The mobilization and biodegradation of phenanthrene in soil was enhanced by using paraffin oil, which was stabilized by the addition of a surfactant (Brij 30). The ratio of paraffin oil/Brij 30 was determined by measuring the change in the critical micelle concentration. When only surfactant was used, the stabilized paraffin oil emulsion could dissolve more phenanthrene in the water phase. Column experiment showed increased phenanthrene mobilization from the contaminated soil. The phenanthrene mobilized in the paraffin oil/Brij 30 emulsion was biodegraded faster than that in water phase or surfactant solution. This result indicates that a paraffin oil/surfactant system can be effectively used for the removal of PAH from contaminated soil.
