocarbons(PAHs)in Particulate Matters are studied by ASE-GC-MS/MS.The sample is blend by Na2SO4,with acetone,Hexane(1∶1,V/V)on acceleration solvent extraction meter by 10.3 MPa,80℃;withdraws 10 min,carries on the analysis with the MS/MS detector,The returns-ratio between 70.5%~107%.This method has high sensitivity.
