摘要
利用电化学石英晶体微天平（EQCM）手段，结合循环伏安法．计时电流法对六氰亚铁铜（CuHCF)膜修饰电极及其在不同水溶液中的离子交换机制进行了研究。结果表明；通过循环伏安法，在Pt电极上可以牢固地形成CuHCF膜．在氧化还原过程中，不仅是阳离子，阴离子也参与了在CuHCF膜中的传输。
The ion exchange mechanism accompanying the redox process on cupric hexa- cyanoferrate (CuHCF) modified electrode has been studied by electrochemical quartz crystal microbalance technique in various aqueous solutions. Results demonstrate that the charge neutrality of the film in redox process is attained predominately by the transport of cation, but anion also participates in this transport.
