摘　　要：随着现代工业生产各种有机物排放量日益增加和空气、土壤、地下水、固废污染日益严重,现在对场地修复、整理的需求持续增强,在场地修复过程中,挥发性有机物的治理效果及修复过程中对周边的影响,需要可靠的监测手段予以保证得到可靠的数据,本文通过建立一种可以长期连续逸散采样监测21种挥发性有机物的热脱附-气相色谱质谱仪的方法,为VOCs监测提供更多的测试选择,以符合不同的需求,达到不同的效果。With the increasing emissions of various organic substances from modern industrial production and the increasingly serious pollution of air,soil,groundwater and solid waste,the demand for site restoration and finishing now continues to grow.In the process of site restoration,the effect of VOCs management and the impact of the restoration process on the surrounding area need reliable monitoring means to ensure reliable data are obtained.This paper provides more testing options for VOCs monitoring by establishing a thermal desorption-gas chromatography-mass spectrometer method that can monitor 21 kinds of VOCs with long-term continuous fugitive sampling to meet different needs and achieve different results.
