依来铬红B的电还原
摘要:
本文用普通极谱、脉冲极谱、循环伏安法研究了依来铬红B的电还原。随着pH不同,共可产生3个波(pH6.2-12.2)。总波高相当于-受扩散控制的不可逆2电子还原波;第一波和第三波分别为吸附前波和吸附后波。根据实验结果,提出-电还原机理。

ELECTROREDUCTION OF ERIOCHROME RED B
Abstract:
Electroreduction of eriochrome red B was studied by d.c.polarography,differential pulse polarography, and cyclic voltammetry. There appeared three waves(peaks) over pH range of 6.2-12.2. The sum of wave Ⅰ,Ⅱ and Ⅲ is of diffusion controlled, two-electron,and irreversible one.Wave Ⅰ and Ⅲ are of adsorption prewave and post-wave,respectively,From experimen-tal results a mechanism for electroreduction of eriochrome red B was pro-posed.
