Low-pressure highly permeable polyester loose nanofiltration membranes tailored by natural carbohydrates for effective dye/salt fractionation

MXene-regulation polyamide membrane featuring with bubble-like nodule for efficient dye/salt separation and antifouling performance

“…[1][2][3] In addition, the traditional manufacturing process is labor-intensive, with high energy consumption and severe environmental pollution. 4,5 Therefore, it is imperative to develop an efficient platform for the purication of dyes. Nanoltration (NF) as a pressure-driven membrane ltration process has gained extensive attention in the le of purication due to its advantages of low energy consumption and environmental friendliness.…”

Humic Acid Modified Selective Nanofiltration Membrane for Efficient Separation of PFASs and Mineral Salts

“…Besides lowering monomer concentration at water/hexane interface, the HA on the HA modified substrate might also participate in the interfacial polymerization reaction. Some studies have confirmed the interfacial polymerization reaction between natural organic compounds and TMC, 52 which would result in possible exposure of functional groups of HA on the surface of NF membranes. The exposure of HA on/in PA layers can also contribute to the surface charge of NF-HA membranes.…”

Absolute film separation of dyes/salts and emulsions with a superhigh water permeance through graded nanofluidic channels

“…In recent years, the film separation technology has been developed significantly in wastewater treatment and purification due to its sustainability and efficient advantages. 5,6 Combined with advanced fabrication methods, e.g., electrostatic spinning, 7,8 chemical vapor deposition, 9,10 interface aggregation [11][12][13] and…”

“…5,6 Combined with advanced fabrication methods, e.g. , electrostatic spinning, 7,8 chemical vapor deposition, 9,10 interface aggregation 11–13 and layer-by-layer assembly, 14,15 a range of biopolymers, 16,17 ceramic 18,19 and inorganic nanomaterials 20,21 have been used to improve the water separation capability of these films. Furthermore, due to the size difference between dyes and salt ions, the regulation of film pores and the construction of fluid channels has become the focus of screening dyes and salts.…”
