The luffa sponge cellulose was extracted through a series of chemical treatments, including alkaline hydrolysis and bleaching, to remove non-cellulosic components. The purified cellulose was subsequently functionalized with Fe₃O₄ nanoparticles using an in-situ co-precipitation method under a nitrogen atmosphere to prevent oxidation. The resulting material was characterized using Fourier Transform Infrared Spectroscopy (FTIR), X-ray Diffraction (XRD), and Ultraviolet-Visible (UV-Vis) spectroscopy to confirm the structural, chemical, and optical modifications. The FTIR analysis confirmed the successful removal of hemicellulose and lignin, with new absorption peaks indicating Fe₃O₄ incorporation. XRD results demonstrated the presence of characteristic Fe₃O₄ diffraction peaks, confirming the formation of magnetic cellulose. UV-Vis spectroscopy further validated the structural changes, showing enhanced absorption in the 300–450 nm range due to Fe₃O₄ charge transfer transitions. The developed magnetic cellulose exhibited improved structural integrity, high crystallinity, and excellent functional properties, making it suitable for sustainable applications. This research contributes to the advancement of green synthesis methodologies and supports the circular economy by utilizing natural, biodegradable materials for functionalized nanocomposites. Future research should explore its scalability, reusability, and practical implementation in industrial applications such as wastewater treatment, heavy metal adsorption, and catalytic processes. The study highlights the potential of bio-based magnetic materials as a viable alternative to synthetic adsorbents, reinforcing the need for eco-friendly material innovations.
