Description
Summary:In this research, a core /shell from Fe2O3@MnO2-Nanoparticale was manufactured by Leek leaf extract in greenway biosynthesis. This method works as a reducing and covering agent. Fe2O3@MnO2 NPs have been confirmed as an effective antibacterial agent for both Gram-positive and Gram-negative bacteria. Synthesized nanoparticles were more efficient against gram-positive bacteria than gram-negative bacteria, with corresponding values of (31, and 24 mm) for klebsiella pneumoniae and Escherichia coli. Adsorption of metals (Pb, Cr, Ni, and Cd) by Fe2O3@MnO2 NPs trapped in calcium alginate was examined for use as a contaminant removal from water for the first time in Iraq. The results showed that nanoparticles trapped by alginate adsorbed more than alginate alone, and thus the Fe2O3@MnO2 nanoparticles (NPs) were able to remove lead, chromium, nickel, and cadmium from aqueous solutions with adsorption rate ranging between (84-99) %. Characteristics of synthesized nanoparticles were studied using (UV-visible) -spectroscopy, X-ray diffraction (XRD), and transmission electron microscopy (TEM).
