Abstract

The co-precipitation method was used to synthesize lithium-doped copper oxide nanocomposites. Several techniques analyze these materials. X-ray diffraction was used to assess the crystal structure and nanoscale dimensions. Scanning electron microscopy (SEM) and energy dispersive spectroscopy (EDS) determined the elemental composition. The study also examined the effectiveness of the CuO-LiO nanocomposite in adsorbing blue crystalline dye from an aqueous solution. Adsorption was tested using UV-Vis spectroscopy with an equilibrium time of 30 min and a surface weight of 0.015 g. Results showed that the adsorption percentage ranged from 19.5% to 48% at temperatures between 298 and 323 K. The thermodynamic functions ΔH, ΔG, and ΔS were calculated to determine the effect of temperature, revealing an endothermic adsorption process.
