Galvanostatic Polarization of All‐Solid‐State K+‐Selective Electrodes with Polypyrrole Ion‐to‐Electron Transducer

Influence of galvanostatic polarizations on potential vs. logarithm of ion activity dependences of all-solid-state ion-selective electrodes with conducting polymer ion-to-electron transducer was studied. As a model system K+-sensor with polypyrrole solid contact and poly(vinyl chloride) based membrane containing valinomycin was chosen. The influence of the lipophilic salt included to the membrane composition was of special interest.
