Cu(II)与甘氨酸二元体系配合物的循环伏安行为探讨

The Discussion of the Cyclic Voltmmetry Behavior of the Complexes of Cu and Glycine

对Cu(II)与甘氨酸(Gly)的二元体系配合物进行了循环伏安行为的探讨,讨论了电极反应过程及其配体对中心离子氧化还原电势的影响,采样间隔时间对峰电流和峰电位的影响。实验表明,在KN O3介质中,Cu(II)在铂电极上的电化学反应是半可逆过程,Cu(II)与甘氨酸(G ly)的配合物在铂电极上的电化学反应是不可逆的,随采样间隔时间的增加,峰电位差和峰电流均减小。

The cyclic voltmmetry behavior of complexes of KNO3 and Cu with glycine and their influence were investigated though the experiment. The results show that there is a partial reversible electrochemistry reaction Cu and irreversible electrochemistry reaction on the platinum eletrode for the complexes of Cu and glycine. With the increase of the sampling time,both the peak potential differences and the peak electric current reduce accordingly.
