Solid-state ion sensor |
摘要 |
The solid-state ion sensor of the present invention comprises an inner electrode comprising a metal and a water-insoluble salt of the metal which covers at least a part of the surface of the metal, an ion-selective membrane selectively responsive to the ion species to be determined, and an intermediate layer comprising a hydrophilic polymeric membrane provided between the inner electrode and the ion-selective membrane. The inner electrode comprises a metal and a halogenide of the metal which covers at least a part of the surface of the metal. In the hydrophilic polymeric membrane is dispersed a hydrophilic electrolyte having halogen ions same as or different from those constituting the halogenide with the weight ratio of the electrolyte and the polymer [(electrolyte) wt. %/(polymer) wt. %] being at least 1/100. A polymeric ion-conductor can be used as the hydrophilic polymeric membrane.
