The world market for CO2/CH4 separation using membrane technology is getting bigger and polysulfone (PSf) is one of the most widely investigated polymer membrane materials. However, the existing PSf membranes performances are insufficient to fully exploit these opportunities. Therefore, modification that would produce membrane that fit the needs of target separation performances is a main issue...

In this study, polymer composite membranes comprising carbon nanotube (CNT), polysulfone (PSF) and polyvinyl alcohol (PVA) were synthesized via the phase inversion method and used to remove phenol from the phenol-containing wastewater. The fabricated membranes were reinforced with the functionalized carbon nanotubes (fCNTs) and coated with PVA to enhance their mechanical strength and anti-fouli...

Membrane separation is known as an efficient technique for the oily wastewater treatment. Therefore, in the present study, sulfonated poly (ether ether ketone) (SPEEK) was introduced into the polysulfone (PSF) solution in order to enhance the hydrophilicity and the membrane structure for the oil–water separation. The hollow fiber membranes were fabricated via a phase-inversion process. The memb...

   In this research, the classical phase inversion method was used to produce the polysulfone (PSF) membrane by using three different solvents: N, N-dimethylformamide (DMF), chloroform (CHCL3) and tetrahydrofuran (THF). Furthermore, different concentrations of functionalized multi – walled carbon nanotubes (MWCNTs) were added to PSF membranes by the classical phase inversion method...

Polyacrylonitrile-co-sodium methallylsulfonate copolymer (AN69) and polysulfone (PSf) synthetic membranes were prepared and used for the removal of methylene blue (MB) from water. Atomic Force Microscopy (AFM), Ionic exchange capacity (IEC), and Swelling ratio (Sr) were employed to determine the membrane characteristics. pH, membrane composition and initial dye concentration were used for t...

Lignocellulose nanofibrils (LCN) and cellulose nanofibrils (CNF) are popular nanometer additives to improve mechanical properties and hydrophilic abilities; moreover, lignocellulose has potential as a natural adhesion promoter in fiber-reinforced composites. LCN and CNF were blended into polysulfone (PSF) to prepare ultrafiltration membranes via the phase inversion method. These additives were ...

Excessive nutrient contents in water bodies renders eutrophication and causes undesired structural changes to the environment. One of the most straightforward strategies to address eutrophication issue is through the removal of nutrients such as phosphate ions from the water sources. A combination of membrane fltration and adsorption process is an attractive alternative...

Large quantities of wastewater are generated by the petroleum refining process. Micron-scale emulsion droplets and submicron difficult to remove from oil-refined wastewater, addressing these issues has been a major challenge for researchers. Membrane technology is widely used in water treatment because it very selective effective filtration his research focuses on oil refinery using polysulfone...

Porous low-pressure membranes have been used as active in water treatment and support for thin-film composite desalination gas separation applications. In this article, microfiltration polysulfone (PSf)mixed-matrix (MMM) containing amine-functionalized graphene oxide (GO-NH2) were fabricated via a phase inversion process characterized using XPS, SEM, AFM, DMA, XRD, contact angle measurements. T...

Hydraulic permeability and molecular weight cutoff (MWCO) performance tuning of polysulfone (PSf) ultrafiltration (UF) membrane was attained via surface modification with a tethered layer poly(acrylic acid) (PAA). Surface nano-structured (SNS) PAA synthesized onto base PSf UF membranes by atmospheric pressure plasma (APP) activation followed graft polymerization (GP) acrylic acid (AA). Through ...
