Facile Fabrication of Fe2O3/TiO2 Composite from Titanium Slag as Adsorbent for As(V) Removal from Aqueous Media

Mixed metal oxide composites have been widely used as adsorbents for the removal of heavy ions from wastewater. In this work, Fe2O3/TiO2 composite was sustainably prepared via treatment titanium slag with a low-concentration sulfuric acid solution (20%) and As(V) aqueous solutions. The resulting products were characterized by X-ray diffraction (XRD), N2 adsorption−desorption, Fourier-transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), energy-dispersive (EDX). batch adsorption employed to investigate efficiency adsorbent toward As(V). Langmuir Freundlich isotherms plotted in order study process. on FeO3/TiO2 fitted well isotherm model, suggesting multilayer process an capacity 68.26 mg·g−1. kinetics demonstrated that behavior pseudo-second-order. With low-cost preparation high capacity, could be effective contaminated water sources. approach utilized research is viewed sustainable route creating proficient purification water.
