Equilibrium Uptake, Sorption Dynamics, Process Development, and Column Operations for the Removal of Copper and Nickel from Aqueous Solution and Wastewater Using Activated Slag, a Low-Cost Adsorbent
Abstract
Activated slag developed from blast furnace waste material has been used for the removal of copper and nickel. The effects of particle size distribution, contact time, and surface loading of these metal ions on the adsorbent for their removal have been studied at the optimum pH (5.0 for Cu 2+ and 4.0 for Ni 2+ ). Kinetic studies were performed to decide the mechanistic steps of the process and to obtain the thermodynamic parameters. Sorption data have been correlated with both Langmuir and Freundlich adsorption models. Column operations were also performed in an attempt to simulate industrial conditions. The bed-depth-service-time (BDST) model has successfully been applied to the sorptive removal of nickel and copper. Some feasibility experiments have been performed with a goal to recover adsorbate and chemical regeneration of the spent columns without dismantling the same.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
