The Mathematical Evaluation for the Use of the Conducting Polymers, Saturated with Radical Sites, in Carbendazim Electrochemical Detection

The possibility of use of conducting polymer (CP), saturated by radical growth centers, as an electrode modifier for carbendazim electrochemical detection has been evaluated by mechanistic way. A mechanism of its electrochemical transformation has been suggested and two mathematical models for oxidation and reduction stages were developed and analyzed by means of linear stability theory and bifurcation analysis. It was proved that, despite of the mechanism´s hybrid character, the conducting polymer, saturated with radical sites, may be an excellent electrode modifier for carbendazim electrochemical detection. The possibility of the oscillatory behavior in this system has also been verified, and it may be possible on both radical formation and recombination stages, being caused by surface and electrochemical factors.
