Abstract

Current study investigates hydrothermally prepared SrBa0.3Fe1.7O4 for the adsorption of fluoride ions (F−1) from drinking water. X-ray diffraction patterns show given sample has a single-phase spinel structure. Scanning electron microcopy confirmed nano-sized particles in the range 12–15 nm. Fourier transform infrared spectroscopy results indicate presence of small absorption peaks due to low temperature sintering and useful elastic parameters have been analyzed as well. The Magnetic Hysteresis was measured by using Vibrating sample magnetometer between -9KOe to 9 KOe. The results revealed the soft magnetic behavior. Prepared ferrites have been investigated for time dependent and isothermal adsorption models. Pseudo second order and Temkin isotherm model best fitted the experimental results. Finally, these ferrites have been used to remove the fluoride ions from different drinking water sources in Lahore and have shown promising results.
