Reuse of sustainable materials for xylenol orange dye and copper (II) ion ammoniacal removal.

摘要: Abstract Water pollution caused by heavy metals and organic compounds is an environmental problem with negative impact, making the restoration of water quality a priority. In this paper, adsorption xylenol orange dye (XO) on vitreous tuff mineral (VT) was studied. It established that capacity VT 45.17 mg/g. The removal carried out interactions between active sites surface material functional groups dye. solid waste obtained from process (VTXO) reused as adsorbent for Cu in form complex Cu-NH 3 because done ammoniacal medium. found new 33.09 mg/g. previous research, used to remove crystal violet (CV) instead XO. last (VTCV) also applied removal, order compare after two different kinds dyes. VTXO lower than VTCV (71.23 mg/g). both processes, kinetic well described chemical onto heterogeneous surface. equilibrium time XO 50 min 80 min . experimental design stated maximum reached when initial concentration 6400 mg/L solid-liquid ratio 10 g/L. system requires least amount counter flow batch. Finally, it possible estimate behavior higher scale. This research provides efficient economical alternative treat contaminated dyes cooper medium using same one other.
