Thermal desorption of fluorene, anthracene, pyrene, and benzo(a)pyrene in soil contaminated with PAHs was performed using a rotary desorber at temperatures of 300-500 ℃, and the dependency of the PAH removal efficiency on the percentage water content, residence time, and thermal desorption temperature was investigated. The removal efficiencies were inversely proportional to the boiling points of PAHs, and the removal efficiencies decreased with decreasing residence time and heating temperature. The reaction rate constant and activation energies (EA) were estimated to determine the thermal desorption properties of each substance, and the activation energies were found to be 29.50-34.48 kJ mol^(-1). Freeman-Carroll’s law was applied along with the Arrhenius equation to extract the thermal desorption properties from the data obtained in this experiment.
