CuCrO4 Nanoparticles Composite Modified Carbon Paste Electrodes for Sensitive Detection of Paracetamol: A Cyclic Voltammetric Study

Abstract An electrochemical sensor containing carbon paste electrode (CPE) for paracetamol is developed and modified with the CuCrO4 Nanocomposites. The synthesised CuCrO4 Nanocomposites was discussed with X-Ray Diffraction studies. Experimental studies such as scan rate, concentration and pH was studied by using cyclic voltammetric method. The CuCrO4 Nanocomposites modified CPE (CuCrO4 Nanocomposites MCPE) exhibited excellent electrocatalytic response towards the oxidation of paracetamol (PC). Over potential for oxidation of PC was minimised which considerably enhance the current response on the CuCrO4 Nanocomposites MCPE when compared with bare carbon paste electrode (BCPE). Scan rate study for PC discuss the process of the electrode. Linear calibration curve was obtained with the range of 2 μM to 14 μM having the detection limit and quantification limit value of PC is discussed with CuCrO4 Nanocomposites MCPE. This study shows that electrochemical oxidation of PC at CuCrO4 Nanocomposites MCPE is pH dependent process.
