Abstract
In this study, electrokinetic remediation tests were performed with spiked fine-grained soil by phenanthrene which is representative hydrophobic organic contaminant of petroleum hydrocarbon. And also, the enhanced method was used with surfactant concentration variation and elapsed time to achieve more higher removal efficiency than conventional electrokinetic treatment. In conventional electrokinetic treatment, most phenanthrene was not transported. But, in the enhanced method used by the surfactant, phenanthrene moved form anode to cathode region and accumulated in cathode region. Also, the transportation rate of phenanthrene was increased with surfactant concentration increasement and elapsed time.
