Abstract (english)
This study describes the use of blast furnace sludge (BFS) for the removal of toxic Ni(II) ions from a water system.Blast furnace sludge is a by-product and a waste material of the steelmaking industry. Chemical and mineralogical characteristics of BFS are determined by Proton Induced X-ray Emission and X-ray Diffraction methods.The surface area properties are determined by the Brunauer-Emmett-Teller method. The adsorption is investigated in a batch adsorption system in view of its kinetics and thermodynamics. The kinetic experiments show that the adsorption process follows a pseudo-second order model. The adsorption mechanism is investigated by intra-particle diffusion and Boyd-Reichenberg kinetic models. Thermodynamic parameters (activation free energy change, activation enthalpy change, and activation entropy change) reveal that the adsorption of Ni(II) on BFS is spontaneous, exothermic, and chemical in nature. The results suggest that BFS is an inexpensive and efficient adsorbent for the removal of Ni(II) ions from aqueous solutions.
