  • Sulfidated nanoscale zerovalent iron and method of use thereof
    Patent number: 11111164
    Abstract: The present disclosure relates to sulfur-containing zerovalent iron nanoparticles and the use of same for transforming chlorinated solvent pollutants and which may therefore be useful as water treatment technology for restoration of groundwater resources contaminated with toxic, chlorinated solvent pollutants.
    Type: Grant
    Filed: July 26, 2019
    Date of Patent: September 7, 2021
    Assignee: THE ROYAL INSTITUTION FOR THE ADVANCEMENT OF LEARNING/MCGILL UNIVERSITY
    Inventors: Sourjya Bhattacharjee, Subhasis Ghoshal
  • SULFIDATED NANOSCALE ZEROVALENT IRON AND METHOD OF USE THEREOF
    Publication number: 20200031695
    Abstract: The present disclosure relates to sulfur-containing zerovalent iron nanoparticles and the use of same for transforming chlorinated solvent pollutants and which may therefore be useful as water treatment technology for restoration of groundwater resources contaminated with toxic, chlorinated solvent pollutants.
    Type: Application
    Filed: July 26, 2019

  • RHAMNOLIPID COATED NANOSCALE ZEROVALENT IRON EMULSIONS AND METHOD OF USE THEREOF
    Publication number: 20190118017
    Abstract: The present disclosure relates to use of rhamnolipid coated nanoparticles of zero valent iron (NZVI), either in its bare form or functionalized with other materials (M) such as trace amounts of a palladium catalyst, for transforming chlorinated solvent pollutants by targeting the non-aqueous phase, which contains said chlorinated solvent pollutants. The method may be useful as water treatment technology for restoration of groundwater resources contaminated with toxic, chlorinated solvent pollutants as well as in the treatment of industrial waste of chlorinated solvents in reactor systems.
