TKACH, Volodymyr V; OJANI, Reza; NECHYPORUK, Vasyl´ V  and  YAGODYNETS´, Petró I. The mathematical study of the electrochemical nitrite sensorbased on poly(P-aminoacetanilide). Rev. Fac. Ing. UCV [online]. 2015, vol.30, n.1, pp.181-188. ISSN 0798-4065.

The work of the electrochemical sensor of nitrite based on its electrochemical reduction over poly(p-aminoacetanilide modified) carbon paste electrode, was mathematically described. The corresponding model was described by means of the linear stability theory and bifurcation analysis. The steady-state stability requirements and oscillatory and monotonic instabilities´ conditions were derived from the analysis of the model.

Keywords : conducting polymers; electrochemical reduction; electrochemical sensors; stable steady-state; bifurcation analysis.
