Desorption kinetics of selected volatile organic compounds from field contaminated soils
Batch experiments conducted with five, low organic carbon content (0.04-1.12%), field contaminated soils (three silty-clay and two sandy soils) for the simultaneous desorption of trichloroethylene, tetrachloroethylene, toluene, and xylene showed that a substantial portion (48-94%) of the sorbed contaminant mass resisted desorption in deionized water-soil mixtures after 7 days of contact time. The desorption pattern was biphasic, a slow desorption following an initial fast phase
