Abstract

For the first time, abametapir cathodic electrochemical determination on a squaraine dye-modified electrode, reinforced by vanadium (IV) oxide, has been described theoretically. The mechanism for the electroanalytical process has been suggested, and the correspondent mathematical model has been developed and analyzed by means of linear stability theory and bifurcation analysis. Taking into account that the process is carried out in acidic media, the abametapir is thereby transformed to an ionic form, converted, by that, to another non-ionic. Both of the processes influence the double electric layer ionic force by cyclic influences, being therefore responsible for the oscillatory behavior. Nevertheless, the steady-state stability is easy to obtain and maintain, confirming that the electroanalytical process is stable.
