氯苯类化合物在大气中分布特征探究
|
摘要
建立环境空气和有组织废气排放模拟污染源,以玻璃纤维滤膜+玻璃棉和活性炭为吸附材料采集大气中氯苯类化合物,使用气相色谱法测定各组分,考察氯苯类化合物在大气气相和颗粒物中的分布特征。结果显示,环境空气和固定污染源有组织排放废气中一氯代至四氯代苯类各组分主要分布在大气气相中,颗粒物中少有分布,说明现行环境监测方法以固体吸附剂采集测定大气中的氯苯类化合物可行。
In this paper,chlorobenzenes from ambient air and simulated stationary pollution source were collected by glass fiber filter membrane plus glass wool,activated carbon as the adsorption material,and determined by gas chromatography. The distribution characteristic of chlorobenzenes in gaseous phase and particulate matter were discussed. The results showed that from monochlorobenzene to tetrachlorobenzene compounds in ambient air or stationary pollution source,each monomer was mainly distributed in gas phase,and rarely in particulate phase,confirming that current environmental monitoring method for chlorobenzenes determination by using solid adsorbent was feasible.
