Abstract
Dry-scrubbing media compositions, methods of preparing same, and methods of use are provided. The compositions contain activated alumina and potassium carbonate. Optionally, activated carbon and other impregnates, such as sulfates of group 1A metals, are included in the compositions. The compositions exhibit improved efficiency and capacity for the removal of compounds such as chlorine or sulfur dioxide from an air-stream. The compositions are particularly useful for reducing or preventing the release of toxic gaseous compounds from the areas such as petroleum storage areas, refineries, drinking water systems, sewage treatment facilities, swimming pools, hospital morgues, animal rooms, and pulp and paper production sites.
