A new magnetic sorbent named as ferromagnetic fluorinated graphene (FG@Fe₃O₄) was prepared for extraction and enrichment of 10 kinds of fluorine-containing pesticides in tea soups, which were then detected by gas chromatography tandem triple quadrupole mass spectrometer (GC-MS/MS). The transfer rate of fluorine-containing was also investigated. Due to the π electrons and F atoms, FG@Fe₃O₄ could form π-π conjugation and fluorous-fluorous interaction with fluorine-containing pesticides, and the magnetic sorbent displayed excellent adsorption performance for 10 kinds of fluorine-containing pesticides. Scanning electron microscopy, X-ray diffraction, Fourier transform infrared spectrometry and vibrating sample magnetometer were used to characterize the sorbents. The main parameters, such as sorbent amount, desorption solvent, extraction time were investigated. The adsorption properties of different sorbents and the recycle times of FG@Fe₃O₄ were also investigated. Under the optimum conditions, the linear relations were good in the corresponding concentration range with the correlation coefficients of more than 0.998. The method limits of detection (S/N=3) and method limits of quantitation (S/N=10) ranged from 0.3 μg/kg to 6.0 μg/kg and 1.0 μg/kg to 20.0 μg/kg, respectively. The average recoveries ranged from 71.2% to 108.4% and the intra-day precisions were 2.6%-8.7% at three standard spiked levels. This developed method was successfully applied for the detection of 10 tea soup samples, among which flubendiamide was detected in 2 samples, flufenoxuron was detected in 2 samples, and triflumizole was detected in one sample. The transfer rate of different fluorine-containing pesticide from teas to infusion was different.
