A novel magnetic covalent organic framework (Fe₃O₄@COF-SCU1) was prepared via a facile method, and was used for the magnetic solid phase extraction (MSPE) of eight polycyclic aromatic hydrocarbons (PAHs) from dahongpao tea soup, which were analyzed by high performance liquid chromatography-UV (HPLC-UV). Fe₃O₄@COF-SCU1 was characterized by electron scanning microscope, electron transmission microscope, X-ray diffraction, nitrogen isothermal adsorption and desorption, and Fourier transform infrared. In this experiment, the composition of Fe₃O₄@COF-SCU1, the adsorption and elution conditions of MSPE were systematically optimized, and the qualitative and quantitative analysis method of PAHs was established. Under the optimal conditions, all the 8 PAHs obtained a good linear relationship, and the correlation coefficients were larger than 0.998 7. The detection limit (LODs, S/N=3) and quantitative limit (LOQs, S/N=10) were in the range of 0.10~0.40 ng/mL and 0.33~1.34 ng/mL, respectively. The proposed method for analysis of PAHs was successfully applied to the analysis of dahongpao tea soup. The standard recovery and relative standard deviation were in the range of 74%~106% and 1.20%~8.50%, respectively. The results showed that Fe₃O₄@COF-SCU1 could be used for easily and rapidly extraction of trace PAHs.
