建立了一种电解池置于光谱仪器之外的流通池光谱电化学法。对实验装置的结构和实验方法作了说明。用该法研究了Fe(CN)_6~(3-)/Fe(CN)_6~(4-)和邻联甲苯胺体系,测定了式量电位E°和电子转移数n,结果与文献值一致;还测定了Fe(CN)_6~(3-)/Fe(CN))6~(4-)体系的热力学常数ΔS°和ΔH°。
A flow cell spectroscopic electrochemical cell with an electrolysis cell placed outside the spectrometer was established. The experimental device structure and experimental methods are described. The Fe (CN) _6 ~ (3 -) / Fe (CN) _6 ~ (4-) and o-tolidine systems were studied by this method. The results showed that the values of E (subscript E) and electron transfer number The thermodynamic constants ΔS ° and ΔH ° of Fe (CN) 6 ~ (3 -) / Fe (CN) 6 ~ (4-) system were also determined.
