Summary: In this study, Fe(III) complexed polydopamine modified Mg/Al layered double hydroxides composite material (LDHs@PDA-Fe(III)) was prepared and used for the removal of Cr(VI) in aqueous solution. LDHs@PDA-Fe(III) showed excellent adsorption capacity and stability, which was confirmed through characterization analysis and adsorption experiments. The adsorption of Cr(VI) by LDHs@PDA-Fe(III) was found to be the result of the synergistic effect of multiple adsorption mechanisms. Therefore, LDHs@PDA-Fe(III) is an ideal adsorbent for removing Cr(VI) from aqueous solutions.

Summary: Up to 90% of glyphosate was efficiently removed by a 2:1 Mg2Al-layered double oxide (LDO) at pH 10 in 40 minutes. The adsorption kinetics followed a pseudo-second-order law, and the adsorption isotherms were of type L. The Langmuir model best described the experimental data, revealing the maximum adsorption capacity of glyphosate at 25 degrees C. Furthermore, the study investigated the interaction of glyphosate with LDO surface and the influence of different anionic species on glyphosate removal.

Summary: The Mg/Al layered double hydroxides-mordenite nanocomposite (LDH@mordenite) was prepared to improve the removal efficiency of Cr(VI) and Pb(II) through in-situ synthesis. The formation of a core-shell structure (mordenite core-LDH shell) enhanced the removal efficiency of Cr(VI) and Pb(II). The highest removal efficiency for both metals was achieved with an LDH content of 30% at pH 5.0. The adsorption kinetics of Cr(VI) and Pb(II) on LDH@mordenite followed the pseudo-second-order model. The Langmuir model provided the best fit for the isotherms of the adsorption process. The maximum adsorption capacity at 25 degrees Celsius was calculated to be 54.80 mg/g for Cr(VI) and 67.91 mg/g for Pb(II). The adsorption of Cr(VI) and Pb(II) onto LDH@mordenite was found to be endothermic and spontaneous based on thermodynamic analysis. The adsorption mechanism involved interactions between the ions and one or two adsorption sites on the adsorbent.

Summary: This study evaluated the performance of a composite material combining natural zeolite and Mg/Al LDH in the adsorption of ammonium from aqueous solutions. The results showed that the Mg/Al LDH-zeolite composite had higher adsorption capacity and heterogeneity. The optimal conditions for NH4+ adsorption were a solution pH of 8.0, a reaction time of 60 min, and an initial ammonium concentration of 40 mg/L. The maximum adsorption capacity of Mg/Al LDH-zeolite was 17.81 mg/g with an NH4+ removal efficiency of 89.03%.

A millimeter-sized nanocomposite, MgAl-201, was developed by impregnating Mg/Al LDH nanosheets into a polystyrene anion exchanger. MgAl-201 exhibited excellent adsorption performance and chemical stability in a wide pH range. It showed great potential for phosphate removal from neutral contaminated waters and achieved a treatable volume 8 times that of traditional anion exchangers.

Summary: A series of novel layered double hydroxides (Mg-Fe-Ti-LDHs) containing Mg2+, Fe3+ and Ti4+ were prepared and their adsorption performance on vanadate in aqueous solution was investigated. The results showed that the introduction of Ti4+ into the LDHs materials increased the vanadate adsorption efficiency. The adsorption capacity was also influenced by the anion intercalated layers, with Cl- intercalation showing higher removal compared to CO32-. The pH of the solution and coexisting ions also had significant effects on vanadate adsorption.
