摘要
在前人研究的基础上,用混合溶剂对提示的配合物在可见光区测定了它的稳定常数和摩尔吸光系数,计算了溶液中各级配合物的百分组成与配位体浓度的关系,同时考虑了百分组成的变化对摩尔吸光系数的影响及显色反应的关系,并表明混合溶剂可能不参与配合物中.
On the basis of predecessors' study, we have studied the stability
constant and Molar absorptivities of the complex adapting in the mixeci
solvent. Then the percentage composition of the complex relationship with a
concentration of the ligand has been calculated while we have taken into
consideration the percentage composition with Molar extinction and the colour
reaction. And it is shown that the mixed solvent would not possibly participate in the complex.
