液体浸出-顶空进样-便携GC/MS法测定土壤中挥发性有机物

Determination of volatile organic compounds in soil by liquid leachinig and headspace and portable gas chromatograph-mass spectrometer

建立了液体浸出-顶空进样-便携气相色谱/质谱法测定土壤中的挥发性有机物(VOCs)的方法。结果表明,该方法简单、方便、准确,24种挥发性有机物的实际样品加标回收率可达60%以上。本方法采用便携气质进行定性和定量,可以应用于土壤污染事故应急监测的挥发性有机物现场检测。

Set the determination method of volatile organic compounds （VOCs） in soil by liquid leachinig and headspace and portable gas chromatograph-mas spectrometer. The results show that the method is simple, conve- nient and accurate. The spiked recoveries of twenty-four kinds of VOCs come to be above 60%. The qualitative and quantitative description was taken out by using portable gas chromatograph-mass spectrometer, and the method can be used for the soil pollution accident emergency monitoring.
