| 中文摘要: |
| 介绍轮胎中多环芳烃的危害以及来源，采用气质联用结合内标法测定了不同品牌和规格的全钢载重子午线轮胎主要部位受限制的8种多环芳烃的含量。各部位样品的超声波萃取液经气质联用的选择离子监测模式采集数据后，根据内标法建立的标准曲线计算其中的多环芳烃含量。本方法灵敏、准确、可靠且适用于轮胎中各部位多环芳烃含量的测定。 |
| 英文摘要: |
| The hazards and sources of polycyclic aromatic hydrocarbons(PAHs) in tire were introduced,and the content of 8 appointed PAHs in major parts of different brands and tire sizes was measured by gas chromatography/mass spectra (GC/MS) combined with the internal standard method.The data of each sample which was prepared by ultrasonic extraction was collected by selected ion monitoring of GC/MS,and then the content of PAHs was calculated according to the standard curve established by internal standard method.This method was sensitive,accurate,reliable and suitable for the determination of PAHs in various parts of tire. |
