环境空气中不同挥发性有机化合物的离线吸附采集方法综述

A Review of Off-line Adsorption Methods of Different Volatile Organic Compounds in Ambient Air

环境空气中有机化合物按照挥发性不同可分为:VOCs(包括HMHC和OVOCs)、IVOCs和SVOCs。在环境空气中VOCs和IVOCs一般呈气态,SVOCs由于挥发性较低,会同时呈气态和颗粒态存在。由于不同化合物的存在状态和分子组成的不同,其相应的离线吸附采集方法也各不相同,本文主要综述了环境空气中不同挥发性有机化合物的离线吸附采集方法。

Organic compounds in ambient air can be divided into VOCs(including HMHC and OVOCs),IVOCs,and SVOCs according to their volatility.In ambient air,VOCs and IVOCs are generally gaseous,while SVOCs are both gaseous and granular due to their low volatility.The off-line adsorption methods of different volatile organic compounds in the ambient air are different due to their different state of existence and molecular composition.In this paper,off-line adsorption methods of dofferent volatile organic compounds in ambient air were reviewed.
