Abstract: An interesting electrochemical potentiodynamic amperometric heavy metal concentration monitoring system based on overoxidized polypyrrole has been proposed. A model describing the electrochemical behavior in potentiostatic mode of the system with metal complex oxidation during the formation has been developed and analyzed using linear stability theory and bifurcation analysis. It has been shown that the oscillatory behavior may occur more probably in this system than in similar ones due to the cyclical electrode surface impedance change during the chemical and two electrochemical stages. Nevertheless, this system may be efficient for heavy-metal concentration monitoring in vitro and in vivo.
