Ease Synthesis of Broccoli -Like Fe3O4 Nanostructures for Superior Removal of Eosin Yellow Dye

Due to its crucial function in environmental cleanup, superparamagnetic iron oxide nanoparticles continue to be the topic of intensive research in the present day. The elimination of textile effluent dye is the subject of the current investigation. Inverse spinel (Fe2O3. FeO) was produced as magnetic iron oxide (Fe3O4) nanoparticles using an unique precipitation approach that relied on the preparation of the particles without any calcination under oxygen gas. The iron sulfate solution was combined with an aqueous mixture of sodium hydroxide and sodium nitrate to create the Fe3O4 nanoparticles, both without and with the use of surfactant like cetramide as templates. FT-IR spectra showed that Fe-O octahedral and tetrahedral bindings at 744 cm-1 and 598 cm-1, respectively, indicated to form an inverse spinel particle. The X-ray diffraction (XRD) research explained that the mean crystal size of Fe3O4 nanoparticle increased from 8.5 nm for Fe3O4 nanoparticle to 22.53 nm for prepared Fe3O4 in presence of cetramide as a template. SEM found the produced shapes as spherical like brooklei. The thermodynamic analysis demonstrated that prepared Fe3O4 in the presence of cetramide underwent endothermic adsorption with chemisorption, while the magnetite prepared without using cetramide is exothermic with physisorption. The magnetite with cetramide a better fit for Freundlich model, and proved it chemisorption. The findings showed that Fe3O4 produced with cetramide is a better adsorbent for removing anionic dye and it is utilized to remove water contaminants.
