本文研究了低浓度的碘酸盐在硫酸介质中,在铂电报上的电化学还原。用旋转盘环电极检测到了碘酸盐阴极还原的中间产物I_2及最终产物I~-。测定了电化学反应的动力学参数。最后提出了磺酸盐阴极反应的机理。
In this paper, the electrochemical reduction of platinum ions in low concentration of iodate in sulfuric acid medium was studied. Iodide cathode reduced intermediate product I_2 and final product I ~ - were detected by the rotating plate ring electrode. The kinetic parameters of the electrochemical reaction were determined. Finally, the mechanism of sulfonate cathode reaction is proposed.
