electromembrane extraction

initialism: EME
https://doi.org/10.1351/goldbook.10278

Hollow-fibre liquid-phase microextraction in which the extraction is driven by an electrical potential sustained between the sample solution and the acceptor phase, separated by a supported liquid membrane.

Notes:
  1. A typical experimental arrangement is shown in the figure below.
  2. Electromembrane extraction is typically performed in three-phase mode (\(\ce{aqueous\!->\!organic\!->\!aqueous}\)).
  3. The sample is agitated or stirred during extraction.

Typical experimental arrangement for electromembrane extraction of cations (anions extracted by reversing the polarity). SLM, supported liquid membrane in the form of a porous hollow fiber with solvent-filled pores.
