Methods for rapid isolation of radionuclides (e.g., 68 Ga) produced using a cyclotron and methods for recycling of the parent isotope (e.g., 68 Zn) are disclosed. In one version of the method, a solution including a radionuclide (e.g., 68 Ga) is created from a target including cations (e.g., 68 Zn). The solution including the radionuclide is passed through a first column including a sorbent comprising a hydroxamate resin to adsorb the radionuclide on the sorbent, and the radionuclide is eluted off the sorbent. The cations (e.g., 68 Zn) are recovered from a recovery solution that has passed through the first column by passing the recovery solution through a second column including a second sorbent comprising a cation exchange resin. |
