摘　　要：建立了顶空气相色谱质谱法测定跑道面层颗粒中二硫化碳含量的分析方法。实验优化了顶空条件,在优化条件下二硫化碳具有良好线性,校准曲线相关系数为0.993 1,方法检出限为0.002μg·g^(-1),在低、中、高三个加标水平下的平均回收率为93.6%~98.5%,相对标准偏差(RSD,n=6)为4.1%~8.6%。A method for determination of carbon disulfide in runway surface particles by headspace gas chromatography was established. Under the optimized headspace conditions, the calibration curve has a good linearity, the correlation coefficient of calibration curve is 0.993 1, and the detection limit of the method is 0.002 μg·g^(-1). The average recoveries at low,medium and high spiking levels ranged from 93.6% ~98.5%, with the relative standard deviations(RSD, n=6) 4.1% ~8.6%.
