REMOVAL OF As(III) FROM INDUSTRIAL WASTEWATERUSING BaFe12O19 NANOPARTICLES
The main public health problem is arsenic, As (III) contamination of drinking water. In the current scenario, nanoparticles have emerged as a promising candidate for As(III) decontamination. This study provides acomprehensive solution for the use of nanoparticles (NPs) of barium hexafluoride (BaFe12O19) for thedecontamination of As(III). Herein, NPs were synthesised by hydrothermal synthesis at low temperature andcharacterised by FTIR, XRD, Particle Size Analyser (PSA), FESEM, TEM, and EDX. Among the key observations, PSA, TEM and FESEM revealed a consistent distribution of particle sizes with a 65 nm average diameter. EDXanalysis confirmed the presence of the main chemical components Ba, Fe, and O. BaFe12O19 NPs achieved a 55%Ar removal from industrial wastewater and showed five times higher As(III) removal effectiveness than the commercial Fe₃O₄ NPs. These findings demonstrate the potential of BaFe12O19 NPs as a promising As(III)-remediatingadsorbent and provide a basis for developing cost-effective nanomaterials for the treatment of industrial wastewater. In addition, this finding provides insights for future research to improve the adsorption efficiency and practical implementation in sustainable water purification systems.
