摘要： 混合配体络合物是络合物溶液化学研究中一个十分活跃的领域,有关镉的混合配体有色络合物见诸文献者不多[1]。作者曾以光度法研究了镉(Ⅱ)-邻二氮菲(phen)-溴苯三酚红(BPR)三元体系中形成络合物的组成及有关光学特性[2]。

Abstract: The equilibrium constant of mixed-ligand complex formation in the following reaction  has been evaluated by a new variant of graphical method based on the data of spectrophotometric measurements. The equilibrium constant and the apparent stability constant of the mixed-ligand complex are 6.7×1010 and 2.6×1022 respectively at 25℃, pH8 and ionic strength 0.1.
