In situ Soil Decontamination by Radio-Frequency Heating-Field Test.

摘要

This report summarizes a successful pilot test of radiofrequency soil decontamination performed at an abandoned fire training area on Volk Field ANGB WI. The results of preliminary laboratory column studies are provided as well as complete discussion of soil sampling and analytical methods. Approximately 500 cubic feet of soil was heated to a temperature of 150 C using radiofrequency energy. During the 12 days of heating, the hot vapors were collected from the soil surface and concentrated using a condenser and activated carbon. Final soil sampling showed excellent removal rates of fuel contaminants. Over 99 percent of the aromatic compounds, such as benzene, were removed from the soils. Less volatile aliphatics were reduced by over 95 percent. Provides a complete summary of operating conditions and soil decontamination results.
