![]() ![]() Thermodynamic parameters also were derived as spontaneous chemisorption endothermic processes. The maximum monolayer adsorption capacity was 122.9 mg/g according to the Langmuir isothermal model, and the kinetic mechanism was pseudo-second-order. The following strategic methodology for maximum Xim removal was conducted to be solution pH 4, Cu NPs dosage 30 mg, Xim concentration 100 mg/L, and absolute temperature 313 K. As a potential utility of the biosynthesized Cu NPs as nano adsorbents to the removal of the Cefixime ( Xim) from the pharmaceutical wastewater adsorption studies and process parameters were being investigated. Energy dispersive spectroscopy (EDX) was conducted to investigate the elemental composition of the Cu NPs. ![]() Transmission electron microscopy (TEM) analysis also was used to assess the cubic shapes at a particle size of 15.1 ± 8.3 nm and a crystallinity index about equal to 2.0. ![]() Morphological analysis was investigated confirming the nano-characteristic properties of the Cu NPs as polycrystalline cubic agglomerated shapes in scanning electron microscopy (SEM) analysis. Electrical conductivity was conducted assuring the semiconductor nature of the biosynthesized Cu NPs. surface plasmon resonance revealed the absorption peak at 324 nm with an energy bandgap of 3.47 eV. Infrared spectroscopy (FT-IR) analysis confirmed the capping and stabilization of the Cu NPs bioreduction process. X-ray diffraction (XRD) results confirmed the production of the pure crystalline face center cubic system of the Cu NPs with an average crystallite size of 8.41 nm. The aim of this paper is the green synthesis of copper nanoparticles ( Cu NPs) via Quinoa seed extract. ![]()
