【摘要】 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。更多还原

【Abstract】 Probe beam deflection(PBD) technique together with electrochemical techniques such as cyclic voltammetry was used to study the ion exchange in prussian blue(PB) film and its analogue indium hexacyanoferrate(InHCF) chemically modified electrodes.The ion exchange mechanism of PB was verified as following:where on reduction in contact with an acidic KCl electrolyte,H￣+enter PB film before K￣+.Both the cations and anions participate concurrently in the redox process of InHCF,meanwhile K￣+ion plays a majr role in the whole charge transfer process of this film with increasing radii of anions.更多还原
