ABSTRACT

The preparation of graphene oxide and the modifcation of its surface directly with copper pentacyanonitrosylferrate (III) nanoparticles are presented in this work, as well as the characterization of the materials using Fourier-transform infrared spectra, X-ray difractometry and scanning electron microscopy techniques. Beyond that, the study on the electrochemical behavior of the dispersed bimetallic complex on the graphene oxide, as known as GOCuNP, surface was carried out by the cyclic voltammetry technique. The graphite paste electrode modifed with GOCuNP was successfully applied in the detection of hydrazine, presenting limit of detection of 1.58×10–6 mol L−1 at concentration range of 1.00×10–5 to 5.00×10–3 mol L−1 of hydrazine, being so the proposed bimetallic complex formed can be considered as a potential candidate for the manufacturing of electrochemical sensors for hydrazine detection.
