摘要
运用基于气体分子扩散理论自制的被动采样器,结合Saltzman法,通过该采样器在室内外进行曝露采样检测NO2的含量.该采样器在空气中曝露24个小时后,测定空气中的NO2浓度可达n×10-3mg/m3,与TH-110C型便携式直流大气采样器测定结果比较,误差在30%以内.
A passive sampler based on a gas molecular diffusion theory, combining with the Saltzman method, was used to determine the nitrogen dioxide of indoor and outdoor environment. The passive sampler could determine nitrogen dioxide at several 10^(-3) mg/m^3 by exposure of 24 hours, and the error was within 30% .
