  • Methods to remove organic and/or inorganic compounds from water
    Patent number: 11319220
    Abstract: Disclosed are methods to remove organic and/or inorganic compounds (e.g., contaminants) from water containing organic and/or inorganic compounds, involving contacting the water with an effective organic and/or inorganic compounds removing amount of hemoglobin/Fe3O4 composite where the compounds in the water adsorb onto the hemoglobin/Fe3O4 composite, and removing (e.g., using a magnet since the composite is magnetic) the hemoglobin/Fe3O4 composite from the water.
    Type: Grant
    Filed: May 18, 2020
    Date of Patent: May 3, 2022
    Assignee: The United States of America, as represented by The Secretary of Agriculture
    Inventors: Matthew Essandoh, Rafael A. Garcia
  • MODIFIED PROTEIN ADSORBENTS FOR CONTAMINANT REMOVAL
    Publication number: 20210060523
    Abstract: Disclosed are adsorbent compositions including a recoverable and reusable polypeptidylated hemoglobin iron composite and methods of using the compositions to adsorb and/or remove contaminant compounds from water involving contacting the water with an effective amount of the composition to remove the contaminant compounds.

  • Methods for Flocculating Suspended Solid Particles or Dissolved Solids Using Biobased Renewable Flocculants
    Publication number: 20190300399
    Abstract: Disclosed are methods for aggregating suspended solid particles (e.g., kaolin) or dissolved solids in an aqueous medium, involving treating the aqueous medium with an effective amount of a flocculant (to aggregate the solids) to form aggregated solid particles or aggregated solids, and optionally separating the aggregated solid particles or aggregated solids from the aqueous medium; wherein the flocculant is a polymerized protein (e.g., polymerized hemoglobin or polymerized BSA which are proteins that have been polymerized by crosslinking).
