In this work, the possibility of the electrochemical determination of salicylic acid on conducting polymer – CoO(OH) composite has been evaluated. The electrooxidation mechanism includes the gradual phenolization of the aromatic ring carbon atoms 3 and(or) 5 with further electrooxidation to the correspondent quinone. The analysis of the correspondent mathematical model utilizing linear stability theory and bifurcation analysis confirms the conducting polymer composite efficiency in salicylic acid determination in a wide concentration range. On the other hand, the oscillatory behavior in this system is possible, but its realization and feature strongly depend on the analyte nature and background electrolyte composition.
