Title:
CESIUM ADSORPTION AGENT, PRODUCTION METHOD THEREFOR, AND CESIUM REMOVAL METHOD USING CESIUM ADSORPTION AGENT
Document Type and Number:
WIPO Patent Application WO/2015/083688
Kind Code:
A1
Abstract:
Provided is a cesium adsorption agent that exhibits high cesium adsorption performance, that makes it possible to effectively concentrate and reduce volume as a result of it being easy to perform solid-liquid separation after cesium adsorption, and that does not cause problems by leaking cyanogen into soil and the like. The cesium adsorption agent comprises an iron cyanometallate compound that is represented by the formula M1
xM2
y[Fe(CN)6]·nH2O (in the formula, M1 is a monovalent alkali metal, M2 is a polyvalent transition metal, x = 1 to 2, y = 1 to 2, and n = 0 to 3).
