摘要
用循环伏安法首次在金电极上制成一种新的类普鲁士-亚换氰化锌膜.研究发现,膜的形成不仅与新生成的Fe(CN)4-6和Zn(Ⅱ)有关,同时也受溶液中共存的其它离子的品种和浓度的影响.膜氧化时解离,溶解;还原时受膜厚度不同的影响呈不同的电极反应过程.现已提出了可能的反应机理.并利用亚铁氰化锌膜的特别性质,分析测定Zn(Ⅱ)达1×10-7mol/L,并也定量测定了K+.
A new type of Prussian blue analog Zinc hexacynoferrate(ZnHCF)film modified gold electrode is described. Its electrochemical behavior is influenced not only by fresh Fe(CN) 4- 6 and Zn 2+ but also the kind and concentration of other electrolyte ions presented in the solution. The possilbe electrochemical reaction of the ZnHCF film has been discussed. This film is used to determine Zn 2+ and K + quantitatively. \ \
