Removal lead (II) and chromium (III) Ions from aqueous solutions, by copper nanoparticles prepared using Capparis spinosa leaf extract

Abstract

The manufacture of copper oxide nanoparticles utilizing a green method is the subject of the study (environmentally friendly). The Capparis Spinosa plant's aqueous extract was used. The adsorption batch method was used to extract Pb (II) and Cr (III) ions from their aqueous solutions using this oxide. To describe and study the surface FT-IR, XRD, SEM, TEM, and AFM were among the methods used. were applied. All of the reflection peaks with relative intensities of different planes, as determined by XRD analysis, indicate CuO was found, and the spectral analysis revealed that the particle size produced was about (14.28 nm), which corresponded to those estimated by SEM and TEM. The sizes of the CuO particles were measured using SEM, TEM, and AFM, and they were found to be in the nanoscale range. The result of the impact of contact time, adsorbent dose, introductory fixation Finally, the thermodynamic bounds for the impact of temperature were calculated after considering pH and temperature.
