Abstract

This study investigates the potentials of magnetic iron oxide (Fe3O4) nano-particles as a photo catalyst for the removal of methylene blue dye from aqueous solutions under UV irradiation. It was synthesized through co-precipitation method and characterized using UV-Visible spectroscopy and scanning electron microscopy (SEM), revealing a band gap of 4.7 eV and a porous, irregular morphology conducive to photo catalysis under UV irradiation. Optimal photo catalytic conditions were determined as 0.5 g catalyst dose, 20–40 ppm initial dye concentration, 60 minutes contact time, and an alkaline pH of 12, achieving high degradation efficiency. Adsorption isotherm studies confirmed that the Langmuir model best fits the experimental data, indicating mono layer adsorption on a homogeneous surface. The magnetic separability of Fe3O4 nano particle enhances its practicality, offering an eco-friendly, reusable, and scalable solution for treating textile wastewater. These findings underscore the potential of Fe3O4 nano particles as a sustainable alternative for mitigating dye pollution, with implications for advancing nano material-based environmental remediation strategies.
