Abstract

In the conventional picture of simple salt solutions, atomic ions shun the air/water interface and are more likely to be found in the bulk of the liquid. Hence, simple inorganic salts such as sodium halides should be excluded from the water surface. However, recent computational and experimental studies show that atomic ions such as halides can be present in the surface region, in some cases even at enhanced concentrations. Halide ions at the surfaces of atmospheric aerosol particles may plan an important role in controlling oxidant levels in the marine boundary layer of the atmosphere.
