Determination of bisphenol A in chemical fiber by LC-MS/MS
A high performance liquid chromatography-tandem mass spectrometry(LC-MS/MS)method for the determination of bisphenol A in chemical fibers is established by studying the influence of different pretreatment conditions on the determination of bisphenol A in chemical fibers.Using acetone dichloromethane as the solvent,the sample is extracted by ultrasonic extraction,filtered,and analyzed by LC-MS/MS.The results show that bisphenol A shows a good linear relationship in the range of 10.0～200.0 μg/L,the correlation coefficient is 0.999,the detection limit of is 0.10 mg/kg,the recoveries for spiked samples are 80.63％～95.46％,and the relative standard deviations range from 2.74％to 5.81％.The method is simple,rapid,stable and suitable for the determination of bisphenol A in synthetic fibers.
