The theoretical description for diclofenac electrochemical determination over an undoped conducting polymer in doping conditions. In the basic solution, diclofenac ion enters the polymer matrix as a dopant. The doping is followed by hydrolysis and electrooxidation of the resulting phenolic ion, accompanied by the grafting to the proper polymer backbone. Analyzing the correspondent mathematical model by linear stability theory and bifurcation analysis, we confirm that the electroanalytical process remains efficient despite the high probability of the oscillatory behavior.
