SPC/PVDF membranes for emulsified oily wastewater treatment
(Elsevier Science, 2009-01)
New membranes based on sulfonated polycarbonate (SPC) and polyvinylidene fluoride (PVDF) were prepared. SPC was obtained by treating polycarbonate (PC) with acetyl sulfate. The ion exchange capacity (IEC) of the sulfonated ...
Ionic Transport and Water Vapor Uptake of Ammonium Exchanged Perfluorosulfonic Acid Membranes
(ELECTROCHEMICAL SOC INCPENNINGTON, 2012)
Nafion membranes series N117 doped with ammonium, at different cation fractions (H+/NH4+), were investigated for ionic transport and water vapor uptake, for several water activities and temperatures. Ammonium cations change ...

On the chemistry of ion exchange in monomolecular layers of lipids
(1969)
The main purpose of this work has been to study further the association of cations and anions with cell membrane lipids, in particular with phosphatidylcholine. The adsorption of Ca2+ or SO4 2- to phosphatidylcholine ...
