Abstract
A process of removing a volatile organic compound (VOC) from a gaseous environment, involving contacting a gaseous feedstream containing one or more VOC's, such as an odoriferous compound, an irritant, a contaminant or pollutant, for example, formaldehyde, with a sorbent under conditions sufficient to reduce the concentration of the VOC's in the gaseous feedstream. The sorbent is comprised of a functionalized graphene prepared by amination of graphene oxide. The sorbent is regenerated by adsorbate desorption under mild conditions of air flow. The process can be run through multiple adsorption-desorption cycles in a single fixed bed or swing bed configuration, and is applicable to purifying indoor air and ventilation air as well as reducing pollutants in industrial waste gas streams.
