Separation of organic acids from water using ionic liquid assisted electrodialysis.

Highlights: [•] An ionic liquid was used as a solvent to improve electrodialysis technology. [•] Sodium butyrate was our model organic salt for current transport. [•] Both electrodialysis and bipolar electrodialysis were tested with ionic liquids. [•] Ion transport occurred into the ionic liquid from an aqueous solution. [•] Ionic liquids showed potential to reduce product separation energy and cost requirements. [Copyright &y& Elsevier]
