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:
- A typical experimental arrangement is shown in the figure below.
- Electromembrane extraction is typically performed in three-phase mode (\(\ce{aqueous\!->\!organic\!->\!aqueous}\)).
- 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.
