摘要
本文用扩散管差分法和多种叠层滤膜法测量大气中颗粒物铵盐和气态氨.扩散管差分法可以有效分离测量颗粒物铵盐和气态氨.避免了采样时惰性滤膜上颗粒物硝酸铵分解的人为影响.
Measurements of paniculate ammonium and gaseous ammonia in ambient air were studied by denuder difference and filter packs. The denuder difference experiment can be used to measure particulate ammonium and gaseous ammonia in the atmosphere while avoiding losses of particulate ammonium by sampling artifacts.
