Electrochemical Behaviour of 4-aminoantipyrine at a Platinum Electrode: Kinetic Study

In this work, electro-oxidation of 4-Aminoantipyrine is investigated by using cyclic voltammetry technique at platinum electrode. The oxidation process was shown to be irreversible over at the pH range 2.0 and the number of electron transferred in the process was calculated. Kinetic and electrochemical parameters for the reaction such as standard heterogeneous rate constant (k⁰, 2.145 x10³ s^-1), anodic electron transfer rate constant (k_ox, 2.316 x 10³ s^-1), electron dependence of the current on scan rate was examined for the electro-oxidation of 4-Aminoantipyrine. Electron transfer coefficient (α, 1.38) of reaction and formal potential (E⁰, 0.5562 V) of electrode were evaluated under the influence of scan rate.
