In this paper, two benchmark MOFs, Ni/DOBDC and HKUST-1, are studied for Xe and Kr adsorption using a dynamic column breakthrough method.  We report Xe and Kr capacities and selectivities for the two MOFs and the results are compared with those of an activated carbon and simulation results.2    In addition, low concentration Xe and Kr adsorption from air experiment are performed on the two typical MOFs and a fluorinated MOF, FMOF-Cu, to exam the potential of using these MOFs in a real treatment for radioactive air stream.  Our paper provides the first experimental study on the low concentration Xe and Kr separation from air using MOFs, which are promising to be used in spent nuclear fuel treatments.
