“…These new HNH2 membranes synthesized from S‐PES were elaborated by casting method as detailed in Reference, [ 29,31 ] in presence of NH2‐PES used as a crosslinking agent. As previously measured using NMR, [ 29 ] the sulfonated polymer, and the crosslinking agent contain, respectively 1.3 proton per monomer unit and 1 AMine per monomer unit.…”

“…The weight of the wet membranes was then noted after elimination of the surface water with a hydrophilic paper. Water uptake (WU) values were obtained using following Equation (1) [ 20,21,31,33 ] :

italicWU = \frac{W_{wet} - W_{dry}}{W_{italicdry}} * 100

where W wet and W dry are respectively, the wet and dry weights of the membranes.…”

In this research work, the synthesis and characterization of new ion exchange membranes made from sulfonated polyether sulfone (SPES) crosslinked by aminated PES (NH2PES) crosslinking reagent have been investigated for electrodialysis (ED) applications. Sulfonated and aminated PES have similar chemical structures that allow a good compatibility, the only difference between them is their functional groups. This membrane (called HNH2) has been obtained by reaction between SPES with 1.3 SO3H groups per monomer unit and the calculated equivalent amount of NH2PES. Three HNH2 membranes have been fabricated with different degrees of sulfonation. The HNH2 membranes properties have been evaluated using different characterization analysis. The results have shown that HNH2 membranes appear to be very promising candidates for electrochemical applications.

“…Droplets of adsorbed water on the membrane surface were absorbed by hydrophilic tissue paper. From the difference in mass, before and after complete drying of the membrane, WR values were measured, 30‐32 as the relative weight gain per gram of dry sample using the following Equation (1):

normalWR = \frac{W_{wet} - W_{dry}}{{normalW}_{normaldry}} * 100,

where W wet and W dry are the weights of the wet and dry membranes, respectively.…”

The purpose of this work is to study the desalination of brackish water using a new ion exchange membrane, made from sulfochlorated polyethersulfone (Cl-PES), and crosslinked using aminated polyethersulfone (NH2-PES) as a crosslinking reagent. This membrane, named ClNH2 membrane, has been obtained by reaction between Cl-PES with 1.3 SO 2 Cl groups per monomer unit and 0.2 equivalent amount of NH2-PES. ClNH2 membrane has been characterized in terms of contact angle, transport number, intrinsic conductivity, and water uptake (as a function of temperature). Electrodialysis performances of the newly synthetized membranes have been measured using an electrodialysis cell at a laboratory scale and compared to commercial membranes. All the experiments have been performed using synthetic brackish water solutions prepared from sodium chloride salts with different concentrations (varying from 0.5 to 5.0 g/L). The concentration of different water samples obtained has been found to be below the amount recommended by the World Health Organization (WHO) for drinking water.
