本文对碘化钠-碘浓溶液体系中碘离子阳极氧化扩散电流的性质进行了研究.指出在这种体系中,阳极扩散电流不由碘离子向阳极的扩散速度所控制,而是由阳极电解产物碘由电极表面向溶液中的扩散所控制;其极限扩散电流密度与本文中定义的碘的未饱和度△m_(I_2),max成正比,后者是一个与通常所指的碘的不饱和度在意义和数值上都不相同的物理量.
In this paper, the properties of iodide anodic oxidation diffusion current in sodium iodide-iodine concentrated solution system are studied. It is pointed out that in this system, the anode diffusion current is not governed by the diffusion rate of iodide ions to the anode, but rather the anode electrolysis product Iodine is controlled by the diffusion of the electrode surface into the solution; its limiting diffusion current density is proportional to the degree of unsaturation of iodine, Δm_ (I_2), max, as defined herein, which is a function of the iodine unsaturation normally referred to Degree of physical significance in terms of both physical and numerical.
