TiO2-Zeolite Composite Modified Iron Nanoparticles for the Removal of Cr(VI) from Wastewater
Year: 2025
Type: article
Abstract: Zero valent iron (Fe0) particles are significant in wastewater treatment because of their high reactivity, rapid kinetics, magnetic characteristics, and eco-friendliness. The primary drawbacks of Fe0 nanoparticles are their rapid oxidation and aggregation. In this study, novel TiO2-zeolite composites with different percentages of TiO2 were prepared and applied for Fe0 stabilization. The TiO2-zeolite composite was synthesized using the sonication of components, subsequently employing the hydrothermal technique. Iron nanoparticles were included into the TiO2-zeolite composite using the wet impregnation method followed by liquid-phase reduction. For comparative study with TiO2-zeolite-Fe nanoparticles, TiO2-Fe and zeolite-Fe nanoparticles were also prepared. The characterization of TiO2 and zeolite modified Fe nanoparticles were done by XRD, HRTEM, EDAX, FTIR and UV-visible spectroscopic techniques. The study evaluated the efficiency of prepared TiO2-Fe, zeolite-Fe and TiO2-zeolite-Fe nanoparticles to remove Cr(VI) from wastewater.
