Study on fabrication of Fe2O3/TiO2 composite from titanium slag and its application for Pb2+ removal in aqueous media
Keywords:
Titanium slag, Fe2O3/TiO2, Composite, Heavy metals, AdsorptionAbstract
In this study, the Fe2O3/TiO2 composite was fabricated by sulphation of titanium slag followed by calcination at 600 oC for 2 hours. The adsorption behaviour of the Fe2O3/TiO2 composite as adsorbent toward Pb2+ was investigated by carrying out batch adsorption. The adsorption isotherm process of Pb2+ adsorption was closely related to Freundlich model and the adsorption kinetics of adsorbent toward Pb2+ adsorption was found to be pseudo-second order. The adsorption of Fe2O3/TiO2 composite toward Pb2+ is highly effective with a maximum capacity of 82,64 mg/g at pH 7, and relatively fast. Therefore, this as-prepared Fe2O3/TiO2 composite could be promising and cost-effective adsorbent for effective removal of lead contaminant from aqueous environment.
