The use of a combined process of surfactant-aided soil washing and coagulation for PAH-contaminated soils treatment

López-Vizcaíno López, Rubén; Saez, C.; Cañizares Cañizares, Pablo; Rodrigo Rodrigo, Manuel Andrés (Elsevier, 2012-03)

Polycyclic aromatic hydrocarbons (PAHs) persist in soils due to their low volatility, low water solubility and low biodegradability, all of which make it difficult to remove this type of compound from soils. The work ...
