Summary:PURPOSE:To treat harmful gas for a long time at a low cost by allowing a gas-permeable metal porous product of iron and/or manganese impregnated with water of hydrogen peroxide containing alkali to come in contact with a gaseous product containing harmful gas. CONSTITUTION:A metal powder consisting mainly of iron and/or manganese applied to an organic polymer porous product such as polyurethane foam, is sintered in an unoxidized atmosphere. Next, the porous product 12 is deposited in a reaction tank 11, and a liquid 13 prepared by adding any amount of water of hydrogen oxide and alkali from a tank for addition of hydrogen peroxide 19 and a tank for addition of alkali 20 to an adjustment tank 18, is sprayed to the porous product 12 from a nozzle 15 through a pump 14. Next, a gaseous product containing harmful gas is introduced into the reaction tank 11 by an air blower fan 17 to permit a Fenton oxidation reaction.
