Title:
METHOD FOR REMOVING CESIUM IONS IN AQUEOUS SOLUTION EMPLOYING MAGNETIC PARTICLES
Document Type and Number:
WIPO Patent Application WO/2013/094711
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a method for removing cesium ions, whereby cesium ions present in aqueous solution can be efficiently separated and recovered within a brief period of time, while decreasing the number of manual operating steps and reducing the amount of cesium waste products. In this method for removing cesium ions, the cesium ions in an aqueous solution containing cesium are adsorbed by a water-soluble adsorbent, the water-soluble adsorbent having adsorbed the cesium ions is transformed into a water-insoluble magnetic complex in the presence of magnetic particles, and the magnetic complex is magnetically separated to remove the cesium ions in the aqueous solution.
