FABRICATION AND ELECTROCATALYTIC APPLICATION OF NI-MODIFIED ELECTRODE TOWARD DETECTION OF PARACETAMOL
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 a...
