polysulfone membrane

Membranes have a lot of potential for harvesting microalgae, but membrane fouling is hampering their breakthrough. In this study, the effects charge and corrugated surface on filtration performance were investigated. The clean water permeance (CWP), microalgae efficiency flux microalgal broth determined using patterned polysulfone (PSf) membranes with different shapes patterns containing densit...

Esterification of oleic acid employing sulfonated polystyrene and polysulfone membranes as catalysts

Journal: :Polimeros-ciencia E Tecnologia 2021

In the present study, catalytic activity of dense, porous, electrospun membranes polysulfone (PSF) and with sulfonated polystyrene (PSF_PSS) have been evaluated in reactions esterification oleic acid methanol, times that varied from 10 to 480 minutes. Conversion biodiesel has confirmed by FTIR quantified through gas chromatography. The results showed catalysts used were effective reaction studi...

Hyperbranched Polymer Integrated Membrane for the Removal of Arsenic(III) in Water

Journal: Journal of Membrane Science and Research 2018

Catherine Ngila, David Vlotman, Soraya Malinga, Thabile Ndlovu,

This work demonstrates the synthesis, characterization and application of a hyperbranched polyethyleneimine/polysulfone (HPEI/PSf) thin fi lm composite (TFC) membrane. The membrane was accessed via an interfacial polymerization of trimesoyl chloride and HPEI. The membrane samples were characterized by Fourier Transform Infrared-Attenuated Total Refl ectance (FTIR-ATR) s...
