摘 要: 利用溶液的稀译度与其吸光反的关系,导出一个适用测定β-型配合物组成及稳定常数的方法。根据实验数据,用图解法求出稀土β-型配合物的实际组成为3:3.同时给出了其表观稳定常数,讨论了β-型配合物与稀土离子半径、电子结构和公型配合物稳定性的关系。 his paper attempts to carry out investigation on the actual combining ratio and apparentstability constants of β-type homonuclear complexes which lanthanides incorporate with p-hip-purochlorophosphonazo. The method based on the effect of dilution on the degree of dissociation has beenapplied. The actual combining ratio of chelates is determined to be 3:3 by a graphical method as pro-posed in the paper. Meanwhile, the apparent stability constants of them are calculated meticulously.
