A transparent narrow-bore polymeric tubing was filled with adjacent plugs of mL volumes of aqueous and organic solutions, which formed a stable five-phase micro-electromembrane (m-EME) system. For the simultaneous m-EMEs of anions and cations, aqueous donor solution was the central phase, which was sandwiched between two organic free liquid membranes (FLMs) and two aqueous acceptor solutions. On application of electric potential, anions and cations in the donor solution migrated across the two FLMs and into the two peripheral acceptor solutions in the direction of anode and cathode, respectively.
