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)...

The effect of temperature on lithium isotope separation by electrodialysis using La0.57Li0.29TiO3 (LLTO) electrolyte was investigated in the range 298.15–323.15 K. rates mass 6 and 7 isotopes (6Li 7Li) moving through LLTO into pure water were determined inductively coupled spectrometry. An Arrhenius-type dependence observed for rate transfer 6Li 7Li electrodialysis. apparent activation energy t...

Cranberry juice is recognized for its nutraceutical properties. Recently, it was demonstrated that it is possible to enrich a cranberry juice in antioxidants from another cranberry juice by an electrodialysis with filtration membrane (EDFM) process. In order to transpose this technology on an industrial scale for the production of an antioxidant enriched cranberry juice, the present work aimed ...

Electro-convective vortices in ion concentration polarization under shear flow have been of practical relevance for desalination processes using electrodialysis. The phenomenon has been scientifically disregarded for decades, but is recently embraced by a growing fluid dynamics community due its complex superposition of multi-scale gradients in electrochemical potential and space charge interac...

Currently, there is an enormous amount of energy available from salinity gradients, which could be used for clean hydrogen production. Through the use of a favorable oxygen reduction reaction (ORR) cathode, the projected electrical energy generated by a single pass ammonium bicarbonate reverse electrodialysis (RED) system approached 78 W h m(-3). However, if RED is operated with the less favora...

Most commercial anion exchange membranes (AEMs) deploy quaternary ammonium moieties. Alternative cation moieties have been explored in AEMs for fuel cells, but there are no studies focused examining alternative tethered cations ionic separations—such as organic acid transport via electrodialysis. H-cell and conductivity experiments demonstrate that benzyl 1-methyl imidazolium groups polysulfone...
