| 摘 要： | 研究了十四烷基三甲基氯化铵(TTAC)与十二烷基苯磺酸钠(SDBS)混合表面活性剂水溶液双水相体系的分相情况、萃取性能及两相的微观结构.结果表明,TTAC/SDBS混合表面活性剂水溶液在30℃下能够形成稳定的双水相体系;该双水相体系对亚甲基蓝、靛红都具有一定的萃取分离作用.其上、下两相的微观结构明显不同,这是其能够形成稳定双水相体系且具有萃取作用的重要原因.

| Abstract: | The phase region, extraction performance and microstructure of two-phase aqueous system of mixtures of sodium dodecyl benzene sulfonate （SDBS） and tetradecyl trimethyl ammonium chloride （TTAC） were researched. Results show that the mixed aqueous solution of SDBA and TTAC forms stable two-phase regions at 30℃. Resultant two-phase aqueous system can extract and separate methylene blue and isatin at 30 ℃ to a certain degree. This is because the upper and lower phases of the two-phase aqueous system have much different microstructure, allowing the formation of stable two-phase aqueous system with a certain degree of extraction and separation performance. |
