Abstract
Iron nanoparticles (FeNP) were synthesized using Acacia nilotica seedless pods extract. The synthesized FeNP were characterized by Fourier transform infrared (FTIR), UV/Vis spectroscopy, dynamic light scattering (DLS), electron microscopy (TEM), scanning electron microscopy (SEM), energy dispersive spectroscopy (EDS), and X-ray diffraction (XRD). The XRD pattern confirmed the synthesis of crystalline phase of α-Fe2O3. EDS spectroscopy showed the presence of elemental iron and oxygen, indicating that the nanoparticles are essentially present in oxide form. UV absorption in the range of 450–550 nm confirmed the formation of FeNP. DLS indicated an average FeNP particle size of 229 nm. The synthesized FeNP was tested for adsorption and oxidation degradation of methyl orange (MO) under different conditions and found to be effective in both degradation and adsorption processes. Furthermore, the synthesized FeNP has the potential to terminate the pathogenicity of several human opportunistic pathogens; belongs to gram-negative and gram-positive bacteria and one species of Candida as well.
Highlights
Iron nanoparticles have recently gained great research interest in environmental applications since it offers high surface reactivity due to high the surface area [1]
Iron nanoparticles have been applied for the catalytic degradation of chlorinated hydrocarbons such as trichloroethene, tetrachloroethene, and carbon tetrachloride from aqueous solutions [10,11,12]
FeNPextract formation was 4confirmed by the color change immediatelyconverted occurred from after the addition yellow of the to black in a few seconds demonstrating the synthesis of iron nanoparticles
Summary
Iron nanoparticles have recently gained great research interest in environmental applications since it offers high surface reactivity due to high the surface area [1]. Removal of organic pollutants [2,3,4], inorganic pollutants [5,6], and pathogenic bacteria [6,7,8,9] are among the most important applications. Many approaches have been reported for iron nanoparticles syntheses such as ball milling, sol-gel, high-energy electro-deposition [13], coprecipitation laser–induced gas phase pyrolysis, chemical vapor condensation, and freeze-drying [14]. The formation of iron nanoparticles can be attained through the reduction of iron organic or inorganic salt or via reduction of an iron oxide.
