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 voltammetry of binary complexes of Cu (II) and glycine (Gly) was discussed. The influence of electrode reaction process and ligand on the redox potential of the central ion was discussed. The effects of sampling interval on the peak current and The effect of the peak potential. The experimental results show that the electrochemical reaction of Cu (II) on the platinum electrode is semi-reversible in KN O3 medium and the electrochemical reaction of Cu (II) and glycine on the platinum electrode is irreversible With the increase of sampling interval, the peak potential difference and peak current decrease.
