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.
