Abstract
This paper reports a voltammetric sensor based on copper oxide nanoparticles on nitrogen-doped reduced graphene oxide nanocomposite (N-rGO/CuO)-ionic liquid modified carbon paste electrode (N-rGO/CuO-ILCPE) for determining the hydroquinone (HQ). The N-rGO/CuO was prepared by a facile protocol, followed by characterization via fourier transform-infrared (FT-IR) patterns, field emission-scanning electron microscopy (FE-SEM), energy dispersive X-ray (EDX), and X-ray diffraction (XRD) analysis. The electrochemical behaviour was linearly symmetrical to various hydroquinone levels (1.0-600.0 mu M) with a narrow limit of detection (LOD = 0.25 mu M). The diffusion coefficient was also estimated to be 4.1 x 10(-6) cm(2)/s. The N-rGO/CuO-ILCPE was impressively applicable in determination of hydroquinone in the real specimens.
