| 中文摘要: |
| 采用气相色谱-三重四极杆串联质谱（GC-MS/MS）法测定硫化胶中双酚A含量，研究样品前处理条件对测试结果的影响，并探讨GC-MS/MS测试的优化条件。结果表明：采用丙酮配置双酚A质量浓度为10～1 000 μg·L-1的标准工作溶液，所得工作曲线相关因数＞0. 992，线性相关性良好；该方法检出限为0. 1 mg·kg-1，定量限为0. 3 mg·kg-1，0.5，1和5 mg·kg-1三个双酚A添加量下平均回收率在90. 9%～105.1%范围内，相对标准偏差均＜5%。GC-MS/MS法适用于轮胎不同部位双酚A含量的检测。 |
| 英文摘要: |
| Bisphenol A content in vulcanizates was determined with gas chromatography-triple quadrupole tandem mass spectrometry（GC-MS/MS） method. The effects of sample pretreatment conditions on the test results were studied，and the optimal test conditions of GC-MS/MS were discussed. The results showed that by using acetone to prepare a standard solution with a mass concentration of bisphenol A of 10～1 000 μg·L-1，the correlation coefficient of the obtained working curve was larger than 0. 992 and the linear relationship was good. The detection limit of this method was 0. 1 mg·kg-1，the quantitation limit was 0. 3 mg·kg-1，the average recoveries were in the range of 90.9% ～105.1% at three tested addition levels of bisphenol A （0. 5，1 and 5 mg·kg-1），and the relative standard deviation was less than 5%. GC-MS/MS method was suitable for the analysis of bisphenol A content in different parts of tires. |
