摘　　要：目的建立输配水材料中双酚A的测定方法,并测定饮水输配水材料中双酚A含量。方法用液相色谱-串联质谱（LC/MS/MS）的方法,选择最佳的仪器条件,对30种输配水材料进行了测定。结果双酚A在0-100ng/ml浓度范围内呈良好的线性关系,相关系数达到0.9994,检出限为5μg/kg,回收率在90%-99%之间,相对标准偏差在1.8%-5.0%之间。在检测的30个样品中,检出含有双酚A的样品有9个,检出率为30%;离子交换树脂双酚A含量高达1.82mg/kg。结论本实验所建立的方法快速、灵敏（检出限达5μg/kg）,选择性好,结果准确可靠。Objective To develope the determination methods for bisphenol A in drinking water system components. Methods 30 samples were quantitatively analyzed by liquid chromatography-tandem mass spectrometry （LC/MS/MS）.Results Bisphenol A was linear in the range 0 - 100ng/ml and the linear correlation coefficient reached 0.9994. The minimum detection limit was 5μg/kg. The spiked recoveries were from 90% to 99%, and the RSD were between 1.8 - 5.0% . Bisphenol A was measured in nine out of thirty samples. The detected ratio was 30% and the maximum was 1.82mg/kg. Conclusion The method was quick, sensitive and specific.
