摘要: 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。

Abstract: The electroreduction of low concentration iodate in H_2SO_4 was studied on the platinum electrode. The intermediate I_2 and the final product I~-, which are form- ed during the electroreduction of iodate, are detected by using the rotating ring-disk electrode. The kinetic parameters were measured. The mechanism of eletroreduction of iodate are proposed here.
