摘要
在CTAB／正丁醇／苯的质量比1:1:2和温度30℃下,分别以水和0．1 mol·dm-3KCl溶液、HCl溶液、NaOH溶液作为分散相配制微乳液并测定电导率． CTAB／正丁醇／苯／水微乳区的水含量为0．04-0．53,电导率在0．04-0．20之间不断 升高,在0．20-0．40之间基本不变,在0．40-0．53之间也不断升高．以KCl溶液、 HCl溶液、NaOH溶液作为分散相的微乳液的微乳区大幅度减小,电导率则与纯水微 乳液在相应区域上基本相同．
Microemulsions are compounded separately by H2O and 0. 1 mol ·dm^-3 KC1,HC1,NaOH as dispersing phase at mass ratio 1：1：2 of CTAB/1 - butanol/benzene and 30 ℃. The conductivity of microemulsion with different content of dispersing phase is measured. Water content of CTAB/1 - butanol/benzene/water microemulsion is 0.04 - 0.53. And the conductivity continuously increases in 0. 04- 0. 20, retains constant in 0. 20 -0.40, continuously increases in 0. 40 -0.53 too. Microemulsion region of microemulsion with 0. 1 mol· dm^-3 KCI,HCI,NaOH as dispersing phase are more smaller than microemulsion with water, and conductivity is similar in corresponding region.
