胆固醇是一种重要的生物物质,在 DMF-NaI-H_2O,体系中借助于电活性媒介体可以使其氧化。使用旋转环-盘电极法、卷积电势扫描伏安法和电势阶跃法等研究了在该体系中胆固醇电化学氧化反应的历程;测定了一些基本参数;表明整个电化学氧化过程具有 EC 催化历程的特性。
Cholesterol is an important biological substance that can be oxidized in DMF-NaI-H 2 O systems by means of electroactive mediators. The progress of electrochemical oxidation of cholesterol in this system was investigated by means of rotating ring-disk electrode method, potentiodynamic voltammetry and potentiometric step method. Some basic parameters were measured. It was shown that the whole electrochemical oxidation process has EC catalysis History of the characteristics.
