Within an electrodialysis unit, the solutions are separated by alternately arranged anion exchange membranes (permeable only for anions) and cation exchange membranes (permeable only for cations). The membranes are arranged parallel to one another to form an electrodialysis stack. When a potential is applied across the selectively permeable membrane stack, anions selectively move through the an...

In this study, commercially available cation- and anion-exchange membranes were investigated in hybrid liquid/gas electrolyzers by coupling situ ambient pressure hard X-ray photoelectron spectroscopy with finite element analysis.

the hybrid molten/solid in2o3 - 30-48 wt.% bi2o3 oxide materials were studied with respect to their transport properties. the conductivities, oxygen ion transport numbers and oxygen permeation fluxes have been measured by using the four-probe dc, volumetric measurements of the faradaic efficiency and gas flow techniques, respectively. we show that the oxygen permeability of the hybrid molten/so...

Salinity gradient energy, which is also known as Blue energy, is a renewable energy form that can be extracted from the mixing of two solutions with different salinities. About 80% of the current global electricity demand could potentially be covered by this energy source. Among several energy extraction technologie...

Herein, we report on the fabrication of a device for removing cations of an anti-analyte ion contained in a sample and an eluent under an electric field. The space in which the electrode is set on both sides of the device is separated into three cells using anion and cation exchange membranes. Each of the cells is packed with either an anion or cation exchange resin. Cation removal is perfor...

This paper reports on a new suppressor that can be used in the ion chromatography (IC) of inorganic cations. The space in which the electrode is set on both sides of the device is separated into three cells using anion- and cation-exchange membranes. Each of the cells is packed with either an anion- or cation-exchange resin. Anions in the eluent and injected sample are removed by electrical reg...
