Abstract
A modified active carbon material for adsorption of airborne lower aldehydes. The activated carbon is impregnated with triethylenediamine (TEDA) and has a copper deposition. A filter media is formed from a method of preparing triethylenediamine (TEDA) activated carbon with deposited copper for removal of toxic formaldehyde from the environment, such as a process of making surface modified granular activated carbon media that is highly efficient in removing formaldehyde.
