Fractionation of aqueous sodium salts by liquid–liquid extraction in aqueous two phase systems

Liquid–liquid extraction-based process concepts for recovery of carboxylic acids from aqueous streams evaluated for dilute streams

“…This facilitates the transfer of carboxylic acid molecules into the organic solvent phase, and minimizes solvent leaching (Pratiwi et al, 2015). This practice is known in the literature as "salting out" (Milosevic et al, 2014(Milosevic et al, , 2013. It should be noted that the added electrolyte must not interact with carboxylic acids in such a way that their molecular (undissociated) forms are disturbed.…”
