本文采pH电位滴定法和电子光谱法进行了肾上腺素与f区元素[Nd~(3+)、Gd~(3+)和Tm~(3+)]溶液的反应机理、配合物组成、配位原子位置、配位键性质和配合物稳定性等方面的研究。肾上腺素对Nd~(3+)和Tm~(3+)的f-f电子跃迁产生了微扰作用,致使其配合物的吸收谱线红移。在350～650nm区间内,三种f区离子形成的配合物的吸收光谱随pH值的提高而发生紫移现象。 In this paper, the reaction mechanism between epinephrine and f-element [Nd 3+, Gd 3+ and Tm 3+] solutions was investigated by pH potentiometric titration and electron spectroscopy. The complex composition, Bit atom position, coordination bond properties and stability of complexes. Epinephrine has perturbed the f-f electron transition of Nd ~ (3+) and Tm ~ (3+), resulting in a red shift of the absorption spectrum of the complexes. In the range of 350-650 nm, the absorption spectra of the complexes formed by the three kinds of f ions evolve with the increase of pH value.
