| 中文摘要: |
| 采用气相色谱-质谱联用法测定橡胶中18种多环芳烃（PAHs）的含量，研究提取溶剂、色谱柱类型、内外标法及内标加入顺序对PAHs定量分析的影响。结果表明：以甲苯作为最优提取溶剂，采用专用色谱柱测定的18种PAHs含量结果偏差最小；使用内标法定量的结果更为准确；内标加入顺序对PAHs定量分析影响较小；在使用SH-5MS色谱柱对PAHs含量进行监测时，可以使用乙酸乙酯作为提取溶剂先行对PAHs含量进行筛查。 |
| 英文摘要: |
| The content of 18 kinds of polycyclic aromatic hydrocarbons（PAHs） in rubber was determined by gas chromatography-mass spectrometry，and the effects of extraction solvent，chromatographic column type，internal and external standard methods，internal standard addition order on the quantitative analysis of PAHs were studied.The results showed that using toluene as the optimal extraction solvent and a dedicated chromatographic column to determine the content of 18 kinds of PAHs resulted in the smallest deviation.The results quantified using internal standard method were more accurate.The internal standards addition order had a small impact on quantitative analysis of PAHs.When monitoring the content of PAHs，using SH-5MS chromatographic column，ethyl acetate could be used as an extraction solvent to screen for PAHs content first. |
