Studies on soil reaction VII An electrodialysis apparatus for the determination of replaceable bases in soils

, 1931
1. A simple form of two-compartment electrodialysis cell is described for the determination of replaceable bases in sets of six soils at a time. The determination requires little attention and the total replaceable bases are obtained by direct titration ...

Study of the mass transfer phenomena involved in an electrophoretic membrane contactor [PDF]

, 2001
Electrophoretic separators, in which a porous membrane is used as a contactor, offer the possibility to scale up electrophoresis as well as to extend the field of application of electrodialysis to fractionate polyamino acids, peptides or small proteins ...

Removal of Monovalent and Divalent Cations from Brine Water by Electrodialysis Using Modified Polyethersulfone Membranes

Tikrit Journal of Engineering Sciences
In electrodialysis, an ion exchange membrane removes unwanted ions from wastewater and toxic metal ions from effluents. Montmorillonite-based modified "polyethersulfone membranes" have been studied as a potential small-scale electrodialysis approach for

Application of Electrodialysis to Production of High-Purity Perrhenic Acid

Separations
Laboratory tests were conducted for the production of high-purity perrhenic acid using a membrane technique—electrodialysis. Four solutions were used in the tests: diluate, concentrate, anolyte, and catholyte.

Electrodialysis of LiPF6 in Aqueous Solution for Wastewater Treatment in Hydrometallurgical Recycling of Lithium‐Ion Batteries

Advanced Energy & Sustainability Research
In the deactivation of spent lithium‐ion batteries (LIBs) by crushing in water for small‐scale recycling, one of the most difficult challenges is the treatment of wastewater containing LiPF6 due to the slow decomposition rate of PF6−.

Synthesis of amino acid ionic liquids from precursor [EMIM]OH via bipolar membrane electrodialysis

, 2010
A new environmentally benign process for the production of aqueous solutions of 1,3-dialkylimidazolium hydroxide [EMIM]OH is presented. Electrodialysis (ED) is an electrochemical membrane separation process in which ions are separated or concentrated ...

Comparison of anionic membranes used to concentrate nitric acid to beyond the azeotropic mixture

The electrolysis of concentrated nitric acid solutions was carried out in an electrochemical cell with parallel plates (FM01-LC ICI). An anionic membrane that permits the migration of nitrate ions under the influence of an electrical field separated the ...
