Hydrogen sulfide is dehydrogenated to generate a HS group and an S group. The HS group is oxidized to generate sulfuric acid, which is bonded to a metal. The S group is polymerized with a CH.sub.3 S group to generate methyl trisulfide or methyl tetrasulfide, which is adsorbed to an adsorbent. Methyl mercaptan is dehydrogenated, for example, to generate a CH.sub.3 S group. A portion of the CH.sub.3 S group is oxidized to generate methanesulfonic acid, which is bonded to a metal. Another portion of the CH.sub.3 S group is polymerized with the CH.sub.3 S group itself to generate methyl disulfide, at least a portion of which is adsorbed to an adsorbent. Still another portion of the CH.sub.3 S group is polymerized with the S group to generate methyl trisulfide or methyl tetrasulfide, which is physically adsorbed to an adsorbent. In this manner, malodor components including hydrogen sulfide and methyl mercaptan can efficiently be removed without producing or release of harmful secondary products. A simple-structure, compact deodorizing apparatus including appropriate metal oxide catalyst and an adsorbent material suitable for achieving the above deodorizing functions is incorporated in a toilet bowl.
