摘要
地气测量是采用液态捕集剂,高效富集地气中纳米微粒,以高灵敏度的ICP-MS分析元素特征的监测方法。针对传统大气颗粒物监测方法,面临大范围高分辨率空气质量监控仍显乏力,固态滤膜本底浓度较高且不均一的技术难题,在研究大气颗粒物物化特征的基础上,结合地气测量法,提出一种新的大气颗粒物元素浓度采样方法。根据成都地区条件实验,新方法能有效富集大气颗粒物,并能较准确反应环境变化特征。
Geogas measurement technology was a measurement of monitor technology,which used liquid collector extraction gas,gathers nanoparticle in the geogas rapidly and analyzed the element characteristics by high sensitive ICP-MS. The interference factors of atmospheric particulate matter ＇s collection were very complicated and solid membrane filter was inhomogenous with high background. As a result,it＇s hard to monitor atmospheric emergency or a high resolution air quality in wide range. Combining geogas method,a new observation approached was investigated to study elements of atmospheric particles. The new method could effectively enrich atmospheric particulate matter and accurately response to the various characteristics of environment.
