摘　　要：建立了超声波萃取—气相色谱/质谱(GC/MS)联用测定轮胎制品中多环芳烃(PAHs)的分析方法。优化了超声波萃取条件,采用MS的选择离子检测方式对PAHs进行定性定量分析。结果表明,16种PAHs的平均加标回收率为75.4%～88.0%,相对标准偏差(n=5)为0.66%～11.90%,方法检出限在1.0～4.0ng/mL。A method for the determination of polycyclic supersonic extraction coupled with gas chromatography-mass aromatic hydrocarbons （PAHs） m rubber goods usmg spectrometry was developed. The optimum conditions for extraction were studied in detail. Using the selected iron monitoring （SIM） mode of the MS system,the qualification and quantification of PAHs could be done. The recoveries and relative standard deviations were among 75.4 % to 88.0% and 0.66% to 11.90% ,respectively,and the detection limits ranged from 1.0 ng/mL to 4.0 ng/mL.
