Abstract:
     Impurities of heavy metal ions and/or organic impurities in the solution can be effectively adsorbed, through forming chelate, by ion-exchanger which is consisted of a compound selected from a series of organic sulfides and sodium salts of organic phosphonate ester carried on granular activated carbon or diatomaceous earth. The agent causes no undesired effect upon the solution and the products.
