气相色谱-质谱法检测土壤中挥发性有机物研究

Determination of volatile organic compounds in soil by gas chromatography-mass spectrometry

目的探究气相色谱-质谱法检测土壤中挥发性有机物的效果。方法采用气相色谱-质谱法对某工厂24组土壤样品进行检测。结果不同区域土壤中挥发性有机化合物(Volatile Organic Compounds,VOCs)的种类和浓度存在一定差异,该工厂土壤中含有苯系物、氯代烃等挥发性有机物,结果满足土壤中VOCs的监测要求。结论实验证明,气相色谱-质谱法能准确检测出土壤中的挥发性有机物种类、成分和含量,检测结果准确性较高,值得推广应用。

Objective To explore the effectiveness of gas chromatography-mass spectrometry in detecting volatile organic compounds in soil.Methods Gas chromatography-mass spectrometry was used to detect 24 groups of soil samples from a certain factory.Results There are certain differences in the types and concentrations of VOCs in soil from different regions.The soil of this factory contains volatile organic compounds such as benzene series,chlorinated hydrocarbons,and esters,which meet the monitoring requirements for VOCs in soil.Conclusion Experimental results have shown that gas chromatography-mass spectrometry can accurately detect the types,components,and contents of volatile organic compounds in soil,with high accuracy in the detection results.It is worth promoting and applying.
