Water pollution with azo dyes is one of the most important environmental and health challenges in the world, requiring efficient and sustainable treatment methods. Traditional methods often do not provide complete removal of pollutants due to high consumption of chemicals and energy. In this research, a magnetic nanocatalyst based on MIL-88 and reinforced with metal oxide is designed and synthesized. The physical, structural and chemical properties of the nanocatalyst are investigated with appropriate identification methods and the accuracy of sample formation is confirmed. The efficiency of the catalyst in removing azo dyes from aqueous environments is evaluated using the heterogeneous sono-Fenton process. The effect of operating parameters on the efficiency of pollutant removal is investigated and optimized. The stability, recyclability and performance of the nanocatalyst in multiple cycles are studied. The results of this research can provide an effective and sustainable solution for the treatment of water contaminated with azo dyes.
