制作了一种以网状玻璃碳为工作电极的光谱电化学池,并介绍了对网状玻璃碳电极的处理方法。选用铁氰化钾-亚铁氰化钾体系,对其式量电位(E°′)、反应电子数(n)和扩散系数(D_R)进行了测定,取得较为满意的结果。
A spectroscopic electrochemical cell with a mesh glassy carbon as the working electrode was fabricated, and the treatment of the reticulated glassy carbon electrode was introduced. The potassium ferricyanide - potassium ferrocyanide system was used to determine the type potential (E ° ’), the number of reaction electrons (n) and the diffusion coefficient (D_R). The satisfactory results were obtained.
