Adsorptive removal of copper and cadmium ions using fly ash resulting from CFBC technology
Tomasz Kalak , Ryszard Cierpiszewski
AbstractFly ash was examined for the removal efficiency of Cu(II) an Cd(II) ions from water in batch experiments. This is industrial waste generated from the combustion of sewage sludge using the circulating fluidized bed combustion (CFBC) technology. The material was characterized using several methods, such as fraction analysis, particle size distribution, bulk density, composition, morphology, thermal analysis, the SEM-EDS, BET, BJH and FT-IR method. The influence of initial concentration, pH and contact time was conducted. The experiments demonstrated that this material had binding properties with respect to both these heavy metals. However, greater process efficiency was observed for cadmium than for copper. To conclude, the fly ash obtained in the combustion of sewage sludge is a promising low cost adsorbent for the effective recovery of copper and cadmium from industrial effluents.
