前人观察到:在络合剂存在下,离子选择性电极的检测下限明显降低。这使我们有可能更方便的用离子选择性电极电位法来研究金属络合物。虽然,浓差电池电位法研究金属络合物是一较古老的方法,但最近苏联学者 Kepe(?)uyk 和Мохнатова仍提出基于浓差电池电位滴定的离子选择性电极法来研究金属络合物,测定了稳定常数,他们的 Previous observations: in the presence of complexing agent, the lower limit of detection of ion-selective electrode was significantly reduced. This makes it possible for us to study metal complexes with ion-selective electrode potentials more conveniently. Although concentration-cell potentiometry is an ancient method for the study of metal complexes, the recent Soviet scholar Kepe (?) Uyk and Мохнатова still proposed an ion-selective electrode based on concentration-cell potentiometric titration to study metal complexes , Measured the stability constants of them
