Liposomes-assisted fabrication of high performance thin film composite nanofiltration membrane

, 2021
Conventional biomimetic membranes for desalination are mostly fabricated by incorporating water channels using self-assembled lipid or polymer vesicles as key platforms for protein or water channel reconstitution. Herein, we propose a thin film composite

Positively charged nanofiltration membranes for efficient Mg2+/Li+ separation from high Mg2+/Li+ ratio brine

Advanced Membranes, 2023
Nanofiltration has gained increasing attention in lithium extraction from salt lake brine with high Mg2+/Li+ ratio. However, conventional nanofiltration membranes with negatively charged surfaces suffer from low Mg2+/Li+ selectivity.

Tuning d-spacing of graphene oxide nanofiltration membrane for effective dye/salt separation

, 2022
The interlayer spacing (i.e., d-spacing) plays a crucial role in determining the selectivity and permeability of nanofiltration membranes. A high-throughput directional filtration can be achieved by designing and controlling the d-spacing. In this study,

Dichloroaniline retention by nanofiltration membranes

Water Research, 2005
This study evaluates the performance of two nanofiltration membranes in removing a herbicide: dichloroaniline. The membranes, one polyamide and one cellulose acetate, have a cut-off in the range 150-300 g/mol (manufacturers' data). The experiments were carried out with solutions of dichloroaniline in demineralized water, with concentrations from 1 to ...

Fabrication of polyamide hollow fiber nanofiltration membrane with intensified positive surface charge density via a secondary interfacial polymerization

, 2023
In this work, a positively charged hollow fiber nanofiltration (NF) membrane based on twice interfacial polymerization (IP) reactions was developed for water soften and heavy metal ions removal. The first IP reaction was conducted on the polyethersulfone
