Methods of capturing and immobilizing radioactive nuclei with metal fluorite-based inorganic materials

摘要

Methods of capturing and immobilizing radioactive nuclei with metal fluorite-based inorganic materials are described. For example, a method of capturing and immobilizing radioactive nuclei includes flowing a gas stream through an exhaust apparatus. The exhaust apparatus includes a metal fluorite-based inorganic material. The gas stream includes a radioactive species. The radioactive species is removed from the gas stream by adsorbing the radioactive species to the metal fluorite-based inorganic material of the exhaust apparatus.

1. A method of synthesizing a metal fluorite-based inorganic material, the method comprising:
charging a reaction vessel with a solution comprising an aluminum precursor and a fluorine precursor; adding a precipitating agent to the solution comprising the aluminum precursor and the fluorine precursor; and isolating an aluminum (Al)-rich fluorite precipitate.
