摘要
首次用电化学方法在玻碳基体上制成铁氰酸钻修饰膜电极(CHCF/GC).该电极非常稳定,可经受—1.0～0.9V(vs SCE)连续万次以上的电位扫描.讨论了CHCF膜电极的电荷传递过程,研究了影响CHCF膜电极伏安特性的各种因素和对Fe^(3+)/Fe^(2+)电对的催化作用。
The very stable cobalt hexacyanoferrate film electrodes (CHCF/GC) were prepared, which can undergo successively over 10000 cycles of potential sweep between - 1. 0 V and + 0. 9 V(vs SCE). Various factors which affect the voltammetry of CHCF film electrodes and the charge transport process of the electrodes are discussed. The size of the hydrated cations, the concentration of electrolyte and the swelling property of the film in the solvent have significant effects on voltammetry of CHCF film electrodes. Electrocatalysis of CHCF film electrode to Fe3+/Fe2+ is also discussed.
