Green preparation of Cu nanoparticles of the avocado seed extract as an adsorbent surface
The pollution of water with heavy metals is one of the most important health and economic problems globally. Therefore, the green preparation of Cu2+ nanoparticles from avocado seed extract can provide a method of adsorbing these heavy metals at the lowest cost and easily and safely. In addition, our research was motivated by the ability of these nanoparticles to inhibit some types of bacteria. In this study, seed extract was prepared and then reacted with copper2+ solution to obtain nanoparticles using the biosynthesis method. These nanoparticles were diagnosed by means of the FESEM, XRD, AFM, UV–vis, and FTIR techniques. FESEM images showed Cu peaks at about 1 and 9 keV of a crystal nature. The crystal size was 62.25 nm, according to the XRD results. The AFM images showed that the spherical particles had an average height of 21.289 nm. AUV–vis absorption band was observed at 530 nm, indicating copper2+ nanoparticles. The FTIR spectra showed the interaction of the seed extract with Cu2+ ions via a reduction reaction. The synthesized copper2+ nanoparticles demonstrated the inhibition of bacterial activity when used against E. coli and Staphylococcus aureus. Copper nanoparticles were used as a surface adsorbent for cadmium2+ ions of contaminated water, and the nanoparticles showed an active role.
