Study of Structure, Morphology, and Adsorption Properties of Ni0.2Zn0.8Fe2O4/GO Composite Prepared by Hydrothermal Method.

Abstract

Environmental degradation, particularly water contamination, is causing more and more serious issues with human health today. Fluoride ions and heavy metals are the main sources of water pollution. In the current study, an in-situ approach was used to generate a Ni0.2Zn0.8Fe2O4/GO nanocomposite that was examined for its ability to remove fluoride ions from water. Different techniques, such as X-ray diffraction (XRD), scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FTIR), and vibrating sample magnetometer (VSM), are used to characterize the produced nanocomposite. The produced ferrite reveals a face-centered cubic (FCC) structure in a single-phase spinal structure with no impurities in the sample, according to XRD data. The agglomerated and variably sized nanoparticles were observed in SEM micrographs. For Nickel zinc ferrite, the FTIR spectra indicate the absorption band of the octahedral and tetrahedral sites. A fluoride sensor was used in the nano synthesis lab to measure the amount of fluoride in the drinking water. The elimination of fluoride was conducted at various time intervals and in the pH range from 3 to 11. Finally, these ferrites have been employed to remove fluoride ions from several drinking water sources in Lahore, and the results have been excellent.
