Adsorption behavior and mechanism of Mg/Fe layered double hydroxide with Fe3O4-carbon spheres on the removal of Pb(II) and Cu(II)
Abstract
Mg/Fe layered double hydroxide loaded with Magnetic(Fe3O4) carbon spheres (MCs@Mg/Fe-LDHs) was firstly synthesized by a facile in-situ co-precipitation method to remove Pb(II) and Cu(II) pollution. To search the adsorption mechanism, MCs@Mg/Fe-LDHs was characterized by XRD, FTIR, XPS, TEM, and BET. There may exist surface complexation, precipitation, isomorphic substitution and physical adsorption in MCs@Mg/Fe-LDHs. The combination of those four types of reactions/interactions of metal ions with composite could improve the removal of Pb(II) and Cu(II). And the surface complexation was the main factor leading to the difference maximum adsorption capacity of Pb(II) (3.66 mmol/g) and Cu(II) (5.33 mmol/g). The adsorption kinetics and adsorption thermodynamics of MCs@Mg/Fe-LDHs for Pb(II) and Cu(II) could be better described by pseudo-second-order model and Langmuir model, respectively. The adsorption reaction was a spontaneous and endothermic process. Moreover, there existed competitive effect between Pb(II) and Cu(II) on the co-adsorption by MCs@Mg/Fe-LDHs. And the selectivity adsorption order of MCs@Mg/Fe-LDHs is as follows: Cu(II) > Pb(II) > Zn(II) > Ni(II) > Cd(II). Besides, in the real river water, the MCs@Mg/Fe-LDHs also exhibited stable adsorption capacity for Pb(II). In general, the MCs@Mg/Fe-LDHs has the potential for purification of water contaminated by Pb(II) and Cu(II).

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.
