Abstract

In the current effort, the nanoparticles of copper oxide (CuO/NP) were obtained by the co-precipitation procedure and characterized by the scanning electron microscope (SEM) X-ray powder diffraction (XRD), and energy dispersive spectroscopy (EDS) strategys. The CuO/MCPE was polymerized by utilising the N-Cetyl-N,N,N-trimethylammonium bromide (CTAB) surfactant, has been studied by cyclic voltammetric (CV) and linear sweep voltammetric (LSV) techniques. The analytical factors, such as pH, sweep rate, and concentration were evaluated. The limits of detection (LOD) and quantification (LOQ) was determined under optimized conditions and the values were arise to be 0.1179 µM, 0.391 µM, and 0.1942 µM, 0.6475 µM for Catechol (CC) and Hydroquinone (HQ), respectively. Moreover, the CuO/ pretreated CTAB/MCPE was employed for the sensitive and selective determination of CC and HQ in true samples.
