摘要

With the aid of wind-tunnel experimentai setup, the possibilities that nitrogen monoxide (NO) is oxidized to nitrogen dioxide (NO2) in various environments were stucied, which include indoor, outdoor and darkroom conditions. By comparing their effects, a conclusion can be drawn that NO can be oxidized to NO2 in indoor environment with a low rate, and micro amountof ozone, propylene and methane can accele rate the reaction:2NO+O2→NO2. The initial concentration of NO has effect on the oxidation rate. When the initial concentration of NO ranges between 500 and 900 μg/L, natural iogarithm of iinitial rate and natural logarithm of initial concentration have a good linear relation, so do In(1/[NO]) and the time (t). Besides that,the possible oxidation mechanism of indoor NO has also been studied.
