Demonstrates synthesis of magnetite nanoparticles in an eco-friendly way, suggesting their use in dye removal.
A facile and eco-friendly method for the synthesis of magnetite nanoparticles (Fe 3 O 4 NPs) via Co-Precipitation in the presence of aqueous leaf extract of Ficus hispida L. The optical, crystalline, structural morphology and magnetic behaviour of the synthesized Fe 3 O 4 NPs were characterized by Ultraviolet-Visible (UV-Vis), Fourier transform infrared (FTIR) spectroscopy, powder X-ray diffraction (XRD), field emission scanning electron microscopy (FESEM), and transmission electron microscopy (TEM) and vibrating sample magnetometer (VSM). The absorption spectrum reveals the peak at 379 nm, which confirm the formations of Fe 3 O 4 NPs. XRD results reveals the formation of phase pure Fe 3 O 4 NPs with cubic inverse spinel structure with crystallite sizes of 11.04 nm. The FESEM and TEM images clearly show that the spherical shape of Fe 3 O 4 NPs with average particles size of 10.96 nm. Bright circular rings in the selected area electron diffraction (SAED) pattern showed good crystallinity. VSM results show super paramagnetic behaviour of Fe 3 O 4 NPs. The synthesized Fe 3 O 4 NPs have potential to adsorption of Methylene Blue(MB)
