CESIUM-CONTAINING LAYERED DOUBLE HYDROXIDE COMPLEX AND WASTE SOLIDIFIED BODY USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a cesium-containing layered double hydroxide complex capable of forming a waste solidified body which can be conserved in such a state that the cesium absorbed highly selectively is stable for a long period.SOLUTION: A cesium-containing layered double hydroxide complex contains: a layered double hydroxide complex containing a layered double hydroxide and a ferrocyanide metal compound provided to at least either interlayers or a surface of the layered double hydroxide; and the cesium absorbed to the ferrocyanide metal compound contained by the layered double hydroxide complex.
