摘　　要：动态顶空 气相色谱/质谱法监测土壤中苯系物及卤代烃,优化了动态顶空的平衡时间、解吸温度、解吸时间等条件。在最优条件下,各组分的校准曲线线性相关系数为 0.9947~0.9992,加标回收率为 86.2 %~116.6 %,相对标准偏差为 1.2 %~4.5 %,线性关系及重现性良好、准确度及精密度较高。25 kinds of bens and volatile halogenated hydrocarbons in soil were monitored with dynamic headspace coupled with gas chromatography/mass spectrometry. Under the optimized conditions, components acquired linear correlation coefficient of 0.9947~0.9992, recovery of 86.2 %~116.6 % and relative standard deviation of 1.2 %~4.5 %.
