Photocatalytic Removal of Methylene Blue Dye from Aqueous Solutions Using Bismuth Oxide Nanoparticles: Optimization and Environmental Implications

This study investigates the photocatalytic removal of methylene blue dye using bismuth oxide nanoparticles. Optimal conditions achieved a ۹۰.۳۱% removal efficiency at a catalyst dosage of ۰.۲ g/L, pH ۳, and initial dye concentration of ۱۰ mg/L. Acidic conditions enhanced adsorption due to the catalyst's positive charge. The findings highlight the nanoparticles' potential for sustainable wastewater treatment and the importance of optimizing photocatalytic processes for environmental sustainability.
