This study demonstrates the utilization of magnetic manganese ferrite (MnFe2O4) nanoparticles (NPs) as an effective solution for fluoride (F−) removal in industrial wastewater, particularly originating from the galvanizing industry. Fluoride in drinking water or wastewater originates not only from the Earth’s crust but also from various industrial sectors, including semiconductor, electroplating, steel, glass manufacturing, fertilizer, and ceramics industries. Effluents from these sectors can contain excess fluoride ions. Hence, finding efficient methods for fluoride removal is crucial to protect human health and the environment. Magnetic MnFe2O4 NPs were synthesized using the microwave-induced combustion method, providing a novel nanosized adsorbent for de-fluoridation in this study. Batch-mode experimental studies were conducted to investigate the effects of adsorbent dosage, contact time, and pH on the adsorption performance. The optimal dosage and contact time for fluoride removal using these NPs were determined as 1.5 g/L and 60 min, respectively. Additionally, the optimal pH for fluoride removal was identified as 3. Under these conditions, the de-fluoridation efficiency and adsorption capacity were measured as 78.38% and 6.11 mg/g, respectively. These findings highlight the effectiveness of manganese ferrite NPs as an adsorbent for mitigating fluoride contamination in industrial wastewater, particularly in the galvanotechnic industry.
