Abstract
The activated carbon comprises activated carbon impregnated with one or more chromium compound, one or more heavy metal salt and one or more alkali metal iodide. The heavy metal salt may be a salt of Fe, Co, Ni, Cu, Ag or Au, and the activated carbon may also be impregnated with iodine. Although the compounds present undergo undesired reaction with each other and sometimes with the carbon, the impregnated activated carbon can be used to provide a compact filter (e.g. in respiratory devices) for adsorbing radioactive iodine and compounds thereof as well as other harmful gases (e.g. chlorine cyanide) from air.
