A rapid analytical method for determination of bisphenol A(BPA)in water samples was devel-oped.Water samples were pretreated and then analyzed by ultra performance liquid chromatography electrospray tandem mass spectrometry (UPLC-MS/MS)in multiple reaction monitoring mode via negative electrospray ioni-zation with BEH C18 column(1.7 μm,2.1 mm ×50 mm)using acetonitrile and water as mobile phase in a gradi-ent elution mode.The limit of determination was 0.06 μg/L.The average recoveries of blanks and real samples were at the range of 87.4%~114% for the spiked levels of 0.200 μg/L and 10.0 μg/L.The relative standard deviations (RSDs)of spiked samples (n=6 )were at the range of 3 .6% ~7 .4%.
