Kinetics of Crude Oil Desorption from Contaminated Soil

The objective of this work was to study the power of surfactant solutions on the remediation of soils contaminated by crude oil during a batch washing process. We used as surfactants Sodium dodecyl sulfate (SDS), Sodium dodecyl benzenesulfonate (SDBS). In this study, we examined the effect of various parameters (level of contamination, type of surfactant and contamination age) on the surfactant elimination of oil from soil. The results obtained in this study showed the potential of surfactants in the cleanup of soils contaminated by hydrocarbons, and that the surfactants structure has a crucial impact on the elimination kinetic.
