The liquid or homogeneous mixture of liquids in which
extractant(s) and possible modifier(s) may be dissolved to form the solvent phase.
Notes:
- The term carrier, which implies an inert diluent is not recommended.
- Although the diluent may well be a single liquid or even the major portion of the extracting phase, the term solvent should not be used in this sense as it has a much wider meaning in the context of liquid-liquid extraction, although the term cosolvent may be used in certain circumstances.
- The diluent by itself does not extract the main (extractable) solute appreciably.
