Title:
TECHNIQUE FOR RAPID PREDICTION OF LONG-TERM HYDROPHOBIC ORGANIC CONTAMINANT DESORPTION RATES
Document Type and Number:
WIPO Patent Application WO2002053247
Kind Code:
A3
Abstract:
A laboratory technique for rapidly predicting the long-term hydrophobic organic contaminant (HOC) desorption behaviour 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.
