Water contamination caused by heavy metals, nutrients, and organic pollutants of varying particle sizes originating from domestic and industrial processes poses a significant global challenge. There is a growing concern, particularly regarding the presence of heavy metals in freshwater sources, as they can be toxic even at low concentrations, posing risks to human health and the… Continue reading Novel eco-friendly polylactic acid nanocomposite integrated membrane system for sustainable wastewater treatment: Performance evaluation and antifouling analysis
This paper aims to establish a new sustainable membrane with antifouling properties by developing a structured porous membrane with a honeycomb-like surface fabricated by blending polymers and additives via immersion precipitation and using a thermally induced phase inversion method coupled with exposure time to vapor. The hydrophilic properties, surface charge, and pore size of the membrane were… Continue reading Fabrication of a polyethersulfone/polyethyleneimine porous membrane for sustainable separation of proteins in water media
To enhance the green polylactic acid (PLA) membrane’s efficiency for removing organic materials, self-assembled functionalized graphene oxide carboxylic multi-walled carbon nanotubes (f-GO/MWCNTs-COOH) was incorporated into the membrane matrix followed by immersion precipitation. The successful formation of the negatively charged f-GO/MWCNTs-COOH nanohybrid was verified by scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FT-IR), X-ray diffraction (XRD) and zeta potential analyzer. The effect of… Continue reading High-performance f-GO/MWCNTs-COOH nanohybrid-based polylactic acid mixed matrix membrane for wastewater treatment
Graphene oxide and multi-walled carbon nanotubes have recently attracted attention, as they have proved to have potential in various applications. Therefore, in this study, a positively charged functionalized multi-walled carbon nanotubes (f-MWCNT)-graphene oxide (GO) composite was prepared by the electrostatic attraction approach, as they are oppositely charged, to test for its potential in wastewater treatment… Continue reading Self-assembled Positively Charged MWCNT-GO Composites for Wastewater Treatment
The integration of nanoparticles in wastewater treatment technologies has become an attractive topic to improve the membrane’s hydrophilicity, which is a vital membrane property needed for the efficient removal of contaminants. Functionalized graphene oxide (FGO) and oxidized multi-walled carbon nanotubes were used to synthesize FGO/MWCNT-COOH nanocomposite. The components of the nanocomposite were characterized through thermogravimetric… Continue reading Self-assembled Negatively Charged GO-MWCNT Composite for Wastewater Filtration
Despite significant progress in the field of biosensing, the impact of electric field on biosensor detection capability and the feasibility of the biosensor application in wastewater has yet to be investigated. The objective of this study was to develop a low-cost, highly sensitive, and selective reduced graphene oxide (rGO)-based biosensor. The constructed biosensor consists of… Continue reading Optimization of an rGO-based biosensor for the sensitive detection of bovine serum albumin: Effect of electric field on detection capability
Organic ligands have great potential to modulate the structure of iron oxides mineral in the natural environment and affect those minerals’ adsorption performances for arsenic species. This study was designed to examine the adsorption potential of goethite quantum dots impregnated graphene oxide hybrids (α-FeOOH QDs@GO) obtained through the consecutive modulation of β-FeOOH with organic ligands… Continue reading α-FeOOH quantum dots impregnated graphene oxide hybrids enhanced arsenic adsorption: The mediation role of environmental organic ligands
