| 摘 要： | 引 言双水相萃取技术是近年来发展很快的一种生物分离方法[1,2 ] .由于系统中分层的两相都是水相 ,所以该系统为物质的分离特别是生物活性物质的分离提供了温和的环境 .在免疫分析、生物转化等方面也具有良好的应用前景[3] .以往对双水相系统的开发利用基本上仅局限于高分子系

| Abstract: | This study was about the cloud point of alkyl polyoxyethylene (AEO 9) and aqueous two phase systems formed by AEO 9 aqueous solution It was shown that the cloud point of AEO 9 aqueous solution was related to the composition and aqueous two phase systems would be formed when the temperature was above the cloud point Salt has an important influence on the properties of AEO 9 solution It could lower the system cloud point and reverse surfactant rich phase and surfactant leau phase of aqueous two phase system.Methylene blue could be extracted to some extent in the aqueous two phase system of AEO 9 If the system contained ionic surfactant, the distribution coefficient ( D ) of methylene blue would be changed Cationic surfactant could make D larger and anionic surfactant could make D smaller The mechanism behind extraction in ATPS was discussed |
