  • Lipophilic guanidinium compounds for removal of oxyanions from aqueous solutions
    Patent number: 11001554
    Abstract: Methods for removing an oxyanion from an aqueous source containing said oxyanion, comprising contacting said aqueous source with an aqueous-insoluble hydrophobic solution containing an oxyanion extractant compound dissolved in an aqueous-insoluble hydrophobic solvent to result in formation of an oxyanion salt of said extractant compound and extraction of said oxyanion salt into said aqueous-insoluble hydrophobic solution, wherein said extraction results in an extraction affinity (D) of said oxyanion of at least 1, wherein D is the concentration ratio of said oxyanion in the organic phase divided by the concentration of said oxyanion in the aqueous phase; wherein said extractant compound has the following composition: wherein at least one of R1-R10 is or contains a hydrocarbon (R) group containing at least 4, 5, 6, 7, 8, 9, 10, 11, or 12 carbon atoms.
    Type: Grant
    Filed: March 29, 2019
    Date of Patent: May 11, 2021
    Assignee: UT-Battelle, LLC
    Inventors: Neil J. Williams, Radu Custelcean, Charles A. Seipp, Bruce A. Moyer, Ross Ellis, Carter W. Abney
