The process of removing solute(s) from a loaded solvent or extract. Generally this refers to the main solute(s) present.
- Where appropriate, e.g. when liquid-liquid distribution is used for stripping, the term [email protected]@ can be used. The terms back-washing and @[email protected] are not recommended.
- The recent application of selective stripping of solutes as a separation method leads to some confusion between the terms stripping and @[email protected] It is recommended that the term @[email protected] be reserved for the operation of removing contaminants (impurities) from an extract (where the scrub @[email protected] is often recycled to the loading step) and the term selective stripping be used where two or more main solutes are stripped successively from an extract, usually with different stripping agents, with a view to their subsequent separate @[email protected] from solution for analysis.
