Deodorizing Composition and Deodorizing Resin Composition Containing Iron (II) Compound US5703152A

A liquid deodorizing composition containing an iron (II) compound and a chelating agent dissolved in water is known (JP-A-60-145143 and JP-A-211240). In use, the deodorizing composition is sprayed over a source of bad odors. The known deodorizing composition containing an iron (II) compound and a chelating agent is reactive with bad odor substances such as ammonia, amines, hydrogen sulfide, mercaptans.

Thus, when air containing odorous substances is contacted with the composition, the substances are reacted with the deodorizing composition and are removed from the air to give odorless air.
