摘要
综述了在超临界二氧化碳 (SFC)中 ,能形成微乳液的表面活性剂 (SAA)的结构特性 ,助SAA对SFC微乳液形成的影响以及SFC微乳液的研究现状。同时 ,介绍了紫外 -可见吸收光谱、傅立叶 -红外光谱、小角中子散射和小角X光散射等近代测试方法 ,及其在SFC微乳液形成及其结构特性研究中的应用。另对SFC微乳液在化学反应、生物活性物质及金属离子萃取。
The structure properties of surfactants,which can form supercritical carbon dioxide microemulsions and the effect of cosurfactant on the formation of supercritical carbon dioxide microemulsion are reviewed.Meanwhile,the application of current method of determination such as ultraviovisiblc absorbancc spcctroscopy,fouricr-transform infrarcd spcctroscopy,small-anglc ncutron scattcring and smallangle x-ray scattering to the study of formation and structure properties of supercritical carbon dioxide microemulsion are introduced.Moreover,the application of supercritical carbon dioxide microemulsions to the field of chemical reaction,extraction of biochemicals and metal ions,synthesis of materials and cleaning are also introduccd.
