ApoCopC与Cu(Ⅱ)相互作用的电化学研究
Electrochemical Characteristics on Interaction between ApoCopC and Cu( Ⅱ)
摘要
Abstract
A protein monolayer modified electrode was prepared by the self-assembly of apoCopC at a gold electrode. The interaction of apoCopC with Cu( Ⅱ ) was investigated by cyclic voltammetry at apoCopC-modified gold electrode. The results indicated that the oxidation peak and reduction peak of Cu( Ⅱ ) at apoCopC-modified gold electrode were at 0. 29 V and 0. 09 V, respectively,in which the formal potential was 0.19 V. The peak potentials of Cu( Ⅱ ) at apoCopC-modified electrode were shifted evidently comparing with that at the bare gold electrode. These indicated that apoCopC could adsorb on the electrode firmly and Cu( Ⅱ ) bound to apoCopC to form a complex. Moreover,the effects of scan rate,different concentration on the voltammetric behavior of Cu(H) on the apoCopC/Au electrode were studied, and the electron transfer coefficient(a) was 0. 5, electron transfer rate constant (ks) was 0.75 s-1.关键词
