Abstract
The increasing presence of textile pollutants, pathogens, and free radicals poses significant concerns for the depletion of aquatic resources. This study proposes the use of tin oxide nanoparticles (SnO2 NPs) synthesized using Tectona grandis leaf extract as a sustainable approach to address these pressing environmental issues. To achieve sustainable growth, it is crucial to evaluate the optimal parameters necessary for effectively mitigating toxic pollutants discharged from textile wastewater. This research systematically investigates the influence of catalyst concentration, dye concentration, and pH on the photocatalytic performance of the prepared SnO2 nanoparticles. The optimized parameters resulted in remarkable degradation efficiencies of approximately 98.71 % for Congo Red (CR) dye and 98.01 % for Rhodamine B (RhB). The cyclic stability of the prepared catalyst also demonstrated notable results, with minimal degradation loss of 4.8 % for RhB dye and an extended loss for CR due to pH-related factors. Additionally, antimicrobial testing revealed maximum zones of inhibition of 18 mm and 20 mm against E. coli and S. aureus, respectively, while the nanoparticles exhibited significant antioxidant potential, with an activity of 89.78 %. Overall, this study highlights the physicochemical properties and multifunctional capabilities of SnO2 NPs, showcasing their potential for environmental and clinical applications in alignment with sustainable development goals.
