| 中文摘要: |
| 采用超高效液相色谱-串联质谱法测定水中痕量双酚A，水样经预处理后，以BEHC18超高效液相色谱柱分离，在质谱电喷雾离子源负离子多反应监测模式下测定。方法在0.200 μg/L～10.0μg/L范围内线性良好，相关系数r为0.999 2，方法检出限为0.06μg/L，空白及实际样品加标回收率为87.4％～114％，RSD为3.6%～7.4%。 |
| 英文摘要: |
| A rapid analytical method for determination of bisphenol A(BPA) in water samples was developed. 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 ionization with BEHC18column(1.7μm,2.1mm×50mm)using acetonitrile and water as mobile phase in a gradient elution mode. The limit of determination was 0.06μg/L. The average recoveries of blanks and real samples were at the range of 87.4%～114% for the spiked levels of 0.200μg/L and 10.0μg/L. The relative standard deviations (RSDs) of spiked samples (n=6) were at the range of 3.6%～7.4%. |
