摘要：

研究了两种不同类型的微乳液萃取镓的热力学。微乳液的组成分别为十六烷基三甲基溴化铵／正丁醇／正庚烷／HCl(溶液)和油酸钠／正戊醇／正庚烷／HCl(溶液)。对比两种不同表面活性剂组成的微乳液,分别考察了萃取时间、水油比、盐酸浓度和萃取剂含量等因素对萃取的影响,确定了最佳工艺条件,同时探讨了表面活性剂的性质对萃取的影响。结果表明,微乳液萃取镓的速率快,萃取率高达98％,而不同种类表面活性剂会对萃取产生很大影响;该微乳液被证明是一种非常优秀的萃取介质。

Abstract:

The thermodynamics of the gallium extraction by two different kinds of microemulsions were studied. The microemulsion, which contained cationic surfactant or anionic surfactant, was composed of cetyltrimethylammonium bromide (CTAB)／n-butanol／n-heptane／HCl(solution) or sodium oleate (NaOL)／npentanol／n-heptane／HCl(solution). The variables such as the equilibrium time, the volume ratio between two phases, HCl′s molarity and the extractant concentration were tested, and the optimized conditions of extraction were fixed. The effects of different nature of the surfactants on the extraction were also discussed. The results showed that, in pretty short time, the extraction ratio by the microemulsion systems could achieve 98％. Microemulsion was proved to be an outstanding extraction medium.
