METHOD FOR COLLECTING TUNGSTEN COMPOUNDS |
摘要 |
[Object] To efficiently recover tungsten from an object containing tungsten by a simple treatment process using a microorganism with reduced environmental load. [Solution] A method for recovering a tungsten compound is provided which includes the step of preparing a tungsten compound solution in which tungsten-containing polyatomic ions are dissolved, by eluting the metal component of an object containing tungsten into an alkaline solution; the adsorption step of adsorbing the tungsten-containing polyatomic ions to a microorganism by introducing the microorganism to the tungsten compound solution and adjusting the tungsten compound solution to an acidic level; and the collecting and washing step of collecting the microorganism to which the tungsten-containing polyatomic ions are adsorbed and washing the microorganism. |
