In this work, the aerosol wall loss was investigated in 2.5 and 5.8-m³cubic-shaped Teflon film chambers filled with ambient air. The natural change in the particle size distribution was measured using a scanning mobility particle sizer in a dark environment. The rate of aerosol wall loss was obtained from the deposition theory suggested by Crump and Seinfeld (1981). The measured rates of aerosol wall loss were in a good agreement with the theoretical and experimental values given by McMurry and Rader (1985), implying that the electrostatic effect enhances particle deposition on the chamber wall. The significance of aerosol wall loss correction was demonstrated with the photochemical reaction experiments using the ambient air. 한국대기환경학회 Aerosol Wall Loss in Teflon film Chambers Filled with Ambient Air Article 2 Journal of Korean Society for Atmospheric Environment, v.20, no.E1, pp.35 - 41 Journal of Korean Society for Atmospheric Environment 20 E1 35 41 ART000939585 Aerosol Wall loss Smog chamber Teflon film Ambient air
