Technique for rapid prediction of long-term hydrophobic organic contaminant desorption rates

摘要

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.
