in solvent extraction
Also contains definition of: cosolvent
The liquid or homogeneous mixture of liquids in which extractant(s) and possible modifier(s) may be dissolved to form the solvent phase.
  1. The term @C00859@, which implies an @I03026@ diluent is not recommended.
  2. 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 @L03587@, although the term cosolvent may be used in certain circumstances.
  3. The diluent by itself does not extract the main (extractable) solute appreciably.
