Abstract
Disclosed is a method for regenerating an ion-selective electrode equipped with an ion-selective membrane which is formed of a polymer membrane containing an ion-selective material and plasticizer, which method comprises supplying to the ion-selective membrane a regenerating plasticizer which is either identical in every aspects or analogous in effects to the first-mentioned plasticizer and is capable of dissolving the ion-selective material therein and imparting flexibility to the ion-selective membrane. Also disclosed are several embodiments of ion-selective electrodes and ion-concentration analyzers containing means for practicing said method.
