PURPOSE:To obtain an adsorbing material having good air permeability and easy handleability as the adsorbing material, by forming aluminum dihydrogen tripolyphosphate into a sheet-like form by using a fibrous substance. CONSTITUTION:As the adsorbing material, aluminum dyhydrogen tripolyphosphate 3 is formed into a sheet-like form alone or together with another adsorbent such as activated carbon or silica gel by using fibrous substances 1, 2 comprising pulp fiber or org. synthetic fiber. The obtained adsorbent sheet has good air permeability and shows inherent adsorbing capacity of aluminum dihydrogen tripolyphosphate easily as well as has wide use. |
