The electrochemical determination of permethrin in neutral solutions using CoO(OH) has
been investigated. A corresponding mathematical model was developed and examined through linear
stability theory and bifurcation analysis. The results indicate that the analytical process may be more
efficient on CoO(OH) in neutral media than under alkaline conditions. The electrochemical response
should remain clear and readily interpretable. Furthermore, both oscillatory and monotonic instabilities
were confirmed. These oscillations arise from DEL effects associated with the electrochemical step and
the hydrolysis chemical stage.
