Summary: The harmful effects of aqueous metal pollutants and the benefits of recycling drive the need for wastewater treatment and metal recovery. Supported liquid membrane (SLM) separation is a potential energy-efficient technique for selectively recovering metal ions, but there is a need for improvement in transport rate and stability in order to enhance treatment capacity and SLM lifetime. Previous lab studies have shown metal removal efficiencies above 70% and mass transfer coefficients in the range of 10(-6) m/s, but there is variation in the reported stability of SLM for different setups tested. Recent research has explored the use of environmentally friendly chemicals in constructing SLMs. This review focuses on factors affecting selectivity, transport kinetics, and stability of SLMs, and discusses strategies for maturing SLM technology for industrial-scale treatment of metal-bearing wastewater.

Summary: A highly branched pillar[5]arene-based sensor (B-P[5]arene) containing multiple BODIPY units has been designed and synthesized. Systematical experiments show that B-P[5]arene exhibits high sensitivity and selectivity to both Sn (II) and Hg (II) in acetonitrile/water. Hg (II) ions quench the fluorescence intensity of B-P[5]arene, while Sn (II) causes a broader spectrum without any shifting in wavelength.

The fluorescence and antibacterial properties of UiO-66-Cel-Nap and ZIF-8-Cel-Nap materials were investigated, with ZIF-8-based materials exhibiting better antimicrobial properties. Materials containing Ag+ were found to be more effective against bacteria than those containing AgNPs, and ZIF-8-Cel-Nap-Ag+ was the most effective material with a significant antibacterial effect against E. coli at a MIC value of 0.0024 mg/mL.

Summary: In this study, PVDF-based anion-exchange membranes were designed to selectively separate nitrate from chloride. Experimental data showed that increasing the concentration of PVDF enhanced nitrate transport but also increased the membrane electrical resistance. The selectivity of nitrate was found to be independent of the membrane thickness and mainly driven by the increased affinity between the anion and the membrane.

Summary: This study focuses on the modification of a commercially available polyamide thin-film composite membrane with a zwitterionic material to enhance its fouling resistance. The modified membrane shows improved salt rejection and reduced permeability compared to the pristine membrane. Fouling tests demonstrate that the modified membrane has a lower fouling ratio and higher recovery ratio. The enhanced antifouling characteristics are attributed to the improved hydrophilicity resulting from the zwitterionic brushes and the salting-in effect.

Summary: To meet the huge demand for lithium resources, there is an urgent need to develop a new efficient technology for lithium recovery from salt-lake brines. In this study, a selective membrane capacitive deionization system is reported, which achieves high lithium recovery capacity and rate through the use of materials with efficient intercalated pseudo-capacitance and a high specific area porous carbon. The use of a modified thin-coated membrane allows for selective Li+ recovery, and adjusting the concentrations of Li+ and Mg2+ in the feed solution enables higher Li+/Mg2+ selectivity.
