Synthesis of an iron-titanium-carbon composite from slag high in titanium for removing arsenic particles from drinking water

Abstract

The objective is to develop a novel iron-titanium-carbon composite using titanium-rich slag as a precursor material. This composite should demonstrate efficient arsenic removal capabilities for water-based treatments. The straightforward photochemical method is used to create a microporous iron-titanium/carbon composite by milling titanium-rich slag with activated carbon at room temperature. XRD, SEM, EDX, and N2 adsorption/desorption were used to describe it. This microstructure sorbent has excellent composition, surface area, and pore structure suitable enough to intake As(V) ions from drinking water at pH 6 with the adsorption capability of 86 mg/g. Among the many adsorption isotherm types examined, the Langmuir isotherm had the best fit with R2:0.9879. The intake of As(V) into the produced composite was most aptly stated by the Elovich model (R2:0.9899), according to the kinetic investigations. Given that, the synthesized micro-composite exhibits long-term stability and reproducibility over several regeneration cycles. Our findings displayed that the synthesized iron-titanium/carbon composite is effectively convenient for the elimination of As(V) with the effectiveness of recuperation of 95%.
