Title:
RADIOACTIVE CESIUM DECONTAMINATING AGENT AND METHOD FOR PRODUCING SAME, AND METHOD FOR REMOVING RADIOACTIVE CESIUM
Document Type and Number:
WIPO Patent Application WO/2014/038713
Kind Code:
A1
Abstract:
Provided is a method for producing a decontaminating agent particle, which enables the easy and high-productivity production of a decontaminating agent particle that can decontaminate a radioactive substance with high efficiency, has high environmental resistance, is suitable for the treatment of a large amount of the radioactive substance, and can be used in a radioactive substance decontamination system or the like. Provided is a method for producing a radioactive cesium decontaminating agent, which comprises: a step of suspending a magnetic particle in a solvent and coating the magnetic particle with a monomer or polymer of an organic substance to form a precursor; a step of adding an aqueous ferrocyanide solution and an aqueous solution containing at least one transition metal to a suspension containing the coated precursor while applying strong shear force to the suspension to produce a radioactive cesium decontaminating agent; and a step of removing water from a slurry containing the radioactive cesium decontaminating agent.
