PURPOSE:To obtain a deodorant clay mineral which can efficiently remove odorous components of ammonia or amino compds. by substituting transition metal elements or aluminum for a part of magnesium atoms in clay mineral containing magnesium silicate. CONSTITUTION:A part of magnesium atoms in the porous crystalline structure of clay mineral containing magnesium silicate, such as sepiolite essentially comprising magnesium silicate hydrate, is replaced by aluminum or transition metal elements selected from Ti (atomic number 22) to W (atomic number 74). The obtd. deodorant clay mineral can efficiently remove mixed odor such as ammonia and amino compds. containing various kinds of odorous components. |
