▎ 摘　　要

A new analytical method by graphene-reinforced hollow fiber liquid-phase microextraction combined with high-performance liquid chromatography fluorescence detection was developed for the determination of bisphenol A and 4-tert-butylphenol in bottled juices. Several important experimental parameters were studied to get optimal extraction conditions for the analytes. Under the optimized conditions, the method showed a good performance having a linear response in the range from 0.05 to 10.0 ng mL(-1) with the correlation coefficients (r) of 0.9965-0.9994 and limits of detection of 0.01 ng mL(-1). The relative standard deviations were in the range from 6.4 to 7.2 % at the spiked concentration of 1.0 ng mL(-1). The method combines the high-adsorption capacity of graphene and the excellent clean-up performance of hollow fiber liquid-phase microextraction and has been successfully applied to the analysis of the analytes in bottled juice samples.
