    Application of Powdered Building Waste in Adsorption Technologies

  • Original language description

    Two powdered wastes originating in building materials production (waste brick dust (WBD) from the production of ceramic blocks and concrete slurry waste (CSW) from prestressed poles production used also in Fe-modified form (CSWFe)) were studied as potential adsorbents of ecologically risk cations (Cd2+, Pb2+) and anions (AsV as AsO43- and CrVI as CrO42-) from contaminated waters. The WBD indicated very good adsorption selectivity for Cd2+, Pb2+ and AsV at a high adsorption efficiency (90%), and worse parameters for CrVI adsorption (30% adsorption efficiency). The sorbent consumption was low (70 – 100 g per 1 g of contaminant) for cations (Cd2+, Pb2+) and more than four times higher for AsV. The adsorption of CrVI on WBD was ineffective. The adsorption of cations (Pb2+ and Cd2+) on CSW and anions (AsO43- and CrO42-) on CSWFe ran in the same manner as on WBD. Fe-modification of CSW to CSWFe increased its adsorption efficiency to anions by 15. – 20%. The cations (Pb2+, Cd2+) were adsorbed almost quantitatively (≈100%) on the initial CSW at the sorbent consumption of 10 – 120 g per 1 g of contaminant. The adsorption of anions (AsV, CrVI) on CSWFe reached ˃95% for AsV and 40-60% for CrVI, at the sorbent consumption of 80 – 200 g per 1 g of contaminant.
