Abstract: Objective To establish a rapid analytical method for determination of 16 kinds of polycyclic aromatic hydrocarbons (PAHs) in massage oil by molecular imprinting solid phase extraction (MIP-SPE) with gas chromatography-mass spectrometry (GC-MS). Methods The samples were diluted with hexane and 16 kinds of PAHs were adsorbed by MIP-PAHs-SPE and detected by GC-MS with external standard method after being cleaned up with primary secondary amine solid phase extraction (PSA SPE). Results This method had a good linearity in the range of 50-500 μg/L with correlation coefficients among 0.9870~0.9993. The recoveries of all PAHs were in the range of 75.5% to 117.2% at the spiked levels of 100~1000 μg/kg in samples, and the relative standard deviations (RSDs) were less than 14.9%. The limits of detection (LOD) were 0.3~4.1 μg/kg. Conclusion The established method is simple, rapid and accurate, which can be used for the determination of 16 kinds of PAHs in massage oil.
