PROBLEM TO BE SOLVED: To maintain a deodorizing performance of acidic, basic, and sulfur-based gas, and to provide a composite odor deodorizing having an excellent deodorizing performance for an aldehyde-based gas that has been difficult to deodorize by a conventional method. Provide the agent. [MEANS FOR SOLVING PROBLEMS] The present invention provides (1) a composite odor deodorant characterized in that an acidic salt of p-aminobenzoic acid, an inorganic acid, and bromine and / or bromide are supported on a porous body, (2) The supported amount is 0.5 to 20 parts by weight of p-aminobenzoic acid or acidic salt, 1 to 20 parts by weight of inorganic acid, 1 of bromine and / or bromide with respect to 100 parts by weight of the porous body. The composite odor deodorizer according to (1) above, which is ˜20 parts by weight. [Selection figure] None |
