Voltammetric Study Of Paracetamole Using Glassy Carbon Electrode

This paper describes the use of electro analytical techniques, cyclic voltammetry (CV), squarernwave voltammetry (SWV), and differential pulse voltammetry (DPV) in the study of thernelectrochemical behavior of paracetamol in aqueous media and at the glassy carbon electrode.rnThe electrochemical reaction was found to be irreversible, involving the transfer of twornelectrons. Aqueous phosphate buffer pH 7 was used as solvent and supporting electrolyte. Anrnoptimization of instrumental parameters was performed for the differential pulse and squarernwave voltammetric techniques. Differential pulse amplitude, pulse repeat time, and scan raternchosen for differential pulse voltammetry were 30 mV, 0.5 sec, and 5 mv/s respectively.rnSimilarly for square wave voltammetry, the amplitude, frequency, and step potential chosenrnwere 25 mV, 25 Hz, and 5 mV respectively. Finally the interference study of tablet was studiedrnat aqueous phosphate buffer of pH 7.0.
