  • Patent number: 10723635
    Abstract: The present invention provides for the use of a metal-organic framework (MOF) in removing particular chemical species or compounds, in particular oxy-anions, from a liquid or liquid stream. In some embodiments, the MOF is a Zr-based MOF, such as NU-1000, and the oxy-anions that are removed include, include, for example, oxy-anions of selenium, including selenite (SeO32?) and selenate (SeO42?); oxy-anions of antimony, including oxy-anions in either the Sb[III] (antimonite) or the Sb[V] (antimonate) redox state; and oxy-anions of lead, including oxy-anions in either the Pb[II] or the Pb[IV] redox state, such as Pb(OH)62?, Pb(OH)64?, PbO32?, and PbO22?. The Zr-based MOF, including NU-1000 can be used to remove these oxy-anions from various liquid streams in industrial processes such as a nuclear and fossil fuel power plants, including the latter's flue gas desulfurization system.

  • Patent number: 10308527
    Abstract: The present invention provides a metal-organic framework (MOF) for use in removing particular chemical species or compounds from a liquid. In particular, the present invention provides an MOF having a molecular formula of Zr6(?3-O)4(?3OH)4(OH)4(H2O)4(TBAPy)2, wherein TBAPy is 1,3,6,8-tetrakis (p-benzoic-acid)pyrene, (known as NU-1000) for use in complexing selenate or selenite from a liquid or liquid stream. Further, the selenium based oxy-anions are removed to concentrations below that specified for wastewater discharge by the U.S. Environmental Protection Agency for flue gas desulfurization operations in the fossil fueled electric power generation industry. Such water treatment results are achieved even in the presence of competing sulfate anion challenges and at elevated temperatures comparable to condensate cooling water.

  • Patent number: 10272279
    Abstract: A method of using a metal organic framework (MOF) comprising a metal ion and an at least bidendate organic ligand to catalytically detoxify chemical warfare nerve agents including exposing the metal-organic-framework (MOF) to the chemical warfare nerve agent and catalytically decomposing the nerve agent with the MOF.
