Desorption kinetics of PCP-contaminated soil: effect of temperature

摘要

A thermally enhanced pump-and-treatment method for pentachlorophenol (PCP)-contaminated soil and ground- water has shown potential advantages over the traditional pump-and-treatment method. Studies on the desorption kinetics of PCP from aquifer soil are the first step toward quantitative assessment of the newly proposed method. Five series of desorption batch tests were conducted at different temperatures, and the test results were analyzed by linear regression to determine the best-fit kinetic model for PCP desorbed from the contaminated field soil under all temperature conditions.
