摘要
To provide an agent for removing a halogen series gas and a method for removing a halogen series gas which is excellent in a removing ability of removing the present halogen series gas in a low concentration area, which prevents an adsorbent from generating heat, and which is capable of reducing formation of a solid waste.;A method for removing a halogen series gas, which comprises bringing a gas to be treated which contains at least one member selected from the halogen series gas group consisting of F2, Cl2, Br2, I2, and compounds which generate a hydrogen halide or hypohalogeneous acid upon hydrolysis, into contact with a granule comprising, based on the total mass of the granule, from 45 to 99.85 mass% of an alkali metal salt, from 0.1 to 40 mass% of a carbonaceous material, and from more than 0 mass% to 15 mass% of an alkaline earth metal salt, in the presence of water.
