摘要
合成 6个硒功能化杯芳烃为载体 ,采用双层夹心膜电位法直接测定了溶剂聚合物膜中载体与金属离子生成的络合物生成常数。制备并考察了以硒功能化杯芳烃为载体的银离子选择性电极的性能 ,发现以载体6为银离子选择性电子的载体 ,制成的膜电极 ,用作Ag+ 电位滴定Cl-的指示电极 。
Six selenium functionalized calix [4] arenes were used as the ionophores in solvent polymeric membrane. The calix [ 4] arene-metal ion complex formation constants In solvent polymeric membrane were determined directly by potentiometry with a two-layer sandwich membrane electrode. A silver ion selective electrode was prepared and characterized with selenium functionalized calix [ 4] arene as ionophore. The sixth ionophores was wed as the Ag+ selective electrode's ionophores, by using the Ag+-selective electrode as indicator electrode, the potentiometric titration was performed successfully.
