Description
Summary:W-hexaferrite BaCo 2 Fe 16 O 27 was prepared using the citrate nitrate combustion method. The sample was characterized using XRD, SEM, EDX and elemental mapping. XRD confirmed that the sample was synthesized in a single phase hexagonal structure with an average crystallite size 37.39 nm. SEM images of the sample show a spongy morphology with the agglomerated grain owing to dipole interaction between the crystallites. The magnetic properties of BaCo 2 Fe 16 O 27 were studied using H-M hysteresis loop and the DC magnetic susceptibility. The sample has a ferrimagnetic behavior with saturation magnetization 64.133 emu/g. The magnetic properties of BaCo 2 Fe 16 O 27 are originated from the Fe 3+ –O–Fe 3+ superexchange. The synthesized sample is used as an adsorbent to remove the heavy metal Pb 2+ from water. BaCo 2 Fe 16 O 27 has Pb 2+ removal efficiency 99% and 28% at pH 8 and 7 respectively. The Langmuir and Freundlich isotherms were used to analyze the experimental data. The Freundlich adsorption isotherm fitted the experimental data well.
