Nanostructured Iron Oxides: Structural, Optical, Magnetic, and Adsorption Characteristics for Cleaning Industrial Effluents

Globally, efforts are being made to upgrade and improvise the current wastewater treatment technologies. Industrial is generated exponentially, owing expansion in chemical industries civilizations necessitating remediation prevent further environmental damage lower associated human risks. In this work, iron oxide nanoparticles (IONPs) have been developed employed as an efficient nanocatalyst for heavy metal adsorption via route. The shape, absorbance optical, crystal phase, magnetization of as-prepared magnetic nanostructures were characterized using XRD (X-ray diffraction), UV-Vis (ultraviolet-visible), HRTEM (High-resolution transmission electron microscopy), FTIR (Fourier transfer infrared spectroscopy), VSM. Further, ability remove bulk metallic elements considering cadmium (Cd), lead (Pb), zinc (Zn), chromium (Cr), copper (Cu), nickel (Ni), present industrial effluents, studied. Maghemite Fe2O3 phase having R-3c group observed results. An identical shape spherical determined TEM including ≈21 nm pure Fe2O3. A removal % was studied by ICP-OES, showed a Cr (61.2%), Cd (98%), Cu (66%), Ni (64%), Zn (97%), Pb (98%) ability. application such monitored nanomaterials effluent cleaning sewage discharge emitted labs petrochemical could be expanded.
