- Abstract
Introduction: For the first time, the possibility of nereistoxin electrochemical determination on a CoO(OH)/CP-modified electrode has been given. Proposal: The electrooxidation is carried out gradually by the sulfur atoms, leading to the ring cleavage and formation of a disulfenic acid, followed by a disulfonic acid formation. Result: The analysis of the correspondente model by means of the linear stability theory and bifurcation analysis confirms the efficiency of cobalto oxyhydroxide and conducting polymer for nereistoxin determination. On the other hand, the probability of the oscillatory behavior in this system is enhanced, due to the formation of the new ionic forms.
