BONIFICA DI SUOLI UMIDI INQUINANTI

摘要

The present invention relates to a process for treatment of soils polluted by high-boiling organic substances, such as petroleum, polynuclear aromatics and chloro-organic substances, which process uses an extractant with high dissolving power for the pollutant, and which improves the soil-extractant contact thanks to the addition of a minimal amount of a hydrophilic co-solvent.
