  • Treatment of environmental contaminants
    Publication number: 20070189855
    Abstract: Contaminants, such as volatile organic compounds, are removed from an environmental medium, such as contaminated soil, rock, groundwater, waste water and the like, by treatment with a combination of a persulfate, such as a sodium persulfate, and hydrogen peroxide.
    Type: Application
    Filed: July 28, 2004
    Publication date: August 16, 2007
