To achieve greater separation performance and antifouling properties in a thin-film composite (TFC) nanofiltration membrane, cellulose nanocrystals (CNCs) were incorporated into the polyamide layer of TFC membrane for first time. The results Fourier transform infrared spectroscopy X-ray photoelectron (XPS) confirmed successful formation CNC-polyamide layer. Surface characterization revealed differences morphologies CNC-TFC membranes compared with control (CNC-TFC-0). Streaming potential...
The inherent properties of hydrophilicity and mechanical strength cellulose nanocrystals (CNCs) make them a possible alternative to carbon nanotubes (CNTs) that may present fewer objections application water-treatment membranes. In this work, the CNCs CNTs nanocomposite poly(ether sulfone) (PES) membranes were characterized compared. Membrane pore geometry was analyzed by scanning electron microscopy (SEM). Overall porosity mean radius calculated based on wet-dry method. Results showed PES...
A high-performance nanofiltration (NF) membrane with simultaneously improved desalination and antifouling properties while maintaining regeneration ability is highly desirable in water treatment. Surface modification an effective approach to enhance the performance of NF membranes. In present study, a multifunctional thin-film composite (Fe-TFC) was fabricated via coating regenerable ferric ion-tannic acid (FeIII-TA) layer on nascent polyamide surface. The Fe-TFC exhibited enhanced...
An ordered mesoporous perovskite, La2CoMnO6−δ (MLCMO), was synthesized for the first time using a facile method of evaporation-induced self-assembly. The N2-sorption, scanning electron microscopy, and transmission microscopy measurements indicated that optimized MLCMO possessed high specific surface area (58.7 m2/g) uniformly (11.6 nm). exhibited superior catalytic performance in peroxymonosulfate (PMS) activation atrazine (ATZ) degradation. From comparison view, activity outperformed bulk...
Utilizing brackish water resources has imposed a high requirement on the design and construction of nanofiltration membranes. To overcome limitation salt concentration separation performance resulting from weakened Donnan effect, membrane with effect salt-responsive ion valves was developed by incorporating zwitterionic nanospheres into polyamide layer (PA-ZNs). The interaction between membranes at salinity revealed through combination analysis perspectives transport model, positron...
Water reuse is an effective way to solve the issues of current wastewater increments and water resource scarcity. Ultrafiltration, a promising method for reuse, has characteristics low energy consumption, easy operation, high adaptability coupling with other treatment processes. However, emerging organic contaminants (EOCs) in municipal cannot be effectively intercepted by ultrafiltration, which poses significant challenges effluent quality sustainability ultrafiltration process. Here, we...
