| 中文摘要: |
| 采用气相色谱-质谱联用（GC-MS）测定轮胎胶料中的18种多环芳烃（PAHs）含量。结果表明：用甲苯作萃取剂、60 ℃下超声波萃取80 min、用硅胶固相萃取柱纯化处理样品，在采用离子监测模式扫描、程序升温、脉冲不分流进样的条件下进行GC-MS测试，样品的18种PAHs含量加标回收率为68%~104%。该方法操作简便，准确度高，检测限低。 |
| 英文摘要: |
| The content of 18 types of PAHs in the tire rubber compounds was determined using gas chromatography-mass spectrometry (GC-MS).The test sample was firstly swelled in the extraction solvent，toluene，at 60 ℃ with ultrasonication for 80 minutes.The extracted solution was purified by silica solid phase extraction column.Then the GC-MS test was carried out using ion monitoring mode scanning，programmed temperature and pulsed-splitless sample injection.The spiked recovery ranged from 68% to 104%.The method is simple，accurate，and has a low detection limit. |
