Vacuum-Enhanced Far-Infrared Thermal Desorption of Clay Soil Polluted by R-Hexachlorocyclohexane

Abstract:

A full-field investigation was conducted of vacuum-enhanced far-infrared thermal desorption of clay soil polluted by r-Hexachlorocyclohexane (RH). It demonstrated that vacuum-enhanced far-infrared thermal desorption process is effective for remediating RH contaminated clay soil. The thermal desorption rate (C_E) were improved under such conditions: thermal desorption time 20 minutes, thermal desorption temperature 200 °C, vacuum 0.05MPa and water content 15%. The mass balance of RH was verified after 20min of reaction. The residue RH was distributed in the condensate, whereas the soil and active carbon contained lower amounts of RH.
