ELECTROCHEMICAL OCCLUSION REMOVAL METHOD AND DEVICE OF METAL ION IN METAL ION-CONTAINING AQUEOUS SOLUTION USING POROUS ALUMINUM ELECTRODE

摘要

PROBLEM TO BE SOLVED: To provide an electrochemical occlusion removal method capable of separating and removing efficiently metal ion of a radioactive nuclide contained in polluted water.SOLUTION: Electrolysis in which a porous aluminum material is used as a cathode in radioactive metal ion-containing aqueous solution is carried out, and metal ion in the metal ion-containing aqueous solution is occuluded into the porous aluminum material in a reduction atmosphere. After finish of the electrolysis, moisture is removed from the porous aluminum material having metal ion occuluded therein, and the porous aluminum material having metal ion occuluded therein is stored.SELECTED DRAWING: None
