分别在不同盐浓度的自由水和不同液滴尺寸的微乳液中测量了过硫酸钾氧化碘离子的化学反应速率常数 ,获得微乳液水核中水的活度 ,探讨了水的活度及体系中离子强度与反应速率的关系 ,发现当表面活性剂与水的摩尔比R≤ 2 0时 ,水的活度随微反应器尺寸减小而快速下降
The chemical reaction rate constants of potassium iodate in potassium persulfate were measured in different concentrations of free water and microemulsions with different droplet sizes respectively to obtain the activity of water in microemulsion water core and the activity and system of water The relationship between the ionic strength and the reaction rate showed that when the molar ratio of surfactant to water R ≤ 20, the activity of water decreased rapidly with the decrease of the size of the microreactor
