- Abstract
Introduction: The possibility of resveratrol electrochemical determination, assisted by cobalt (III) oxyhydroxide and its composites with conducting polymers has been evaluated from the theoretical point of view. Methodology: The correspondent mathematical model has been developed and analyzed by means of the linear stability theory and bifurcation analysis. Results: The analysis of the model confirms that the cobalto oxyhydroxide may serve as an efficient electrode modifier for resveratrol electroanalytical determination. Conclusion: Depending on the analysis conditions, the electroanalytical process may be either diffusion- or kinetically controlled. On the other hand, the oscillatory behavior is also possible being even more probable than in the simplest cases, due to the impact of the chemical and electrochemical stages on DEL.
