Electrodialysis of Blood Using Ion-Exchange Membranes
THE correction of electrolyte imbalance and the removal of retention products of the blood during renal failure is at present achieved by the use of artificial kidneys which permit the diffusion of solutes through a semi-permeable membrane. Several types of apparatus used successfully for hemodialysis include those described by Kolff and Watschinger (1956) and Alwall, Norviit, and Steins (1948)...
متن کاملIon-exchange membranes" preparative methods for electrodialysis and fuel cell applications
Ion-exchange membranes have been used in various industrial processes, e.g., in the electrodialytic concentration of seawater to produce edible salt, as a separator for electrolysis, in the desalination of saline water by electrodialysis, in the separation of ionic materials from non-ionic materials by electrodialysis, in the recovery of acid and alkali from waste acid and alkali solution by di...
متن کاملElectrodialysis Heterogeneous Anion Exchange Membranes Filled with TiO2 Nanoparticles: Membranes' Fabrication and Characterization
In the current research, polyvinylchloride based mixed matrix heterogeneous anion exchange membranes were prepared by a solution casting technique. Titanium dioxide nanoparticles were also utilized as inorganic filler additive in the membrane fabrication. The effect of TiO2 nanoparticles concentration in the casting solution on the membrane physico-chemical properties was studied. Membrane wate...
متن کاملSorption of pesticide endosulfan by electrodialysis membranes
Endosulfan (ES) is a micropollutant found in reverse osmosis concentrates from water reuse applications. Electrodialysis (ED) can remove and recover charged solutes from such concentrates. While polar compounds cannot normally be removed, their fate in ED is important as they can contribute to membrane fouling/poisoning and be released during cleaning. High adsorption of ES to ED membranes was ...
متن کاملSorption of steroidal hormones by electrodialysis membranes
14 The mechanisms of sorption of four steroidal hormones – estradiol, estrone, progesterone and 15 testosterone – to electrodialysis (ED) membranes were investigated as a function of solution pH 16 and presence of humic acid (HA). Hormone-membrane partition coefficients (log KAEM/CEM) 17 determined through sorption isotherm experiments suggested that hormone sorption was due to 18 hydrogen bond...
