Abstract

The theoretical description for the ephedrine electrochemical determination over a CoO(OH)-modified polynaphthoquinonic conducting polymer electrode has been given. The correspondent mathematical model has been hereby developed and analyzed by means of linear stability theory and bifurcation analysis. It has been shown that cobalt (III) oxyhydroxide may be efficient electrode modifier for either ephedrine electrochemical determination, or for the electropolymerization of its oxidation product. As for the oscillatory behavior, its probability will be equal to that for the simplest similar systems.
