  • Zero-valent metallic treatment system and its application for removal and remediation of polychlorinated biphenyls (PCBs)
    Patent number: 8163972
    Abstract: PCBs are removed from contaminated media using a treatment system including zero-valent metal particles and an organic hydrogen donating solvent. The treatment system may include a weak acid in order to eliminate the need for a coating of catalytic noble metal on the zero-valent metal particles. If catalyzed zero-valent metal particles are used, the treatment system may include an organic hydrogen donating solvent that is a non-water solvent. The treatment system may be provided as a “paste-like” system that is preferably applied to natural media and ex-situ structures to eliminate PCBs.
    Type: Grant
    Filed: May 13, 2009
    Date of Patent: April 24, 2012
    Assignee: The United States of America as represented by the Administrator of the National Aeronautics and Space Administration
