Abstract
A method for evaporatively concentrating a radioactive metal nuclide, including: a first evaporative concentration process in which a radioactive solution formed by dissolving a radioactive metal nuclide in an acidic aqueous solution is heated to evaporate a solvent in the radioactive solution so as to obtain a concentrated liquid containing the radioactive metal nuclide; and a second evaporative concentration process in which a low-boiling organic solvent having a lower boiling point than water is added to the concentrated liquid, and the concentrated liquid is heated to induce azeotropic boiling of the concentrated liquid and the low-boiling organic solvent so as to obtain an evaporative concentrate of the radioactive metal nuclide.
