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: State of their development and perspective
During the last 50 years, ion exchange membranes have evolved from a laboratory tool to industrial products with significant technical and commercial impact. Today ion exchange membranes are receiving considerable attention and are successfully applied for desalination of sea and brackish water and for treating industrial effluents. They are efficient tools for the concentration or separation o...
متن کاملLong-term stable electroosmotic pump with ion exchange membranes.
We present the design, fabrication and test of a novel inline frit-based electroosmotic (EO) pump with ion exchange membranes. The pump is more stable than previous types due to a new flow component that ensures a controlled width of the diffusion layer close to the ion exchange membranes. The pump casing is constructed in polymers while the EO active part, the frit, is made in a nanoporous sil...
متن کاملPotentiometric sensors with ion-exchange Donnan exclusion membranes.
Potentiometric sensors that exhibit a non-Hofmeister selectivity sequence are normally designed by selective chemical recognition elements in the membrane. In other situations, when used as detectors in separation science, for example, membranes that respond equally to most ions are preferred. With so-called liquid membranes, a low selectivity is difficult to accomplish since these membranes ar...
متن کاملThe 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...
