The term applied to the whole initial liquid phase containing the
extractant.
Notes:
-
The solvent may contain only one extractant or it may be a composite homogeneous mixture of extractant(s) with diluent(s) and also sometimes modifiers and accelerators.
-
The term solvent must not be used as a synonym for any of the individual components of a composite liquid phase even where, in the case of a single component (e.g. 3-methylbutan-2-one or tributyl phosphate), it becomes identical with the extractant.
-
The term may be qualified to denote the extract from a given processing step e.g. loaded solvent.
