A study of sulfur dioxide in photochemical smog. I. Effect of SO2 and water vapor concentration in the 1-butene/NOx/SO2 system.

摘要: There is an appreciable chemical interaction between SO2 and photochemical smog which depends on the concentration of water vapor. The rate decay greatly increased in presence smog. With 0.75 ppm SO2, a light-scattering aerosol produced dry systems at 22 55% relative humidity (RH). Aerosol not observed until after NO2 peak has been reached NO fallen to very low value. formation corresponds time region most rapid decrease profile. In 65% RH or with smaller amounts no light scattering observed, but percentage disappearing greater. relatively results general slowing down reactions. containing vapor concentrations comparable those found atmosphere, inhibiting influence reaction less pronounced. However, ...
