Abstract: A comprehensive analytical method based on high performance liquid chromatography-ultravioiet-fluorescence detection (HPLC-UV-FL) has been established for the determination of bisphenol A (BPA), nonylphenol (NP) and octylphenol (OP) in beverages with different samples and concentrations. Clean-up of samples was performed on an OASIS HLB solid extraction cartridges (6 mL, 200 mg). The method was successfully applied to the investigation of residual bisphenol A, nonylphenol and octylphenol in the beverages (mineral waters and soft drinks) available in commercial markets in Beijing. Recoveries for bisphenol A, nonylphenol and octylphenol at different spiked levels were ranged from 91.08% to 103.19% with relative standard deviations of 0.5% to 5.49%. The method is simple with good reproducibility and selectivity, and high sensitivity.
