ion-selective membrane

https://doi.org/10.1351/goldbook.09119
Membrane with controlled permeability to a particular ion covering an electrode, or separating two electrolyte solutions.
Note: The potential difference of an ion-selective electrode derives from differences in activity of an ion at each side of the membrane.
