Use of waste ceramics in adsorption technologies
Original language description
Waste brick dust (WBD) was tested as a potential sorbent of cationic and anionic contaminants, including radioactive residues. For adsorption experiments, model water solutions of highly toxic and/or ecologically harmful cations (Cd, Pb, Cs) and anions (As, Sb, Cr, U) were selected. The adsorption of Cd2 + and Pb2 + on WBD was most effective (> 95%) at a very low sorbent dosage (up to 6 g L? 1). In terms of anionic contaminants, UVI was adsorbed as cationic complex particles [(UO2)n(OH)2n ? 1]+ almost quantitatively (> 95%) at a sorbent dosage of 3 g L? 1. The effective adsorption of AsV (> 90%) occurred at around a dosage of 15 g L? 1. The adsorption of Cs+, CrVI and AsIII on WBD was almost ineffective. Except for Cs+ and CrVI, all investigated ions were adsorbed according to the Langmuir isotherm model, at the theoretical adsorption capacities Qt ? approximately 0.1 mmol g? 1 for Cd2 +, Pb2 + and UVI, and approximately. 0.04 for AsV and AsIII. The leachability of toxic particles from saturated WBD was very low for selectively adsorbed particles (? 0.01?0.08% wt.) and their stability decreased in the order: Pb2 + ? Cd2 + > UVI > AsV > AsIII ? Cs+ ? CrVI. The approximate consumption of WBD per gram of toxic element was found to be about ? 60 g for Pb2 + and UVI, ? 100 g for Cd2 + and > 400 g for AsV. ? 2016 Elsevier B.V.
