International need for water quality is placing a high demand on separation technology to develop advanced oxidative processes polyethersulfone (PES) membranes help improve purification. Therefore, VUV photo-oxidation with low pressure Ar plasma was studied the hydrophilicity of PES by flowing oxygen over surface during treatment. X-ray photoelectron spectroscopy (XPS) detected decrease in C at...

this paper reports on preparation of polyamide membrane with addition of silver nanoparticles (agnps). agnps act as antibacterial agents that are less susceptible to membrane’s biofouling by interfacial polymerization (ip) method. agnps was synthesized via green route which has been reported previously. attenuated total reflectance-fourier transform infrared spectroscopy (atr-ftir), field emiss...

in this study, a mixed matrix polyethersulfone/iron-nickel oxide nanoparticle nanofiltration membrane was prepared by the solution casting technique. polyvinylpyrrolidone was also used as a membrane pore former in membrane fabrication. the effect of iron-nickel oxide nanoparticles concentration in the casting solution on the membrane structure and performance was investigated. scanning optical ...

In this study, the efficacy of electron beam irradiation versus chemical coupling for yielding polyethersulfone (PES) membranes with antibacterial properties was investigated. For the surface coating, a recently discovered lead compound, IL-KKA, comprising a short peptide sequence functionalized with imidazolium groups, was used. For better integration within the membrane, several novel variant...

Micropollutants pose a significant threat to water quality, aquatic life, and public health. A catalytic polymeric membrane, combining membrane filtration peroxymonosulfate (PMS) activation provides an alternative option their treatment. In this work, CoFe2O4 based particles were blended with polyethersulfone (PES) polymer UF (ultrafiltration) membranes fabricated by non-solvent induced phase i...
