本文研究了稀土与多卤代变色酸双偶氮胂类试剂的配合反应,测定了配合物的稳定常数、试剂的离解常数和配合物组成,讨论了试剂结构与配合物吸收光谱的关系和β型配合物的生成条件,从而探讨了该类试剂在高酸度下与稀土的配合反应机理.
In this paper, the coordination reaction between rare earth and polyhalogenated chromotropic acid arsines was studied. The stability constants, dissociation constants and complex compositions of the complexes were determined. The relationship between the structure of the complexes and the absorption spectrum of the complexes was discussed. Β Type complex formation conditions, and thus explore the type of reagent in high acidity with rare earth coordination reaction mechanism.
