PURPOSE:To obtain an adsorbent high in flocculating strength and having high adsorbing capacity, by using a substance prepared by insolubilizing tannin with a multivalent metal salt as the adsorbent. CONSTITUTION:As an adsorbent for adsorbing a malodorous source such as ammonia or carbon disulfide, one prepared by insolubilizing tannin such as gallnut or mangrove with a multivalent metal such as beryllium or manganese is used. The obtain multivalent metal salt of tannin is high in flocculating strength as well as high in adsorptivity and used as the excellent adsorbent. |
