通过对金属离子Mn(Ⅱ)与L-谷氨酸(Glu)二元体系形成配合物的循环伏安行为的研究,探讨摩尔配比、pH值、扫描速率、支持电解质、电极各种因素对峰电流的影响,试图运用循环伏安法探究配合物扫描的最佳条件.实验结果表明:当Mn(Ⅱ)与Glu的摩尔配比为1:2、pH=3.33、扫描速率v=26 mV/s、KNO3为支持电解质,铂电极上Mn(Ⅱ)与Glu配合物电极反应的峰电流之比(Ipa/Ipc)最大,此为最佳实验条件.
By studying the cyclic voltammetric behavior of the complexes formed by the binary system of metal ions Mn (Ⅱ) and L-glutamic acid (Glu), the effects of various factors such as molar ratio, pH, scan rate, supporting electrolyte and electrodes The results showed that when the molar ratio of Mn (Ⅱ) to Glu was 1: 2, pH = 3.33, the scan rate was v = 26 mV / s, KNO3 is the supporting electrolyte, and the ratio of peak current (Ipa / Ipc) of Mn (Ⅱ) and Glu complex electrode at platinum electrode is the best, which is the best experimental condition.
