摘要： An anti-contamination method for the simultaneous determination of 16 polycyclic aromatic hydrocarbons (PAHs) in tea was developed using gas chromatography-tandem mass spectrometry. In this study, three transitions for each PAHs were monitored at multi-reaction monitoring (MRM) mode and pseudo-MRM mode to improve the reliability of the developed method. The PAHs were extracted using acetonitrile and then cleaned up by simultaneous dispersive solid-phase extraction (D-SPE) and liquid-liquid extraction (LLE). A mixture of adsorbents that contain primary-secondary amine, octadecylsilane and florisil was applied for the D-SPE cleanup. The solvent used for LLE was n-hexane with a 1:2 (v/v) ratio of acetonitrile extracts and n-hexane. Loss of PAHs occurred during sample preparation because of incomplete extraction of PAHs from the acetonitrile extracts into n-hexane with the LLE treatment. Isotopic surrogate standards were used to calibrate for the loss of PAHs during sample preparation. For the 16 PAHs, linear calibrations with coefficients R (2) a parts per thousand yenaEuro parts per thousand 0.99 were obtained. The limits of quantifications of the 16 PAHs were < 3 mu g kg(-1). The recovery rates of samples spiked with 10, 50 and 200 mu g kg(-1) of analytes varied from 77 to 116 %, with relative standard deviations of < 13 %. The developed method was used to determine the PAHs in 46 tea samples.
