PURPOSE:To provide deodorizing effect extremely effective for a malodorous component in a gaseous phase by using a copper ion-containing compound as an effective component. CONSTITUTION:This deodorant is composed of a copper ion-containing compound. When said copper ion is divalent and the anionic functional group bonded thereto is an acidic functional group excepting a carboxyl group and a halogen ion, said compound is effective for basic malodorous gas (especially, ammonia gas). For example, there is an inorg. compound selected from copper sulfate, copper nitrate, copper phosphate and copper chromate as a representative example and an organometal compound such as copper p-styrene sulfonate or a polymer containing the same as a copolymer component is also used. When the copper ion is divalent and the anionic functional group is basic, this compound is effective for acidic or neutral malodorous gas (especially, hydrogen sulfide, ethyl mercaptane). For example, copper hydroxide or basic copper carbonate is designated. |
