Abstract :
The system with the sucralose electrochemical detection on the overoxidized polypyrrole has been described mathematically. The correspondent mathematical model has been developed and analyzed by means of linear stability theory and bifurcation analysis. It
was shown that the overoxidized polypyrrole may serve as a modifier for sucralose electrochemical detection in neutral solutions, participating in the electroanalytical process as a substrate. The electroanalytical process is diffusion-controlled. The possibility of oscillatory and monotonic instabilities has also been verified.
