Abstract / The electrochemical behaviors .of paracetamol on glassy carbon electrodes (GCE) were investigated by cyclic Voltammetry (CV), square wave Voltammetry (SWV), and differential pulse Voltammetry (DPV). Aqueous phosphate buffer (pH 7) was used as solvent and supporting electrolyte. The electrochemical reaction was found to be quasi-reversible, involving the transfer of two electrons. Several parameters were investigated for studying the redox behavior of paracetamol like the effect of pH, concentration and scan rate. As the pH increases the anodic peak potential drastically shifts to the negative potential, which indicates that hydrogen ion takes part in the electrochemical oxidation of Paracetamol. An optimization of instrumental parameters was performed for the differential pulse and square wave voltammetric techniques. A direct relationship has been observed between concentration and the anodic peak current. Further work should be conducted to study other properties of Paracetamol and any body who is interested to study the property of Paracetamol using voltammetric technique can use preferable SWV technique to achieve better result than CV and DPV.
