摘要
PROBLEM TO BE SOLVED: To obtain a removing agent for removing sulfur oxide or sulfur oxide/ hydrogen sulfide mixed gas present in air in a concentration harmful to the human body with high efficiency by a dry detoxification/removal method to lower the same to a concentration exerting no effect on the human body, and a removing method using the same. SOLUTION: The removing agent is prepared by adding 0.01-5 wt.%, preferably 0.1-1 wt.% of potassium iodide to activated carbon as a catalyst and further adding 0.01-0.5 wt.% of a heavy metal compound thereto as a cocatalyst if necessary. The removing agent is brought into contact with air containing sulfur oxide or sulfur oxide/hydrogen sulfide mixed gas harmful to the human body by a packed column system to remove sulfur dioxide and hydrogen sulfide with high efficiency.
