Summary: In this study, [SnS4](4-) clusters and MgFe-based layered double hydroxide (LDH) were assembled to synthesize [SnS4](4-)/LDH composites, which showed excellent removal performance for mercury and arsenic. The composite effectively adsorbed the heavy metals by enlarging surface areas and creating a hierarchical pore channel, and dynamic analysis revealed different adsorption mechanisms. The pseudo-second-order kinetic model was found suitable for both Hg(II) and As(III) adsorption, with promising potential for mercury recycling from the spent materials.

Summary: The research highlights the preparation of a stable CaFe-LDH stabilizer with high efficiency in removing nickel ions and exhibits great potential in removing nickel ions from real electroplating wastewater. The isomorphous substitution of Ca2+ by Ni2+ in the laminate of LDH plays a key role in the mineralization process, transforming CaFe-LDH to NiCaFe-LDH, which shows improved electrocatalytic and photocatalytic activities. This work opens up a promising path for the removal of Ni2+ ions from wastewater and utilization of recycled nickel resources.

Summary: A simple and direct synthesis method of layered double hydroxides (LDHs) in wastewater was developed for the efficient removal of ciprofloxacin (CIP) and tetracycline (TC) contaminants. The LDHs structure was characterized and the removal of CIP/TC was investigated using different Mg/Al ratios and stepwise experiments. The CIP/TC molecules were sandwiched between the LDHs layers and the removal process was controlled by positive charges, resulting in more efficient utilization of the LDHs layer. The calculated average energies of CIP and TC under competitive adsorption were 18.68 and 16.68 J·mmol(-1), respectively.

Summary: Phosphorus pollution can cause both aquatic eutrophication and global phosphorus scarcity. Fe-based layered double hydroxides (LDHs) have been extensively studied for their high phosphorus adsorption and recovery. The composition of Fe-based LDHs is crucial in determining their adsorption performance. In this study, Zn/Fe LDH exhibited a much higher adsorption capacity than Mg/Fe LDH, and calcination significantly increased the adsorption capacity of Mg/Fe LDH. The phosphorus removal efficiency of Fe-based LDHs was high under acidic conditions but decreased with increasing pH, with Zn/Fe LDH showing weaker pH inhibition.

Summary: From an environmental and resource management perspective, it is preferable to recover and reuse heavy metal ions found in electroplating wastewater. The discharge of electroplating wastewater has caused serious environmental pollution and resource waste. Ca-based layered double hydroxides (LDHs) stabilizers are designed, which show a rapid, effective, and adequate capacity exceeding 400 mg/g against solutions of Cu2+, Zn2+, Co2+, and Ni2+ ions through an isomorphous substitution mechanism. The needs of plant development were met by the use of CaAl-LDH in soil remediation. While Cu resources can be recovered from the CuAl-LDH products by electrolysis, the final mineralization products from Ni2+ and Zn2+ ions showed exceptional performance in visible-light-induced photocatalytic reduction of CO2 with excellent selectivity (98.7% toward CO and CH4) and the removal of arsenite ions (99.97%). The results of this investigation revealed a feasible new approach to the removal, recycling, and reutilization of heavy metal ions.

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.

Summary: This study investigates the feasibility and mechanisms of a chemical-free nanobubble-based AOP for treating organic micropollutants in water. The results show that the oxygen nanobubble AOP has a significantly higher removal efficiency compared to air and nitrogen nanobubbles. The treatment performance is not affected by pH and the presence of ions. Higher initial concentrations of the micropollutant lead to slower treatment processes, but similar removal performance is achieved in the end. The presence of organic matter reduces the removal rate of the micropollutant. The results have practical feasibility for water and wastewater treatment.
