Tuning the Properties of Ba-M Hexaferrite BaFe11.5Co0.5O19: A Road Towards Diverse Applications

Abstract The development of hexaferrite nanoparticles is scrutinized as potential sorbents for the removal chromium (Cr) ions from aqueous chromium-containing solutions in a batch adsorption experiment. transition metal Co doped BaFe 12 O 19 compounds (BHF) have been synthesized successfully via citrate auto combustion technique. structure, surface morphology and magnetic properties samples were studied. X-ray diffraction pattern ratifies existence hexagonal phase main prepared samples. average crystallite sizes are found range 47–49 nm. high-resolution transmission electron microscopy (HRTEM), well Fourier, transform infrared spectrophotometry results confirm an M-type structure existing. χ-T indicates temperature-dependent ferromagnetic behavior BHF nanoparticles. derivative shows single temperature Tc at 698 °C, 710 °C BCHF respectively. utilized adsorbent Cr (VI) solution. maximum capacity (qm) on nano higher than that various other adsorbents testified literature. pseudo-second-order kinetic model gives better fit to experimental data.
