Shrnutí:Title screen
This study presents in situ synthesis of a nanocomposite of Fe3O4 nanoparticles directly grown on the surface of two-dimensional (2D) reduced-graphene-oxide nanosheets. The morphology, structure, chemical and phase composition, and magnetic properties of the developed nanocomposite were investigated. The nanocomposite, when mixed with sand, effectively addressed the challenge of arsenic removal from water on a fixed-bed column with sorption capacity 8.40 and 8.96 mg/g for arsenic concentrations 0.1 and 10 mg/L, respectively. This performance is superior to that reported in the literature for alternative iron-containing arsenic sorbents. The sorption isotherms were modelled using the Thomas model and the R-square value was around 0.9, reflecting good correlation between the experimental data and isotherm model. The As3+ sorption process caused no significant changes in structure, phase composition, and magnetic properties of the nanocomposite, implying its good potential for reuse and its economic viability for applications related to arsenic removal from contaminated water
