  • Technique for rapid prediction of long-term hydrophobic organic contaminant desorption rates
    Patent number: 6546341
    Abstract: A laboratory technique for rapidly predicting the long-term hydrophobic organic contaminant (HOC) desorption behavior in a contaminated soil or sediment useful for planning remediation schemes and/or assessing alternative remediation endpoint decisions employs a superheated water extraction technique for rapid prediction of long-term HOC desorption. The proposed method has great practical significance because desorption at ambient temperatures requires months or years, while high temperature experiments are accomplished in hours or days.

  • Method and apparatus for solar destruction of toxic and hazardous materials
    Patent number: 4432344
    Abstract: Toxic and hazardous organic materials are photochemically and thermally changed into innocuous and environmentally acceptable products through the proper application of solar energy. The present invention is especially well-suited for the destruction of polychlorinated biphenyls (PCB's) which are resistant to conventional incineration The method and apparatus described herein are also capable of handling liquids, solids or vapors, with only minor operating modifications.
