Summary: MoS2@Kaolin composite material shows efficient, rapid, and highly selective adsorption of Pb(II). The adsorption process follows the Langmuir isotherm model with a maximum adsorption capacity of 280.39 mg/g. Additionally, the adsorption kinetics of MoS2@Kaolin to Pb(II) fits well with the pseudo-second-order kinetics models.

Summary: A magnetic mesoporous nanoadsorbent Fe3O4@SBA-15-Gd has been prepared through a multistep fabrication process for effectively removing Cu(II) and Pb(II) heavy metals from aqueous solutions. The adsorbent showed remarkable adsorption capacity and selectivity towards Cu(II) and Pb(II) due to the formation of chelating groups on the support material.

Summary: The nature and amount of hydrogen species adsorbed on MoS2-based catalysts were studied by inelastic neutron scattering (INS) under various preparation and treatment conditions. The major hydrogen species adsorbed on MoS2 catalysts was found to be similar regardless of preparation or promotion conditions, mainly originating from the vibrations of dangling -SH groups linked to six-coordinated Mo atoms at the M edges of MoS2 slabs.

Summary: This study demonstrates the synthesis of a partially reduced graphene oxide-nano-molybdenum disulfide composite (prGO-MoS2) with ultra-fast Pb(II) removal capability. The prGO-MoS2 exhibits high removal efficiency and selectivity, with the ability to decrease the concentration of Pb(II) from 10,000 ppb to 0.8642 ppb within a short time. It has the fastest removal speed and the second-highest adsorption capacity among reported materials for Pb(II) removal.

Summary: In this study, a novel amino-functionalized Fe3O4-MnO2-SiO2-NH2 adsorbent material was prepared and shown to have high selectivity for removing Pb(II) in both mixed solution and single-solute solution. The material exhibited a core-shell structure with Fe3O4 as the core, SiO2 as the outer shell, and MnO2 located between them. The adsorption capacity of the material was greatly affected by the initial pH value. The kinetic and equilibrium data were well described by the pseudo-second-order model and Freundlich isotherm, respectively. The material showed excellent adsorption and desorption efficiencies over multiple cycles.

Summary: The engineering of macroscopic architectures by loading MoS2 nanosheets onto larger framework materials is an efficient strategy to overcome the limitations of nanosized MoS2-based adsorbents for Pb(II) removal. A practical and efficient nanocomposite, MoS2/PDA/MPS, was prepared by coating MoS2 nanoflowers onto micron-sized polystyrene beads (MPS) via a strong adhesive polydopamine (PDA) interlayer. The nanocomposite exhibited fast adsorption kinetics, high adsorption capacity, and stability, making it suitable for the remediation of lead-containing wastewater.

Summary: The efficiency of Fe3O4-MoS2 nanosheets synthesized through hydrothermal process and its fabrication with chitosan (Fe3O4-MoS2@CS) in removing Cr(VI) and ciprofloxacin (CIP) from simulated wastewater was evaluated. The nanohybrid materials were characterized and their selectivity for different metal ions was studied. Fe3O4-MoS2@CS showed high selectivity for Cr(VI) and enhanced removal efficiency for CIP. The adsorption process was influenced by pH and followed the Langmuir isotherm model.

Summary: In this study, magnetic nanoparticles (Fe3O4 NPs) functionalized with silica (SiO2) and 2, 3-dimercaptosuccinic acid (DMSA) were synthesized. The prepared DMSA@SiO2@Fe3O4 nanocomposite showed excellent performance in removing Cu2+ from aqueous solutions, with good dispersibility, stability, and magnetization. By using Box-Behnken design and response surface methodology, the optimal conditions for Cu2+ removal were determined, and it was found that the adsorption process followed pseudo-first-order kinetics and Langmuir isotherm. This design method can be applied to various environmental applications.

Summary: CS-ZL/ZrO/Fe3O4, synthesized by a crosslinking method, is a novel adsorbent for the removal of phosphate (PO43-) from water, increasing the stability of chitosan and exhibiting good mechanical stability. pH, dosage, and time were found to be the three most important factors for PO43- removal. The adsorbent had no significant effect on the removal of coexisting ions. After adsorption, PO43- can be easily released by 1 M NaOH and can be used for three cycles.

Summary: Fe3O4-Ti3C2Tx (FeMX) adsorbent with different doping amounts of Fe3O4 was prepared by one-step hydrothermal method to improve the chemical stability and ion adsorption capacity of Ti3C2Tx. The maximum theoretical Pb(II) adsorption capacity of FeMX adsorbent was found to be 210.54 mg/g. The adsorption mechanism revealed that Fe3O4 nanoparticles were evenly dispersed and intercalated between Ti3C2Tx nanosheets, enhancing the specific surface area and layer spacing of Ti3C2Tx nanosheets and improving the ability to remove Pb(II). This study provides a promising route for developing MXene matrix composites with excellent heavy metal ion adsorption properties.
