ABSTRACT:
The present invention proposes light-weight and easy-to-handled deodorizing material that has a large contact area with bad smell-causing gas as well as better deodorizing performance and also that enjoys a smooth circulation of that gas with a lower permeation resistance. A single-faced corrugated fiberboard made of a cellulose-based substance is allowed to contain ferrous sulfate, which is subsequently oxidized into basic ferric sulfate.
