Countercurrent Laminar Microflow for Highly Efficient Solvent Extraction

By modifying the walls of a glass microchannel so that one side is hydrophilic and the other hydrophobic, countercurrent laminar flow of an organic phase relative to an aqueous phase is effected (see picture). This system is applied to the efficient extraction of a cobalt complex from toluene into water.
