Removal of Fluoride in Water Using Sustainable Strontium Ferrite Graphene Nano Composite

Nowadays, readily manageable and ecologically safe adsorbents are in demand for the removal of fluoride from contaminated water sources since prolonged exposure to fluoride above the permitted limit causes both dental and skeletal fluorosis. In the current investigation, Strontium Ferrite Graphene Composite (SF-GOC) has been synthesized and well characterized by physico-chemical characterization methods such as XRD, FTIR, SEM-EDX, TEM, AFM, TGA, and nitrogen adsorption-desorption study. It optimized several parameters such as adsorbent dosage, reaction time, initial fluoride concentration, pH, and temperature used for the adsorption application of fluoride from water. The leaching experiment showed that no secondary pollution was observed due to the use of transition metals strontium and iron. The adsorption study was carried out and from the Langmuir isotherm (R-=(2) 0.9848), the obtained maximum adsorption capacity was 5.6 mg/g. Under ideal conditions, with the help of a UV-Visible spectrophotometer, the maximum fluoride removal was found to be 97.5%, indicating that SF-GOC can be employed as an effective, thermally stable, recyclable, and environmentally acceptable nanocatalyst for the simple removal process of fluoride from contaminated water.
