In recent years, the environmental pollution caused by micro/nanoplastics (MNPs) has increased. As a result of their negative impact on human health and the environment, MNPs have emerged as new scientific challenges. However, there are still some inconclusive findings. In this perspective, we analyze the traditional membrane performance that is thought to be applicable for… Continue reading Electrospun nanofiber membranes for the control of micro/nanoplastics in the environment
The continued use of non-biodegradable polymeric-based membranes for water purification has led to an unsustainable accumulation of waste at disposal, resulting in various environmental problems. In this study, eco-friendly asymmetric ultrafiltration (UF) membranes were fabricated from polylactic acid (PLA) with different polymer concentrations using the phase inversion method. The fabricated membranes were characterized using Fourier… Continue reading Asymmetrical ultrafiltration membranes based on polylactic acid for the removal of organic substances from wastewater
Polylactides are a prominent class of biocompatible and biodegradable polymers that can be used to fabricate membranes for wastewater treatment. Excessive nutrient (phosphorus and nitrogen) concentrations in water bodies are a serious concern that has resulted in widespread health problems and potable water shortages. In this study, ultrafiltration (UF) membranes were prepared from polylactic acid… Continue reading Development of green polylactic acid asymmetric ultrafiltration membranes for nutrient removal
This study focused on the surface modification of commercial TiO2 membranes with Fe3O4 decorated silver (Ag) nanoparticles (Fe3O4–Ag) via chemical attachment. Firstly, the Ag concentration on Fe3O4 was optimized, and different composites were prepared and characterized. Secondly, the optimal composite was used to prepare novel TiO2/Fe3O4–Ag ceramic membranes via surface coating through tetraethyl orthosilicate (TEOS)… Continue reading TiO2 ceramic membrane decorated with Fe3O4–Ag composite nanoparticles for produced water treatment
This research aimed at synthesizing polyethersulfone/α-zirconium phosphate (PES/ α-ZrP) flat-sheet nanocomposite ultrafiltration (UF) membranes. The impact of α-ZrP nanoparticle (NP) addition on the morphology, functionalities, hydrophilicity, and surface charge of the membrane, among others, were investigated. Different concentrations of α-ZrP NPs (0.25, 0.50, 0.75, and 1.00 wt.%) were tested. Membranes surface morphology was investigated by… Continue reading Development of Polyethersulfone/α-Zirconium phosphate (PES/α-ZrP) flat-sheet nanocomposite ultrafiltration membranes
