摘　　要：采用热脱附/冷阱捕集/气相色谱-质谱法对土壤中挥发性有机物（17种）进行测定。以17种化合物（卤代烃和苯系物）为标准绘制标准曲线，各目标化合物的相关系数为0.9973-0.9998；检出限为0.02-0.13μg/kg；加标平均回收率为85.2%- 98.5％ ；RSD为3.17%-5.56%。本方法分析时间短、操作简单、灵敏高，测定结果较为满意。The seventeen volatile organic compounds（VOCs） in soil were detected by thermal desorption-cold trap-GC-MS, and the standard curves were drawn by the seventeen VOCs （halogenated？hydrocarbon and benzene series） as standards. The correlation coefficients of every compounds were 0.9973-0.9998; the detection limit were 0.02-0.13μg/kg; the recovery rate were 85.2%-98.5%; the RSD were 3.17%-5.56%. The advantages of the method were short analysis time, simple operation, high sensitivity, and the results were satisfactory.
