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 Desalting with Ion-Exchange Membranes
Nature, 1956SEPARATION of amino-acids and other substances by paper chromatography must often be preceded by the removal of inorganic salts. The common methods1 require careful supervision, and under optimal conditions a loss of 10–20 per cent of many amino-acids may occur with 50 per cent loss of arginine by conversion to ornithine2. A simplified form of desalter,

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.

Specific ion effects on membrane potential and the permselectivity of ion exchange membranes
Phys. Chem. Chem. Phys., 2014Membrane potential and permselectivity are critical parameters for a variety of electrochemically-driven separation and energy technologies. An electric potential is developed when a membrane separates electrolyte solutions of different concentrations, and a permselective membrane allows specific species to be transported while restricting the passage ...

Ion exchange membranes in ion chromatography and related applications
Talanta, 2019This review is a broad survey of ion exchange membranes (IEMs) in chosen areas of analytical chemistry. The coverage is comprehensive in ion chromatography (IC) applications, this includes in-line water purification for IC use, chemical and electrodialytic eluent suppression, eluent generation, eluent purification, pH modification, buffer generation ...

Electrical capacitance of ion-exchanger membranes
Journal of Theoretical Biology, 1967Abstract The electrical impedance of ion-exchanger membranes between identical solutions of uni-univalent electrolyte was studied. At subaudio frequencies there was a large capacitance (Farads/cm 2 ) which varied with frequency, electrolyte concentration, individual diffusion constant of membrane co- and counter-ion, and sign of membrane charge.
