The Application of Surfactant in Oil-polluted Soil Remediation

Oily-polluted soil has a serious threat to eco environment and human health,so the remediation of oil pollution soil has become an urgent problem to be solved. Because of its amphipathic characteristics,surface active agents were widely used in the remediation of polluted soil by oil. The types and characteristic of surfactant and its repair mechanism in oil-polluted soil remediation were analyzed in this article; studies on the application of surfactant fo oil pollution soil remediation were summarized; the problems and solutions existed in the soil remediation were discussed.
