The use of electrospun nanofibrous membranes for the treatment of dyehouse effluent is drawing attention because of their high surface area, and dye adsorption capability. In this work, nanofibrous membranes of S-sulfonated wool keratin protein/poly(vinyl alcohol) or PVA were prepared by electrospinning, and their effectiveness as an adsorbent for the removal of cationic methylene blue (MB) dye… Continue reading Separation of cationic methylene blue dye from its aqueous solution by S-sulfonated wool keratin-based sustainable electrospun nanofibrous membrane biosorbent
This work provides a brief overview of the application of Sewage Sludge-Derived Biochar (SSBC) for the removal of micropollutants from aqueous solutions and wastewater. A particular emphasis is placed on the adsorption efficiency of SSBC regarding the Priority Substances defined under the scope of the EU Water Framework Directive.
Industrial and municipal wastewater treatment has the potential of providing considerable quantities of freshwater for different purposes. Prior to its usage, heavy metal ions elimination from treated wastewater must be ensured to evade their toxic and severe impacts on the water ecosystem and humans. For this purpose, graphene oxide (GO)/manganese oxide (MnO2) nanocomposite was prepared… Continue reading Investigation of Graphene Oxide (GO)-Manganese Oxide (MnO2) Nanocomposite in Metal Ions Adsorption from Wastewater
As an edible oil, palm oil is also safe and reliable in dyeing, and the residual palm oil after dyeing can be recycled and used continuously, which is green and environmentally friendly and has great research prospects. In this research, raw ramie yarn, used for traditional grass cloth, was dyed in a palm oil medium… Continue reading Adsorption Behaviour of Reactive Blue 194 on Raw Ramie Yarn in Palm Oil and Water Media
The ability of organic ligands to change the structure of metal-organic frameworks (MOFs) in nature and influence their adsorption efficiency for arsenic species is enormous. The current work was designed to investigate the adsorption performance of cerium-based MOFs with tunable structures through the use of organic ligands (Ce-MOF-66 and Ce-MOF-808) towards arsenic species from water.… Continue reading Tuning the structure of cerium-based metal-organic frameworks for efficient removal of arsenic species: The role of organic ligands
In the present work, polyethersulfone/polyacrylonitrile (PES/PAN) blended electrospun nanofiber-based membrane was fabricated and applied for an environmentally friendly protocol for removing methylene blue (MB) from aqueous solutions. The structural integrity of the newly synthesized membrane was investigated by SEM, FTIR, TGA and XRD, demonstrating the successful integration of the PES/PAN blended nanofibers membrane. SEM results… Continue reading Fabrication of polyethersulfone/polyacrylonitrile electrospun nanofiber membrane for food industry wastewater treatment
Using an environmentally friendly approach for eliminating methylene blue from an aqueous solution, the authors developed a unique electrospun nanofiber membrane made of a combination of polyethersulfone and hydroxypropyl cellulose (PES/HPC). SEM results confirmed the formation of a uniformly sized nanofiber membrane with an ultrathin diameter of 168.5 nm (for PES/HPC) and 261.5 nm (for… Continue reading One-Step Fabrication of Novel Polyethersulfone-Based Composite Electrospun Nanofiber Membranes for Food Industry Wastewater Treatment
