Iron oxides are a reactive component of air, water and soil. The adsorption of several atmospheric gases including SO@sub 2@, HNO@sub 3@ and CO@sub 2@ as a function of relative humidity has been examined on iron oxide particle surfaces. Results from several techniques including a newly designed XPS reactor/analysis system will be presented. These studies show that adsorbed water plays an important role in the surface chemistry of iron oxide particles with these molecules.
