Abstract
Provided is a filter for removing a sulfur-containing-gas (1), which removes the sulfur-containing-gas by being brought into contact with the sulfur-containing-gas in a gas flow path, the filter including a former filter (11) disposed on an upstream side of the gas flow path, and a latter filter (12) disposed on a downstream side of the gas flow path, wherein the former filter (11) includes a first material for removing a sulfur-containing-gas, the first material including a porous support, and iodine which is supported on the porous support, and is produced by catalytic pyrolysis of ammonium iodide at a thermal decomposition ratio of 80% or more by use of the porous support as a catalyst, and the latter filter (12) includes a second material for removing a sulfur-containing-gas, the second material including an activated carbon fiber, and an alkali component which is supported on the activated carbon fiber.
