Fundamental studies of a new series of anion exchange membranes: membrane preparation and characterization

Chemical cross-linking anion exchange series membranes were prepared from linear engineering plastics poly(2,6-dimethyl1,4-phenylene oxide) (PPO) by conducting the processes of bromination and amination at both benzyl and aryl positions. Compared with the traditional technologies, the membrane route described in this paper has cancelled the chloromethylation process and thus, given up the use o...

The Role of Ion Exchange Membranes in Membrane Capacitive Deionisation

Ion-exchange membranes (IEMs) are unique in combining the electrochemical properties of ion exchange resins and the permeability of a membrane. They are being used widely to treat industrial effluents, and in seawater and brackish water desalination. Membrane Capacitive Deionisation (MCDI) is an emerging, energy efficient technology for brackish water desalination in which these ion-exchange me...

Preparation and Evaluation of Anion-Exchange Polymer

Preparation and Characterization of Heterogeneous PVC-Silica Proton Exchange Membrane

Heterogeneous proton exchange membranes (PEM) are synthesized using the dry phase inversion technique. The casting solutions are prepared by dispersing a finely ground cation exchange resin particle in N,N-dimethylacetamide (DMAc) solution of polyvinyl-chloride (PVC). Results show that ion exchange capacity is increased with the addition of 1 %-wt nanosilica (from 0.14 to 0.27 meq/g) while it i...
