Two metal organic framework materials were investigated to determine the removal efficiency and capacity of MOF materials for krypton recovery from air at non-cryogenic temperatures. Our two bed breakthrough measurements on NiDOBDC and a partially fluorinated FMOFCu indicate these materials can capture and separate parts per million levels of Xe and Kr from air and, with a two-bed system, separate Xe from Kr. In a two-bed system, the he removal efficiency and adsorption capacity for Kr on these two MOFs were further increased Xe was removed in the first bed. This shows a promising future for MOFs in a radioactive nuclides separation from spent fuel.
