本文研究了298.2 K下二(2-乙基己基)琥珀酸磺酸钠(气溶胶-OT或AOT)-油水微乳液中过氧二硫酸盐氧化六氰亚铁(II)的反应速率。研究了反应速率常数与表面活性剂浓度、油相性质和摩尔比w=[H2O]/[AOT]的关系。结果表明，当AOT浓度不变时，反应速率随摩尔比w的减小而增大；对于给定的[H2O]/[AOT]值，反应速率与表面活性剂浓度或油相性质无关。
The Oxidation of hexacyanoferrat (II) by peroxodisulfate has been studied in sodium bis(2-ethylhexyl) sulfosuccinate (aerosol-OT or AOT)–oil–water microemulsions at 298.2 K. The rate of this reaction is appreciably higher in a microemulsion than when it takes place in a conventional aqueous solution. The dependence of the rate constants on the surfactant concentration, on the nature of the oil phase and on the molar ratio w=[H2O]/[AOT] has been investigated. Results show that when the AOT concentration remains constant, the reaction rate increases by decreasing the molar ratio, w. For a given [H2O]/[AOT] value, the reaction rate shows no dependence on the surfactant concentration or on the nature of the oil phase.
