Lead and cadmium sorption mechanisms on magnetically modified biochars.
TL;DR: The results indicated that cation exchange (as a metal sorption mechanism) was strengthened after Fe oxide impregnation, which limited the desorbed amount of tested metals.

TL;DR: In this paper, the authors present a consistent dataset of surface complexation model parameters valid at 25°C and 1'bar that characterize the adsorption of selected divalent metals (Cd, Cu, Pb, Zn) onto environmentally relevant Fe(III) (oxyhydr)oxides, i.e., FeOOH and Fe2O3 polymorphs (goethite, hematite, lepidocrocite, maghemite), at varying metal concentrations and ionic strengths.

TL;DR: The coupled SCM and spectroscopic approach is thus useful for investigating individual minerals responsible for Cr(VI) retention in soils, and improving the handling and remediation processes.

Sorption mechanisms of arsenate on Mg-Fe layered double hydroxides: A combination of adsorption modeling and solid state analysis.
TL;DR: This work proposes coupling surface complexation modeling with various spectroscopic techniques to investigate the adsorption mechanism of As(V) on Mg-Fe LDH or other sorbents, and presents a powerful approach for investigating this mechanism.

Highly effective Zn(II) and Pb(II) removal from aqueous solutions using Mg-Fe layered double hydroxides: Comprehensive adsorption modeling coupled with solid state analyses
TL;DR: In this article, a comprehensive mechanistic/modeling approach was proposed to describe the mechanism of metal ions binding on layered double hydroxides in contaminated waters, and the results indicated that these layered double hydrides are highly effective sorbents for metal ions from aqueous solutions.
