Desorption kinetics studies on PAH-contaminated soil under varying temperatures
The purpose of this study was to investigate the effect of temperature on the release of polycyclic aromatic hydrocarbons (PAHs) from aged contaminated soil. The release of fluorene, phenanthrene, anthracene, fluoranthene and pyrene at 7, 15, 18 and 23 °C was studied using a column leaching method with a hydraulic retention time of 0.5 h. As the temperature declined from 23 to 7 °C the concentrati
