阴离子交换膜支撑的两互不相溶界面上电荷转移反应的研究

摘要：本文主要用购自北京的JAM-II膜作为主要的阴离子交换膜进行，并同时用所购买的上海阴离子交换膜和山东阴离子交换膜进行对比实验。通过实验最终确定使用JAM-II膜。同时使用扫描电镜（SEM）对阴离子交换膜进行必要的表征。结果表明所用于试验的阴离子交换膜由于种类、制作工艺的不同，其在扫描电镜下所呈现的表征图也不同。
本次课题中，主要用所购买的离子液体（1-辛基-3-甲基咪唑双三氟甲磺酰亚胺盐）作为主要的油相支持电解质，0.5M的氯化钾溶液作为水相支持电解质，构筑阴离子交换膜支撑的两互不相溶界面。
利用循环伏安法（CV）来研究在该界面上尺寸选择性离子转移反应。结果表明，使用阴离子交换膜所构筑的两互不相溶液液界面可以到到一个较宽的电化学窗口。（-0.5v-1.0v）并利用ClO4-、SO42-、NO2-阴离子来研究在该界面上的尺寸选择性离子转移反应。结果表明，该阴离子在此电化学窗口下发生了离子转移反应，既从水相转移到油相之中。20564

Studies on the Electric charge Transfer Behaviors across the two Immiscible Interface Supported by Anion-Exchange Membrane
Abstract: in this paper, JAM-II membrane from Beijing was used as a main anion-exchange membrane, meanwhile, anion-exchange membranes from Shanghai and Shandong were also applied in this experiment. Through the research，JAM-II membrane was proved to the best one. The scanning electron microscopy (SEM) was used to characterize those above membrane materials, and the results show that different anion-exchange membranes had their own characteristics in SEM because of their different kinds and production process.
   In the work, the commercially available room temperature ionic liquids ( 1-octyl-3- methylimidazolium bis(trifluoromethylsulfonyl)imide ) were used as main supporting electrolyte of oil phase, while potassium chloride solution which the concentration is 0.5M was used as supporting electrolyte of water phase, and then both of the phases were used to build two immiscible interface supported by anion-exchange membrane.
   Using cyclic voltammetry (CV) method to study on size-selective ion transfer behaviors at this interface. And results show when using that two immiscible interface supported by anion-exchange membrane, I can get a better electrochemical window. (-0.5v-1.0v) ClO4-、SO42- 、NO2-anions were used to research the size-selective ion transfer behaviors at this interface. It shows that ion transfer reaction had taken place at this electrochemical window, which means ions had transfer from water phase to oil phase.
