PROBLEM TO BE SOLVED: To provide a method for separation, stabilization, and immobilization of elements of multi-nuclides in which cesium and strontium are adsorbed and separated, and then the separated elements are stabilized and immobilized, an adsorbent used for this method, and a method for adsorption and removal of cesium and strontium.SOLUTION: A method for separation, stabilization, and immobilization of elements of multi-nuclides comprises the steps of: (1) adsorbing elements of multi-nuclides including cesium and strontium by bringing a liquid to be treated into contact with an adsorbent comprising zeolite (B) to which an insoluble ferrocyanic compound (A) is added; and (2) calcining the adsorbent obtained by the step (1) to produce a ceramic-like solidified body. |
