摘要
对PM2.5的检测主要是根据颗粒物的力学、光学、电学等物理性质与颗粒物的数量、质量或其他参量之间的关系,通过相应的检测设备进行的。本文对常用滤膜称重法、光散射法、β射线吸收法、微量振荡天平法等PM2.5检测方法的工作原理及各自的优缺点进行综述,为PM2.5检测提供技术指导,便于PM2.5检测者根据实际的检测需求选择合适的检测方法。
The detection of PM2.5 is completed with relevant equipment based on the relationship between the mechanical,optical,electrical or other physical properties of particulate matter and the quantity,mass or other parameters of particulate matter.The working principles and characteristics of main PM2.5 detection methods are reviewed in this paper,such as filter membrane weighing method,light scattering method,βray absorption method,tapered element oscillating microbalance method and so on.
