Method for removing cesium with cesium adsorption agent and a method for manufacturing the same, and cesium adsorbent .

摘要

[Problems] high adsorption performance of cesium concentration by solid-liquid separation after cesium adsorption is easy, it is possible to effectively implement the volume reduction, and further there is no problem of the dissolution of the cyanide to the soil , it provides a cesium adsorbent. A formula M. ^1. _x. M. ^2. _y. [Fe (CN). _6. ] NH. _2. O (in the formula, M. ^1. Monovalent alkali metal, M. ^2. Polyvalent transition metal, x, y, n each x = 1~2, including y = 1~2, n = 0 to 3.) iron cyano metal compound represented by, cesium adsorbent. BACKGROUND.
