用现场偏转法结合循环伏安法研究了普鲁士蓝（ＰＢ）及六氰亚铁铟（ＩｎＨＣＦ）膜的电化学氧化还原过程。证实了ＰＢ膜的离子交换的机理为：且酸性条件下还原ＰＢ膜是Ｈ~＋先于Ｋ~＋进入膜内。还原态的ＩｎＨＣＦ膜氧化时，溶液中的阴阳离子同时参与了该反应，但随着阴离子的增大，Ｋ~＋成为该反应的主要参与者。
The electrochemical redox process of Prussian blue (PB) and hexahydronaphty indium (InHCF) films was investigated by field deflection method and cyclic voltammetry. The mechanism of ion exchange of PB membrane was confirmed as follows: the reduction of PB membrane under acidic condition was H ~ + prior to K ~ + entering the membrane. When the reduced InHCF membrane oxidized, the anions and cations in the solution were involved in the reaction at the same time. However, with the increase of anions, K ~ + became the main participant in this reaction.
