摘　　要：将沸石咪唑酯骨架材料(ZIF-67)制成固相微萃取涂层,结合气相色谱-质谱联用仪(GC-MS),建立了一种快速分析跑道面层成品中苯的方法。实验优化条件为:萃取温度60°C,萃取时间60 min。该方法测定样品中苯的线性范围为10 ng·g^(-1)~500 ng·g^(-1),检出限为0.9 ng·g^(-1),定量限为2.9 ng·g^(-1)。方法应用于实际跑道面层样品中苯的检测,加标回收率为85.2%。该方法可用于跑道面层成品中苯的快速检测,具备多样的研究可能性。A rapid method for the determination of benzene in plastic runways was developed with a zeolitic imidazolate framework material(ZIF-67)as solid-phase microextraction(SPME)coating by gas chromatography-mass spectrometry(GC-MS).The optimal conditions were as follows:extraction temperature:60°C,extraction time:60 min.Under the opti⁃mal conditions,the calibration curve for benzene was linear in the range of 10 ng·g^(-1)-500 ng·g^(-1) with limit of detection and limit of quantitation of 0.9 ng·g^(-1) and 2.9 ng·g^(-1),respectively.This method was applied in the analysis of benzene in a plas⁃tic runway sample with recoveries of 85.2%.This method can be used for the rapid detection of benzene in plastic runways,and has various research possibilities.
