摘　　要：制备以聚2,6-二苯基对苯醚(Tenax)为吸附剂的针阱微萃取(NTME),并利用NTME耦合气质联用(GC/MS)建立了一种快速提取和检测空气中乙叉降冰片烯(ENB)的方法。当气体中的ENB浓度为4.14~828 mg/m^3,提取体积为100μL时,气体中ENB的浓度与色谱响应值呈线性相关,相关系数R2为0.9965,方法检出限为0.022 mg/m^3。该方法用NTME提取气样体积仅需100μL,提取时间<2 min,操作便捷,适用于环境空气中的挥发性有机物ENB的快速监测。A needle trap microextraction(NTME)filled with Tenax was successfully prepared.A rapid extraction and determination of ethylidene norbornene(ENB)in air by NTME-GCMS was established.The results showed the chromatographic responses had a linear relationship with concentrations of EN8 with a correlation coefficient of 0.9965 and a detection limit of 0.022 mg/m^3 when the concentration of ENB in the gas varied from4.14 mg/m^3 to 828 mg/m^3 with a constant extraction volume of 100μL.The NTME method was convenient to extract air samples with a volume of only 100μL within 2 min,which was suitable for rapid determination of volatile organic ENB in ambient air.
