- 1. An active carbon for deodorization, which comprises a deodorizing functional group fixed to a graphitic six-membered ring on the surface of an active carbon through a silanol bond.
- 7. A process for the preparation of an active carbon for deodorization, which comprises steps of forming a hydroxyl group on graphitic active carbon on a surface of the active carbon by an oxidation treatment, and condensing said hydroxyl group formed on the surface of the active carbon with a silicon compound having a hydrolyzable group and a deodorizing functional group, to thereby fix the deodorizing functional group to the surface of the active carbon through a silanol bond.
