dc.description.abstractThe aim of this study is to evaluate the possibilities for improving the adsorption capacity of blast furnace slag in processes for removal of heavy metal ions from aqueous media. Three samples of slag have been prepared by heating of granulated blast furnace slag. The initial slag and thermally treated slag samples have been characterized using X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), scanning electron microscope (SEM) and BET analysis. It has been found that the main crystalline phase of the analyzed slag samples is melilite. Merwinite and pseudowollastonite have been also identified. The Pb(II) adsorption isotherms have been obtained under bath conditions. All samples demonstrate a good Pb(II) removal ability. The equilibrium adsorption data are described by the Langmuir model. The highest Pb(II) adsorption capacity has been achieved by the blast furnace sample treated at 860 °C. The obtained results suggest that it is possible to improve the adsorption properties of blast furnace slag and slag based materials, by control of the phase composition.
