Objective To develop a method for the determination of bisphenol F, bisphenol A and tetrabromobisphenol A in materials for drinking water supply system. Methods The materials for drinking water supply system were ground, then were extracted by methanol with ultrasonic extraction, the extract were quantitatively analyzed for bisphenol F, bisphenol A and tetrabromobisphenol A by liquid chromatography-tandem mass spectrometry (LC-MS-MS)method under the optimal conditions of the instrument. Results The calibration curves of the above-mentioned three compounds showed a good linearity in the range of 15.0-500kg/L and the correlation coefficients were more than 0.9960. The limits of quantification (LOQ) of the method were 3.5-62kg/kg. The spiked recoveries ranged from 84.0%-119.3% with the relative standard deviations of 1.4%-12.2%. Bisphenol F was detected in ABS plastic pipe with the content of 1.67kg/g. Bisphenol A was detected in 7 samples with the content of 0.114-120kg/g. Tetrabromobisphenol A was not detected in all the samples. Conclusion The method is sensitive and accurate, and is applicable to the determination of bisphenol F, bisphenol A and tetrabromobisphenol A in the materials used for drinking water supply system.
