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 ...

Separation of organic acids with electrodialysis

, 2022
S.202-209 : Abb.For the downstream processing in fermentation and enzymatic processes, electrodialysis can be used very efficiently. It is shown that bipolar membrane technique is a very economic way for the separation of organic acids like itaconic acid,

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 ...

Wine acidification methods: a review

OENO One, 2023
Global warming is directly linked to a lower concentration in organic acids in grape berries, leading to higher pHs in wine. Because of this lack of acidity, many important factors are impacted, as wine acidity and pH play a crucial role in various ...

Resource utilization of high-salinity mine water through the membrane-integrated process based on bipolar membrane electrodialysis

Meitan xuebao
In the context of “zero discharge” of mine water and the reverse distribution of coal and water resources in the western mining areas, the direct discharge of high-salinity mine water without proper treatment not only causes immeasurable damage to the ...

Co-ion fluxes of simple inorganic ions in electrodialysis metathesis and conventional electrodialysis

, 2015
The main functionality of ion-exchange membranes is to selectively permeate either cations or anions. However, co-ions may permeate as well to some extent through these membranes.

Electrodialysis - state of the art

, 2017
Otpadne vode predstavljaju velik problem za okoliš jer svojim odlaganjem na njega uvelike utječu. Zato je često potrebno ukloniti određene kontaminante iz vode kako bi se ona mogla ispustiti iz sustava, ali i ponovno koristiti kao tehnološka voda ili čak
