re-extraction [obsolete]
Since the prefix 're' can signify 'back' as well as 'again' this term is ambiguous and should be avoided, except where the process of @E02301@(e.g. from aqueous solution to an organic phase) in a single direction is repeated (following @S06054@). It should not be used as a synonym for @S06054@ or back-@E02301@.
