ＳＯＤ在薄层电池金微网栅电极上的电化学行为①吴霞琴＊刘倩许兵孟晓云章宗穰（上海师范大学化学系电化学研究室上海２００２３４）超氧化物歧化酶（Ｓｕｐｅｒｏｘｉｄｅｄｉｓｍｕｔａｓｅ，简称ＳＯＤ）能专一消除生物氧化产物超氧阴离子（Ｏ－２），因而在抵御疾病，...
The electrochemical behavior of superoxide dismutase (Cu, Zn SOD) was investigated on gold wire electrode and gold minigrid with thin layer cell by cyclic voltammetry. A quasi reversible redox wave of SOD has obtained on gold minigrid thin layer electrode, but only oxidation peak has observed on gold wire electrode. The electrochemical reaction parameters, such as the formal potential E 0 ′, diffusion coefficient D and standard rate constant k 0′ were estimated.
