【摘要】 本文研究了Fe(Ⅲ)、Zn(Ⅱ)、Ag(Ⅰ)的邻菲罗啉配离子与四苯硼酸根生成三元离子缔合配合物沉淀的pH条件,实验验证了金属—邻菲罗啉配离子与四苯硼酸根的缔合比。用系数比率法测定了Fe(Ⅲ)、Fe(Ⅱ)、Co(Ⅱ)、Ni(Ⅱ)、Cu(Ⅱ)、Zn(Ⅱ)、Cd(Ⅱ)、Ag(Ⅰ)的邻菲罗啉—四苯硼酸根三元配合物沉淀的溶度积Ksp,并对有关缔合性质进行了探讨。更多还原

【Abstract】 The pH conditions for forming ternary ion-associating complexes of Fe (Ⅲ) , Zn (Ⅱ) ,Ag (Ⅰ) with 1,10-phenanthroline and tetraphenylborate anion were studied and the complexing ratios of them were proved by experiments. The solubility products of ternary ion-associating complexes of Fe (Ⅲ) ,Fe (Ⅱ) ,Co (Ⅱ) ,Ni (Ⅱ) ,Cu (Ⅱ) , Zn (Ⅱ ) , Cd ( Ⅰ ) and Ag ( Ⅰ ) with 1, 10-phenanthroline and tetraphenylborate anion were determined. And the associating curves, as well as the precipitating ability of complex ion with tetraphenylborate anion, were also discussed.更多还原
