摘　　要：淋洗剂是污染土壤化学淋洗修复技术的关键。微乳液淋洗剂因具有较少的地层吸附量、较低的表面和界面张力、较高的低渗透土壤穿透能力以及对污染物的良好溶解性能等特点,受到广泛关注。综述了微乳液淋洗剂在去除土壤中有机污染物的研究进展,并详细讨论了表面活性剂的特性对微乳液的性能影响,从生物降解性和生物毒性等方面探讨了微乳液型淋洗剂的应用前景。Leaching agent is the key of chemical leaching remediation technology of contaminated soil.Microemulsion leaching agent has been widely concerned because of its low formation adsorption capacity,low surface and interfacial tension,high penetration ability of low permeability soil and good solubility of pollutants.The research progress of microemulsion leaching agent in removing organic pollutants from soil was reviewed,and the effects of surfactants on the properties of microemulsion leaching agent were discussed in detail.The application prospect of microemulsion leaching agent was discussed from the aspects of biodegradability and biotoxicity.
