  • Process for the separation and purification of medical isotopes
    Patent number: 10704123
    Abstract: The invention provides a method for isolating medical isotopes, the method having the steps of dissolving titanium nuclear targets to create a solution; contacting the solution with a resin so as to retain the isotopes on the resin and generate an eluent containing titanium; contacting the isotope-containing resin with acid of a first concentration to remove impurities from the resin; and contacting the isotope-containing resin with an acid of a second concentration to remove isotope from the resin.
    Type: Grant
    Filed: July 3, 2019
    Date of Patent: July 7, 2020
    Assignee: UCHICAGO ARGONNE, LLC
    Inventors: Michael Alexander Brown, Jerry A. Nolen, Jr., David Alan Rotsch
