| titleOfInvention | Manufacture of adsorbent from kanuma soil |
| abstract | PURPOSE: To obtain adsorbent having good adsorbability and less pulverisability by adhering triiron tetraoxide to the surface of Kanuma aoil as a raw material. n CONSTITUTION: Kanuma soil, used for horticultural purpose, etc., is first regulated to a proper grain size distribution, and an appropriate amount of the weel-grained Kanuma soil is dipped in a ferrous sulfate solution and then after several minutes is added an alkali, e.g., aqueous ammonia, etc., to adjust its pH to 11 or more, whereupon ferrous hydroxide is precipitated and on further oxidation with stirring, the iron hydroxide is changed into triiron tetraoxide and adhered to the surface of Kanuma soil. Then, the Kanuma soil is washed with water and then heated for drying to oxidize the triiron tetraoxide into ferric oxide of reddish orange color. The Kanuma soil so treated as an adsorbent is free of the formation of membranous substances on its surface and also less pulverisable and thus serves as good adsorbent having good adsorbability. n COPYRIGHT: (C)1980,JPO&Japio |
