| 摘 要： | 通过测定 AEO9/己醇 /庚烷 /水 (或盐水 )微乳液体系的相区和电导率 ,研究了盐在非离子型表面活性剂微乳液中的作用。结果表明 :盐能一定程度地促进非离子型表面活性剂微乳液的形成 ,盐离子借助于 AEO9亲水基周围的水分子的作用而渗入界面膜内部 ,促使 W/O型微乳液导电能力增大。微乳液的水相体积分数越大 ,界面膜越疏松 ,盐离子越易渗入界面膜内部 ,导电的活化能越低。

| Abstract: | The effect of salt content on the microemulsion process of alkyl-polyoxyeth- ylene (AEO 9)/hexanol/heptane/H 2O system has been studied by detecting conductivity and microemulsion area in pseudo ternary phase diagram.It is shown that the addition of salt can promote the microemulsion process.The water molecules bonded to the hydrophilic group of AEO 9 would cause the salt ions entering the interface of W/O microemulsion and lead to a increased conductivity of W/O microemulsion.When the water volume fraction in W/O microemulsion is increased, the microemulsion interface would become loose and the salt ions could easily enter the microemulsion interface resulting in a decreased microemulsion activity energy. |
