Elucidation of Interactions between Metal Ions and Ca Alginate-Based Ion-Exchange Resin by Spectroscopic Analysis and Modeling Simulation
Abstract
In this study, a cost-effective calcium alginate-based ion-exchange resin (CABIER) was employed for treatment of metal waste streams. pH, concentration, and presence of competitive metal ions played important roles in the removal. The X-ray photoelectron spectroscopy (XPS) and Fourier transform infrared spectroscopy (FT-IR) analysis indicated that the functional groups on the carbohydrate backbone (i.e., C−O−R and COO - 1 ) were responsible for the binding of metals. It was found that the lead abstraction was driven by the ion exchange between Ca 2+ and Pb 2+ . On the contrary, the Cu 2+ ion was stripped via both ion exchange with Ca 2+ and coordination of the other functional groups. A new mathematical model based on ion exchange (between metal and calcium) and elementary coordination (among metals and functional groups) reactions successfully described and predicted the metal removal under various conditions (e.g., pH, concentration, and existence of competitive metal ions). It was found from the modeling that metal binding follows a decreasing order of Pb 2+ > Cu 2+ > Ca 2+ .

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.
