Extraction method wherein charged analytes are extracted from an aqueous phase into an organic phase assisted by a chelating agent.

Note 1: The chelating agent also substitutes the water molecules in the coordination sphere of the metal ions. Consequently, the resultant metal chelates have a hydrophobic character which facilitates their transfer to the organic phase.

Note 2: The analytes are usually metal ions.
