A term describing the co-operative effect of two (or more) extractants where the distribution
ratio for the combination is greater than the largest individual distribution ratio
(measured under comparable conditions).
Notes:
-
The corresponding adjective is synergic and the term synergistic should not be used.
-
No standard method for quantification of the phenomenon has been agreed and any approach
should be clearly defined in a given situation.
