Preparation of acid-resistant nanofiltration membrane with dually charged separation layer for enhanced salts removal

Yang Cao et al.

Summary: Acid-resistant nanofiltration (NF) membrane with precise ionic separation performance and high permeability for acidic wastewater reuse is important. The study dissects the two-layer reverse interfacial polymerization (r-IP) process for preparing high-performance acid-resistant membrane by investigating monomer reactions and phase interface properties. By changing monomer compositions and concentrations, the relationship between monomer reaction and membrane performance is elucidated. The use of aqueous additives of ethanol and glycerol improves the membrane surface properties and permselectivity.

Li+/Mg2+separation by membrane separation: The role of the compensatory effect

Fang Xu et al.

Summary: By studying nanopores in covalent organic frameworks, it is found that compensatory effect of pore-wall groups on ionic hydration plays a significant role in lithium-magnesium separation; meanwhile, moderately-electropositive nanopores can enhance separation factor and lithium ion permeation simultaneously. The balanced ratio of hydrophilic and positively-charged groups on pore walls is crucial for improving lithium-magnesium separation efficiency.

Constructing a selective blocked-nanolayer on nanofiltration membrane via surface-charge inversion for promoting Li plus permselectivity over Mg2+

Dan Lu et al.

Summary: A surface charge-inversion strategy was developed to construct a selective positive-nanolayer on nanofiltration membranes surface for selective separation of lithium ions, addressing the low lithium selectivity and complicated preparation issues. This strategy enhances the Donnan exclusion and size sieving capability for Mg2+ ions, achieving a high separation factor and anti-fouling performance.

A Nano-Heterogeneous Membrane for Efficient Separation of Lithium from High Magnesium/Lithium Ratio Brine

Huawen Peng et al.

Summary: A new strategy for preparing positively charged nanofiltration membranes has been reported, which shows ultrapermeable and selective separation of lithium ions from concentrated magnesium/lithium mixtures. The modification of the membranes with a new electrolyte monomer improves water permeance and stability in continuous nanofiltration. High lithium flux has been achieved at 6 bar operation pressure.

Polyamide membrane with nanocluster assembly structure for desalination

Shuhao Wang et al.

Summary: This study deconstructs the kinetic pathways of interfacial polymerization (IP) to probe the structure of polyamide (PA) nanofilm, demonstrating that the structure can be controlled by adjusting the monomers’ stoichiometric ratio at the new reaction interface. The resulting nodules with controlled size and surface characteristics offer tunable water-salt transport properties. These insights potentially guide the production of high-performance polyamide-based thin-film composite membranes.
