Photocatalytic Removal of Crystal Violet Dye Utilizing Greenly Synthesized Iron Oxide Nanoparticles

The presence of synthetic industrial dyes in the environment poses significant risks to aquatic ecosystems, human health, and economies. This study aims synthesize iron oxide nanoparticles (IONPs) using a green method, analyze them physicochemical techniques, examine effectiveness with which they photocatalytically degrade crystal violet dye sunlight. Fourier transform infrared spectroscopy (FTIR) analysis revealed that biogenic IONPs showed UV peak at wavelength 241 nm, functional groups including phenols, alkynes, alkenes. X-ray diffraction (XRD) confirmed amorphous nature bioinspired IONPs. mean diameter was 49.63 ± 9.23 had surface charge −5.69 mV. efficiency synthesized removed evaluated under dark sunlight conditions. removal found be concentration time dependent, percentage 99.23% being achieved when were exposed for 210 min. also demonstrated antioxidant activity, relative IC50 value 64.31 µg/mL. In conclusion, offer viable environmentally friendly approach eradicating remediating contaminated environments ecosystems.
