“…Ethylene Glycol (EG) is an alcohol widely used in industry due to its physical and chemical characteristics such as high flash point, low freezing point, low volatility, low flammability, thermodynamically stable and high availability 1 . In the plastic industry, the EG is a precursor of the polyethylene terephthalate very used to produce PET bottles, in the automobile industry it is the main component of the cooling fluid in combustion engines [2][3][4] , in the petroleum industry it is used as a hydrate formation inhibitor [5][6][7] , in other sectors as solvent 8 and as antifreeze on airport and highway runways 2 .…”

An electrochemical sensor based on a modified glassy carbon electrode (GCE) with reduced graphene oxide and Ni-Au nanoparticles (Ni(OH) 2 /AuNp/rGO/GCE) was developed for the determination of ethylene glycol. The graphene oxide was reduced electrochemically at the electrode surface by chronoamperometry, the gold nanoparticles were deposited by chronopotentiometry while the nickel hydroxide nanoparticles were deposited by cyclic voltammetry. The characterization of graphene oxide was performed by Raman spectroscopy, X-ray diffraction (XRD) and transmission-mode scanning electron microscopy (TSEM), while the modified electrodes were characterized by scanning electron microscopy (SEM) and electron dispersive spectroscopy (EDS) analysis. The determination of ethylene glycol was performed by cyclic voltammetry due to the regeneration of the active sites, preventing loss of the sensor signal. The modified GCE with rGO and Ni(OH) 2 /AuNp showed a good performance obtaining a linear range of 0.24 to 1.4 mmol L -1 with a correlation coefficient of 0.9903, limits of detection and quantification (49 and 162 µmol L -1 , respectively) and high stability with 500 continuous analysis cycles.
