Abstract :
The precipitation method was utilized to prepare MgO nanoparticle (MgO/NPs) without using surfactant in this study, the MgO/NPs was examined by XRD, SEM, and EDS analysis. The MgO/MCPE was developed and used for the oxidation of paracetamol (PA) in presence of ascorbic acid (AA) study by using cyclic voltammetric (CV) and differential pulse voltammetric (DPV) techniques. Finally, the developed sensor shows good electrocatalytic performance in pH and scan rate studies. From the concentration study for the voltammetric determination of PA, the limit of detection was found to be 4.33 μM for PA at MgO/MCPE, the practical purpose of the MgO/MCPE was utilized to evaluate PA in real sample analysis.
