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。 Several Ce ~ (4 +) ion amino acid complexes were studied by UV spectroscopy and cyclic voltammetry. The results showed that several amino acids were able to form complexes with Ce ~ (4+) at pH 6, and the reduction potentials of different ligands and Ce ~ (4+) 4+) is more negative. The ligand and Ce ~ (4 +) ratio is different, the formation of complex cyclic voltammetry and UV spectra are different.
