The properties and preparation procedures of ion-exchange membranes are closely related to those of ion-exchange resins. As with resins, many types of membranes are possible with different polymer matrixes and different functional groups to confer ion-exchange properties on the product.

The name “ion-exchange membranes” arose because the first such articles were made by preparing in sheet form the conventional organic ion-exchangers available 30 years ago. The purpose of these membranes is not to exchange ions but to transmit them in a controlled way.

Methods of preparing cation- and anion-exchange membranes with low areal resistances were developed for use in lower cost desalination of seawater. Membranes of both types were prepared having the desired resistance of 1 Ω . cm or less. Preparation involved using reinforcements to strengthen polymer compositions.

Studies with inorganic ion-exchange membranes
Talanta, 1978The pyridinium molybdoarsenate membrane shows a response to pyridinium ions and can be used to determine the concentration of these ions in the range 10(-3)-1M. The potentials generated across the membrane are reproducible and the response time is less than 1 min. There is no interference from certain inorganic and organic ions.

Cellulosic ion‐exchange membranes for hemodialysis
Journal of Biomedical Materials Research, 1977AbstractThe application of cellulosic ion‐exchange membranes to hemodialysis was studied in vitro. The membranes were prepared by radiation‐grafting methacrylic acid and vinylpyridine to films of DuPont cellophane PD‐215 to produce cation‐exchange and anion‐exchange membranes, respectively.Solutions of urea, creatinine, glucose, and uric acid were ...

Electrolytic Separation of Ions by Ion‐Exchange Membranes
Berichte der Bunsengesellschaft für physikalische Chemie, 1978AbstractThe ion separation by ion‐exchange membranes appears to be of interest as an energy‐saving, continuous and economical process. The separation of ions of the same valency can only be achieved through membranes which have specific interaction with these ions.
