本文用循环伏安法研究了苄基紫精(BV~(2+))在玻碳(GC)电极上的电化学行为。BV~(2+)在未活化的GC电极上的电极过程强烈地依赖于BV~(2+)浓度、扫描速度和电位范围。BV~(2+)在活化的GC电极上的吸附能力大为增强,当其浓度低时只表现出吸附BV~(2+)的电极过程,在高浓度下吸附BV~(2+)与溶液中的BV~(2+)同时参与电极过程。讨论了GC电极活化的可能影响。
In this paper, the electrochemical behavior of benzyl viologen (BV ~ (2+)) on glassy carbon (GC) electrode was studied by cyclic voltammetry. The electrode process of BV ~ (2+) on unactivated GC electrode strongly depends on the concentration of BV ~ (2+), the scan speed and the potential range. The adsorption capacity of BV ~ (2+) on activated GC electrode is greatly enhanced. When the concentration of BV ~ (2+) is low, only the process of adsorption of BV ~ (2+) BV ~ (2+) in solution also participates in the electrode process. The possible effects of GC electrode activation are discussed.
