<P>PROBLEM TO BE SOLVED: To provide an inexpensive deodorization filter quickly adsorbing, efficiently decomposing and cleaning food odor or malodor (ammonia, trimethylamine, hydrogen sulfide, methylmercaptan, dimethyl disulfide) contained in a large quantity in excretory odor. <P>SOLUTION: The deodorization filter is formed of a substance carrying metal phthalocyanine complex, polycarboxylic acid and metal salts on activated carbon-mixed paper. Activated carbon quickly and strongly adsorbs malodor of ammonia, trimethylamine, hydrogen sulfide, methylmercaptan, dimethyl disulfide or the like, and metal phthalocyanine complex, polycarboxylic acid and metal salts effectively decompose and clean them. <P>COPYRIGHT: (C)2008,JPO&INPIT |
