| 摘 要： | 综述了用微乳液法萃取分离水中的非离子有机污染物、重金属离子和在湿法冶金工业中萃取分离金属离子的研究进展。表面活性剂、助表面活性剂、油和水形成WinsorⅡ或WinsorⅢ型微乳液,非离子有机污染物和金属离子进入微乳液的双连续区域或者是W/O型的微乳液中,从而实现水和有机物或金属离子的分离。对影响微乳液萃取的因素如助表面活性剂、助表面活性剂与表面活性剂的比率(nC/nS)和盐度等进行了论述。

| Abstract: | The application of microemulsions in solvent extraction has been reviewed.The removal of nonionic organic pollutants,heavy metals in polluted water of chemical engineering by extraction through microemulsions was discussed in this paper.Nonionic organic pollutants and metal ions in polluted water can be extracted into the region of bicontinuous structure or Winsor II microemulsion formed by surfactant/cosurfactant/ oil /water system,and then the separation of water from nonionic organic pollutants and metal ions was obtained. Influencing factors on the utilization of microemulsions in above fields were also explicated. |

| Keywords: | microemulsion solvent extraction surfactant nonionic organic pollutants metal ion |
