摘要
利用紫外光谱法和循环伏安法研究几种Ce^(4+)离子氨基酸配合物。结果表明几种氨基酸均能在pH为6的弱酸性条件下与Ce^(4+)形成配合物,不同的配体与Ce^(4+)形成的配合物的还原电位均比Ce^(4+)的更负。配体与Ce^(4+)的配比不同,形成配合物循环伏安曲线和紫外光谱有差异。
Ultraviolet-visible spectrophotometry (UV) and cyclic voltammetry (CV) were used to study cerium (IV) and the complexes of several kinds of amino acids. The results demonstrate that complexes formed under the condition of pH = 6 and their reduction potentials became more negative than that of Ce4+. The different ratio of Ce4+ with the ligands will form different cyclic voltammograms and ultraviolet spectrums.
