Remediation of Contaminated Soils by Surfactant-Aided Soil Washing

Abstract

This paper provides reviews and updates of surfactant-aided subsurface remediation. Experimental measurements were made of various systems comprising two non-ionic surfactants, five soils of different fractional organic carbon contents, and several typical hydrophobic organic compounds (HOCs). Soil-washing performance was quantified using reciprocal surfactant-soil solubilization coefficients
