Abstract
An object of the present invention is to provide a method for removing cesium ions, where cesium ions in an aqueous solution can be efficiently separated and recovered in a short time, the number of human-performed steps can be decreased as much as possible, and the amount of cesium-containing waste can be reduced. The method for removing cesium ions of the present invention can remove cesium ions in an aqueous solution, comprising adsorbing cesium ions by a water-soluble adsorbent in a cesium-containing aqueous solution, transforming said water-soluble adsorbent having adsorbed thereto cesium ions into a water-insoluble magnetic composite in the presence of a magnetic particle, and magnetically separating said magnetic composite.
