摘要：

A desorption and desorption of polynuclear aromatic hydrocarbons from soil in the presence of Supercritical CO2 is studied. The soil adsorption isotherms are described by the Freundlich and BET models. Polar modifiers like methanol and water are found to exhibit a strong desorptive influence. A simple, single-parameter model using linear desorption kinetics is used to fit the desorption data.
