  • Separation of uranium isotopes using anion exchangers
    Patent number: 4112045
    Abstract: Uranium-235 is efficiently concentrated using a solution containing uranium-238 and uranium-235 by passing a solution containing uranium (VI) complex anions through a body of an anion exchange material to adsorb uranium (VI) complex anions on a portion of the anion exchange material and then passing a solution of a reducing agent through the anion exchange material thus retaining uranium in the form of the uranium (VI) complex anions to elute the uranium ions while reducing the uranium (VI) complex anions to uranium (IV) complex ions.
