In this study, novel mixed matrix membranes (MMMs) were synthesised by adding metal organic frameworks (MOFs) (UiO-66 and UiO-66-NH 2 ) to pristine sulfonated polyethersulfone (PES). The differing synthetic method resulting in MMM where additives grafted the polymer, or formed a natural interface, allowing impact of these features be investigated. composite characterised FTIR, PXRD, water conta...

The recent development in oil and gas industry increases the production and consumption of oil. The enormous amount of oily wastewater produced is urged to be treated to prevent humanity and environment from being threatened. Membrane technology is an appealing alternative for oily wastewater treatment due to its design simplicity, energy efficiency and environmentally benign approach. In this ...

Agilent Captiva Premium PES syringe filters are evaluated and compared to other suppliers’ PES and PVDF syringe filters for the risk of losing protein during filtration. Captiva Premium PES syringe filters demonstrate low protein binding with excellent recovery for biological samples, especially for ‘sticky’ proteins at low concentrations. In addition, an assessment of filter extractables on LC...

In the production of polymeric membranes used in water treatment by non-solvent-induced phase separation (NIPS) method, materials membrane casting solution and interaction these greatly affect properties performance obtained membranes. this study, polyethersulfone (PES) are produced NIPS method using two different solvents, dimethyl sulfoxide (DMSO) N-methyl-2-pyrrolidone (NMP), polyvinylpyrrol...

BACKGROUND Improving the sieving characteristics of dialysis membranes enhances the clearance of low-molecular-weight (LMW) proteins and may have an impact on outcome in patients receiving haemodialysis. To approach this goal, a novel polyelectrolyte additive process was applied to a polyethersulphone (PES) membrane. METHODS Polyelectrolyte-modified PES was characterized in vitro by measuring...

Biofouling is one of the drawbacks restricting the industrial applications of membranes. In this study, different thicknesses of silver nanoparticles with proper adhesion were deposited on poly(vinylidenefluoride) (PVDF) and polyethersulfone (PES) surfaces by physical vapor deposition (PVD). The crystalline and structural properties of modified and pure membranes were investigated by carrying o...

Immobilization of enzymes is one of the most promising methods in enzyme performance enhancement, including stability, recovery, and reusability. However, investigation of suitable solid support in enzyme immobilization is still a scientific challenge. Polyethersulfone (PES) and aminated PES (PES-NH2) were successfully synthesized as novel materials for immobilization. Membranes with various po...

Abstract The increasing occurrence of steroidal hormone micropollutant in the aquatic environment and their associated consequences have caused serious environmental concerns globally. Adsorptive removal hormonal pollutants using polymeric membranes has been suggested but information on performance various conditions is lacking. In this study, we examined effect salinity polyethersulfone (PES) ...

This paper presents the development of water-permeable dialysis membranes that are suitable for an implantable microdialysis system that does not use dialysis fluid. We developed a microdialysis system integrating microfluidic channels and nanoporous filtering membranes made of polyethersulfone (PES), aiming at a fully implantable system that drastically improves the quality of life of patients...
