Optical and Morphology Properties of the Magnetite ( Fe₃O₄) Nanoparticles Prepared by Green Method

Abstract

Magnetite nanoparticles have been synthesized by a green method. For this process, ferricchloride hexahydrate, ferrouschloride tetrahydrate (2/1 molar ratio) solution was mixed with different amounts of carob leaves extract and NaOH solution was added to get pH(2, 5,8 and 11) heated for 30 min at (30,60,80 and 100) °C . In this report, a description was introduced for the synthesis of Fe304 nanoparticles (NPs) in order to obtain the optimum (pH8 ,temperature and amount of extract) that have small particle size MNPs. The magnetite nanoparticles were characterized by UV-Vis absorption spectroscopy, through Field emission scanning electron microscopy (FESEM) and Atomic Force Microscope (AFM). In UV-Vis spectroscopy, the absorbance of surface plasmon resonance (SPR) of magnetite nanoparticles synthesized with different parameters, were observed a single visible peak located in the range of (290-519) nm and it was related to spherical monodisperse, peak shifts to shorter wavelength (blue shift) with change parameter. FESEM images confirm the Fe304 NPs synthesized with different parameters were spherical shaped and lower than 50 nanoscale. AFM images of magnetite nanoparticles with different parameter. It is observed that each nucleus magnetite Nanoparticles is spherical in geometry

Optimization and Modeling the Processes of Green Magnetite Nanoparticle: Synthesis, Photo Catalysis Tendency and Kinetics of Removing Organic Dye from Aqueous Solutions

“…The result showed a maximum absorption peak around 350 nm; this indicates the formation of Fe3O4 NPs. Similar UV results for magnetite NPs were found in literature (Yew et al, 2016) (Abdallah et al, 2021) (Sathishkumar et al, 2018).…”

“…So, the optimum condition for synthesized Fe 2 O 3 NPs is at 70 °C that shows a shorter wavelength with perfect absorbance intensity observed in Figure B. Therefore, the wavelength of 370 nm was selected as an optimum SPR peak at a 70 °C temperature and pH 10 for the synthesis of Fe 2 O 3 NPs …”

Nanocomposite-Supported Polymeric Composites Prepared with Different Deposition Bases: Characterization and Application in X-ray Shielding

“…This is due to the increase in the surface area and the scattering of magnetite NPs within the polymer matrix, thus increasing the possibility of radiation interaction with the material, absorbing the energy of the photon, and this agrees with findings in Refs. [54,55]. The effect of the operating voltage can be seen from the values of the attenuation properties in Figures 12-15 and it is found that by increasing the voltage values, the ability of the nanocomposite to attenuate the rays decreases.…”
