In this work, the possibility for sunset yellow electrochemical determination, assisted by the composite of VO(OH) with conducting polymer, has been evaluated theoretically. The correspondent balance equation model of three variables has been developed and analyzed by means of linear stability theory and bifurcation analysis. The oscillatory and monotonic instabilities are shown to be manifested more probably than for the simplest case. The double electric layer (DEL) is influenced by the cyclic changes of ionic force observed during ionic forms' chemical transformation. Nevertheless, the CP – VO(OH) composite may be considered an efficient electrode modifier for yellow sunset determination.
