<p>PROBLEM TO BE SOLVED: To provide a deodorizing material excellent in adsorption performance of acetaldehyde and formaldehyde. SOLUTION: This deodorizing material is produced by depositing at least one kind of hydrazine salts or metal salt hydrazine double salts on at least one kind of a carrier selected from porous clay, silica gel, silica flour or active alumina. The obtd. deodorizing material has improved air permeability and a handling property and shows excellent deodorizing performance for mal odors such as methylmercaptan and an org. solvent. The producing method of the deodorizing material is also provided.</p> |
