Removal of PAHs with surfactant-enhanced soil washing ...

Among them, surfactant-enhanced soil washing has been suggested a promising technique since it has relative high removal ratio while is cost-effective (e.g., Paria, 2008, Laha et al., 2009). Surfactants enhance the solubility of hydrophobic organic compounds by partitioning them into the hydrophobic cores of surfactant micelles ( Abriola et al., 1993 , Brown et al., 1994 , Goudar et al., 1999 ).
