ION SENSOR.

摘要

An ion sensor which is prepared by covering a conductive base (1) with a redox function layer (5) composed of an electrolytic polymer membrane of a hydroxy or amino compound having a biphenyl skeleton, or a mixture thereof, etc., and covering the surface with an ion-selective layer (4). This ion sensor suffers less dissolution of the redox function layer (5) into the ion-selective layer (4), thus showing stable properties and having a long life.
