Item Determination of paracetamol on electrochemically reduced graphene oxide–antimony nanocomposite modified pencil graphite electrode using adsorptive stripping differential pulse voltammetry(MDPI, 2022) Leve, Zandile D.; Jahed, Nazeem; Sanga, Nelia A.A simple, highly sensitive, accurate, and low-cost electrochemical sensor was developed for the determination of over-the-counter painkiller, paracetamol (PC). The enhanced sensing capabilities of the developed sensor were fabricated by the single-step modification of disposable pencil graphite electrodes (PGEs) with the simultaneous electrochemical reduction in graphene oxide and antimony (II) salts. For this purpose, an electrochemically reduced graphene oxide–antimony nanoparticle (ERGO-SbNP) nanocomposite material was prepared by trapping metallic nanoparticles between individual graphene sheets in the modification of PGEs.
