ABSTRACT
A system was designed based on a sensing process for continuous release of . A polymer-modified electrode was prepared by electropolymerization of aniline onto a platinum electrode from a solution containing the monomer and
to form a layer of polyaniline/
(PA/FCN). The FCN incorporated into the polymer film can be released by applying a sufficient potential. An FCN-selective electrode was used as the counter electrode of the system. As the sensor exhibits potentiometric response to the FCN ions, the generated potential causes the release of
from the polymer film electrode. The system was examined as a continuous releaser of
for study of a chemical oscillator as a typical application.
