... one (facilitative electromigration). Desalination 149 (2002) 405–409 Demineralization and separation of amino acids by electrodialysis with ion-exchange membranes T.V. Elisseeva*, V.A. Shaposhnik, I.G. Luschik Voronezh State University, Universitetskaya sq., 1, Voronezh, Russia 394006 Tel. + ...
Desalination 149 (2002)

The simultaneous recovery of trivalent and tetravalent chromium ions through charged ion-exchange membranes by using three detachable cells was tested at different current densities. The effect of mono- and divalent valence ions correspondin ...
Desalination 171 (2004)

... an industrial plating plant was investigated in a batch electrodialysis system. The experiments were carried out using two different types of ion-exchange membranes. The effects of applied potential, pH value and initial silver concentration on the duration of electrodialysis and energy consumptio ...
Desalination 172 (2005)

The structural, selective and electrokinetic characteristics and percolation parameters were determined for different ion-exchange polymer membranes from their conductivity data using the two-phase model of membrane conductivity and percolation theory. The two differen ...

... of highly sulfonated particles were as conductive as Nafion 117 membranes and had high values of permselectivity in HCl solutions. Heterogeneous ion-exchange membranes can be prepared by blending sulfonated poly(1,4phenylene sulfide) particles and linear polyethylene and subsequent compression-moldin ...
Desalination 198 (2006)

Based on the Nernst–Planck equations of ion flow, a simple model was proposed for the current–voltage characteristics of an ion-exchange membrane under limiting current density. The numerical analysis depicts the influence of parameters such as solution concentration, diffusio ...
Desalination 173 (2005)

... of interpolymer and heterogeneous membranes was carried out by measurement of electrical resistance, counter-ion transport number, ion-exchange capacity and volume fraction of water. Interpolymer ion-exchange membranes exhibited better electrochemical and electrodialytic properties i ...

... for the continuous production of high-purity water without the use of chemicals. The study was carried out with a laboratory pilot. The ion-exchange membrane stack has eight cell-pairs of which four dilute compartments were filled with mixed-bed ion-exchange resins. The feed is tap water wit ...

... is studied and the procedures of their recovery from various mixtures are suggested. Peculiarities of basic amino acids transfer through the ion-exchange membranes are closely connected with their amphoteric nature and high values of isoelectric points in comparison with neutral amino acids.
Desalination 241 (2009)

... operations in the surface treatment industry. The case study is acid picking before electroplating. The first step is the study and selection of ion-exchange membrane couples. The second step is the development of tools to promote the use of ED applied to industry. Tracer methods and surface treatmen ...
