Synthesis and Characterisation of a Polysulfone-Polyvinyl Alcohol Hydrogelic Material [PDF]

open access: yesInternational Journal of Electrochemical Science, 2016
Hydrogels are flexible materials that have found a niche in membrane science owing to their ability to absorb water without dissolving. The synthesis of polyvinyl alcohol-polysulfone hydrogel in the presence of N-hydroxy succinimide is presented herein ...

Electrospun polysulfone/poly(lactic acid) nanoporous fibrous mats for oil removal from water [PDF]

open access: yesAdsorption Science & Technology, 2019
The study of oil sorbents with high oil sorption capacity is of great significance for oil–water separation, especially for oil spillage on seawater. In this work, we report polysulfone, poly(lactic acid), and polysulfone/poly(lactic acid) nanoporous ...

Modified Polysulfone Membranes. IV. Gas Separation with Aminated Polysulfone Membranes. [PDF]

open access: yesSen'i Gakkaishi, 2000
Novel gas permeation membranes were prepared from polysulfones and amine-modified polysulfones. The introduction of the primary amine moiety into polysulfone membranes led to an increase in permselectivity toward CO2 in CO2/N2 separation and a significant increase in that toward O2 in O2/N2 separation.

Ageing of polysulfone membranes in contact with bleach solution: Role of radical oxidation and of some dissolved metal ions [PDF]

open access: yes, 2008
In water production plants using membrane processes, contact with chemicals such as chlorine plays an important role in membrane ageing. This experimental study was aimed at gaining a better understanding of the effect of hypochlorite cleaning solutions ...

Human hepatic cell behavior on polysulfone membrane with double porosity level [PDF]

open access: yes, 2013
In the membrane-based bioartificial livers developed up to now,the hepatic cells were located either in the fibers lumen or in the cartridge,with limited capacity for cell hosting.Here,we designed a polysulfone (PSU) membrane with a double porosity ...

Experimental study of the effects of hypochlorite on polysulfone membrane properties [PDF]

open access: yes, 2006
Although chemical solutions are widely employed to clean membranes, they can also be responsible for changes in membrane properties. The two major drawbacks are then either the functional properties of the membrane gradually change, so the production can

Removal of Lipopolysaccharide and Reactive Oxygen Species Using Sialic Acid Immobilized Polysulfone Dialyzer [PDF]

open access: yes, 2011
Sialic acid (N-acetylneuraminic acid, NANA) was covalently immobilized onto the surface of a polysulfone (PSF) hollow fiber membrane. Prior to the immobilization, the surface of PSF was treated with ozone, followed by grafting with acrylic acid, and then
