| Summary: | ISEs (Ion-selective electrodes) were found to be effective sensors for the detection of a variety of
inorganic and organic cations and anions. These electrodes are simple, inexpensive, and easy to
use. However, challenges associated with robust, reliable, and stable potential sensor
development are still an ongoing research effort. This study is focused on addressing potential
stability and sensor resistance to water formation at the solid-contact | membrane interface by
introduction of chitosan in the design of the ion-selective electrode. Conducting polymer
(poly(3,4-ethlyenedioxythiophene)) was selected as a model compound for solid contact material
in ISEs. Water layer tests and electrochemical impedance spectroscopy were used to evaluate the
potential stability of different types of ISEs. |
