Abstract
Valuable information on the selectivity behavior and the response mechanisms of analytically relevant neutral carrier membrane electrodes has been obtained from ion transport studies performed on the corresponding cation-selective membranes [9,10,15,16]. In electrodialysis experiments, the permeation of cations was induced by a transmembrane potential gradient, whereas in zero current countertransport systems, cations were driven by an oppositely directed flow of hydrogen ions, as induced by a pH gradient. The selectivity of ion transport was usually found to correlate with the potentiometric ion selectivity of the corresponding membrane electrodes [9, 10, 15, 16]. So far, virtually all experiments have concentrated on homogeneous PVC membranes.
