摘要：
A new method was developed to determine the presence of polycyclic aromatic hydrocarbons (PAHs) in edible fats and oils. Samples are dissolved in petroleum ether, and PAHs are adsorbed onto a molecularly imprinted solid-phase extraction (MIPSPE) cartridge and eluted with ethyl acetate. After evaporation of the solvent, PAHs were re-dissolved in acetonitrile and analyzed by RP-HPLC with fluorescence detection. The detection limits of PAHs were 0.04-0.66 mu g/kg and the recovery rates ranged from 56.0 percent to 109.1 percent. The total contents of PAHs in edible oils were 18.00-639.96 mu g/kg. The developed method was effective due to its high specificity for PAHs.
