摘要：

Ion - selective, liquid - membrane electrodes were studied using a novel impedance measurement technique. Evaluation of several commercially available membrane electrodes was carried out in detail as a function of frequency and of solution variables. From these studies, it was possible to identify and characterize some of the processes–e.g., electromigration and ion exchange–occurring within the membrane and at its interfaces. The data obtained suggest a possible means for the quantitative evaluation of fundamental electrode parameters, not accessible to potentiometric studies, and may lead to an experimental test of the current theories of ion-selective electrode operation. © 1969, American Chemical Society.
