The possibility of use of cobalt(III) oxyhydroxide as an electrode modifier in electrochemical analysis of paraquat pesticide has been evaluated from the theoretical point of view. The electrochemical function mechanism has been suggested, and the correspondent mathematical model has been analyzed by means of linear stability theory and bifurcation analysis. It was shown that the cobalt(III)oxyhydroxide may be efficient cathode modifier for paraquat electrochemical reduction in neutral media. The steady-state stability is maintained in vast parameter region. The possibility for oscillatory and monotonic instabilities has also been verified.
