Electrochemical Investigation of Paracetamol at Poly(Glycine) Modified Carbon Paste Electrode: A Voltametric Study

Chethan M kuskur, Kumara Swamy BE and Jayadevappa H

The carbon paste electrode was modified by electropolymerisation of 1 mM Glycine in 0.2 M Acetate buffer solution (ABS) at pH-5. The voltammetric response of Paracetamol (PA) at Poly(Glycine) Modified carbon paste electrode (MCPE) shows excellent electrocatalytic activity when compared to bare carbon paste electrode (BCPE) at sweep rate of 100 mV/s-1. From the study of scan rate variation the electrode process was found to be diffusion controlled. The concentration effect of paracetamol was studied. The simulations determination of PA, DA and AA in their sample mixture was analyzed by using both cyclic voltammetric and differential pulse voltammetric techniques.
