All‐solid‐state chloride‐selective electrode with poly(pyrrole) solid contact

Abstract
The responses of all‐solid‐state potentiometric chloride sensors with an internal poly(pyrrole) contact and a plastic membrane with methyltridodecylammonium chloride were investigated. The influence of the poly(pyrrole) doping anion was studied. Chloride‐selective electrodes with a poly(pyrrole) solid contact were characterized by good stability. The selectivity coefficients for this electrode are slightly better than for the internal solution electrode.
