本文应用循环伏安电化学测量技术研究了铕(Ⅲ)、铈(Ⅲ)稀土离子、稀土与2,4,5—三氯苯氧乙酸、α—荼乙酸、荼氧乙酸、2,4—二氯苯氧乙酸等植物生长素的混合物以及生长素类稀土配合物在玻碳电极上的电化学行为。实验结果表明:生长素类配体为非电极活性物质,铕(Ⅲ)及其与生长素类混合物都显示了近乎可逆的电子迁移过程;铈(Ⅲ)及其与生长索类的混合物则为不可逆的电极过程,而生长素类稀土配合物依配体的不同而显示电活性或非活性。 In this paper, cyclic voltammetry electrochemical measurements were used to study the effect of rare earth ions such as europium (Ⅲ), cerium (Ⅲ), rare earth, 2,4,5-trichlorophenoxyacetic acid, α-tocopheryl acetate, Dichlorophenoxyacetic acid and other auxin mixtures and auxin rare earth complexes at the glassy carbon electrode electrochemical behavior. The experimental results show that the auxin ligands are non-electrode active materials, and europium (Ⅲ) and its mixtures with auxins show near reversible electron transport. The mixture of cerium (Ⅲ) Irreversible electrode processes, whereas auxin-based rare earth complexes show electroactive or non-viable activity depending on the ligand.
