| 摘 要： | 报道了葡萄糖氧化酶(GOD)在电化学预处理的玻碳(GC)电极上的电化学行为。GC电极经过高电位阳极氧化,随后反复循环扫描的预处理,可使GOD的吸附能力大为提高,吸附GOD与该电极的直接电子传递近乎可逆。讨论了电化学预处理增强GOD吸附及直接电子传递的可能因素。

| Abstract: | The direct electron transfer between adsorbed glucose oxidase (GOD) and electro chemically pretreated glassy carbon (GC) electrode was studied by cyclic voltammetry. The pretreat ment of GC electrode, which included anodization at +1. 8 V (vs. SCE) for 5 min and cycling thereafter between +0. 4 V and - 0. 8 V at 0. 1 V/s untill a steady voltammogram was obtained, greatly enhanced its ability to adsorb GOD. The direct electron transfer between adsorbed GOD and the GC electrode was quasi-reversible. The enhancement of the adsorption and the direct electron transfer by electrochemical pretreatment was discussed. |
