The influence of ammonia and carbon dioxide on the sorption of basic (alkaline) organic pollutants onto indoor surfaces

Abstract

"Sorptive interactions with indoor surfaces strongly influence indoor exposure to organic pollutants. The surface capacity of a volatile amine, a basic compound, is influenced by a common indoor gaseous acid, CO₂, and base, NH₃. Experimental results show that CO₂ tends to cause a mineral surface (zirconium silicate) and carpet to store more amine, but NH₃ tends to decrease the surface capacity of zirconium silicate, carpet and latex-painted gypsum board. Hypotheses testing along with the studies of surface characterizations and molecular interactions with an amine suggests that sorption of an amine to these indoor materials is primarily a surface phenomenon. However, dissolution of an amine and acid-base chemistry in the bulk surface water may also contribute to the overall sorptive capacity of carpet at high relative humidity. This fundamental research is a first step towards better understanding indoor exposures to amines such as nicotine, pyridine, etc."--Abstract, page iii.
