Abstract :
In the present work, the modified nickel electrode was electrochemically fabricated and tested for the electro-oxidation of paracetamol in alkaline media. The methods of cyclic voltammetry (CV), chronoamperometry (CA), and impedance spectroscopy (EIS) were used to determine kinetic parameters such as transfer coefficient (?), the catalytic reaction rate constants (k), and the diffusion coefficient of paracetamol in the bulk of solution. The electrochemical results showed that the modified nickel electrode had a high electrocatalytic activity for the electro-oxidation of paracetamol around 400 mV/Ag.AgCl in alkaline media and the diffusion coefficient of paracetamol was obtained to be 3×10-6 cm2.s-1. It means that the modified nickel electrode is highly sensitive toward the detection of paracetamol.
