Abstract Scope |
Microspheres can overcome many drawbacks regarding fine powders and nanoparticles like poor dispersion in aqueous solutions, limited pH range and toxicity to the medium. This study focused on synthesis of Fe-doped TiO2 microspheres via a sustainable approach for water remediation. The properties of synthesized microspheres were investigated through chemical, physical and spectroscopy analysis. At the end, adsorption performance of samples was tested with an aqueous uranyl solution and results were obtained using ICP-OES. Microspheres exhibited spherical-like structure, with minor defects and absence of cracks confirmed through SEM analysis. FTIR spectroscopy identified vibrational modes of -OH and Ti-OH bonds, crucial for surface interactions, while XRD confirmed the anatase phase as the predominant crystalline structure. The highest Fe doped sample (5%500) presenting higher surface area of 130,6 m2 g-1, as well as found to be effective on removing uranyl ions from water. |
