ABSTRACT:
The instant invention is directed to a method of solvent extraction. The steps of the method include: providing a dual-skinned asymmetric membrane; providing a feed containing a solute; and providing a solvent. The feed and the solvent are contacted across the membrane. The solute of the feed is extracted, and forming thereby a raffinate and an extract.
