Abstract

The blast furnace sludge (BFS) is a waste material of pig iron production. The chemical and mineralogical composition of BFS was examined by Proton Induced X-ray Emission (PIXE) and X-ray Diffraction (XRD) methods. Surface area properties (specific surface area, average pore diameter, total pore volume) are determined by the Brunauer-Emmett-Teller (BET) and Barrett-Joyner-Halenda (BJH) method. The microscopic observation was conducted using a scanning electron microscopy (SEM method).
Chemical treatment of BFS was performed by adsorbed citric acid. Thermal treatment was done by heating at 700°C. The surface properties of the blast furnace sludge are compared to those obtained after treatment. The results have shown that this successfully performed experiment modified the surface of BFS as a potentially low-cost adsorbent.
