A term used to describe a liquid-liquid extraction
process that involves a transfer of ionic species from the extractant
to the aqueous phase in exchange for ions from the aqueous phase. The term does not
imply anything concerning the nature of the bonding in the extracted complex. The
term solvent ion exchange
is not recommended.
