电化学方法研究KOH溶液中高铁酸根的性质

摘要在铂微盘电极上利用电位阶跃和循环伏安技术,求出了高铁酸根离子在不同温度、不同浓度的KOH溶液中的扩散系数。探讨了高铁酸根离子在KOH溶液中扩散传质过程的特点对超铁电池放电性能所造成的影响。另外,循环伏安试验发现高铁酸根离子在KOH溶液中的电化学还原是一个多步过程。

Abstract： Techniques of chronoamperometry and cyclic voltammetry were employed to study the electro-reduction and diffusion behavior of ferrate(Ⅵ) ion in different concentration of KOH solution at different temperature.Diffusion coefficient of ferrate(Ⅵ) ion could be calculated.The impact of the mass transfer of ferrate(Ⅵ) ion in electrolyte on the super-iron battery in discharge has also been discussed.In addition,the experimental results of cyclic voltammetry indicated that the electro-reduction of ferrate(Ⅵ) ion involves more than one step.
