Comparative analysis of the Magnesium Ferrite (MgFe ₂ O ₄ ) nanoparticles synthesised by three different routes

Abstract

The toxicity of arsenic in drinking water is hazardous for human health. Different strategies are used for arsenic removal from drinking water. Nanoparticles with higher adsorption capacities are useful for arsenic remediation. In the current study, magnesium ferrite nanoparticles were synthesised by three different methods followed by their characterisation XRD, SEM, and EDX. The SEM morphology and the porosity of magnesium ferrite nanoparticles were best in case of autocombustion method. These particles had an average particle size of about 20-50 nm with spherical shape. These particles showed efficient remediation of arsenic up to 96% within 0.5 h. However, the co-precipitation and sol-gel-based nanoparticles showed arsenic remediation upto85 and 87% at 0.5-h time point. Moreover, the minimum inhibitory concentration of nanoparticles against two strains E.coli and Pseudomonas aeruginosa was found to be4.0 mg/L of these nanoparticles. However, the sol-gel-based nanoparticles showed efficient anti-microbial activity against E.coli at 4.0 and 8.0 mg/L against Pseudomonas aeruginosa. The co-precipitation-based nanoparticles were least efficient both for arsenic remediation and antimicrobial purposes. Thus, the synthesised auto-combustion-based nanoparticles are multifunctional in nature.

Fabrication, characterization, and antibacterial activity of ferrite, chromite, and aluminate nanoparticles

“…As mentioned above, the chemicals used during the synthesis contain chloride ions; therefore, the precipitate was washed with deionized water to remove Cl. Consequently, the detection of an additional signal related to Cl reveals that this element was not completely removed, as reported by Tariq et al [75]. Moreover, it is obvious that the amount of Mg in sample A is higher than that of Zn and Co, confirming the formation of MgO secondary phase.…”

Spectroscopic, Magnetic and Morphological studies of MgFe2O4 Nanopowder

“…The structural and magnetic properties of MgFe2O4 obtained from transmission electron microscopy, XRD, Mossbauer spectroscopy, and magnetometry have been reported [11]. Numerous studies [12,13] on MgFe2O4 nanoparticles described their nanostructures and many properties, including IR, XRD, SEM, and VSM. N-Suresh kumar [14] synthesized nickel substituted magnesium ferrites by auto combustion method and also studied dielectric and magnetic properties.…”
