In conventional extraction columns (see Fig. ) for a heavy or light solvent column, flooding places an upper limit on the maximum the density difference between the two phases is low, separation becomes a problem.
When a suitable solvent is immobilized in a porous medium, absorption and extraction can be carried out like conventional pressure swing adsorption.

What is Solvent Extraction. Solvent Extraction, also known as liquid-liquid extraction, is a method to separate compounds based on their relative solubilities in two different immiscible liquids, usually water and an organic solvent.
Importance of the process: The Solvent Extraction(S.E.) process was first developed as a tool of analytical.

Additional research should be conducted for the investigation of water renovation by solvent extraction as applied to reduction of halo- genated hydrocarbons and other refractory compounds which affect potable water supplies and aquatic and marine life with respect to tainting and odors or toxicological manifestations either directly or through bio- logical.
Solvent extraction, also known as Liquid–liquid extraction or partitioning, is a method to separate a compound based on the solubility of its parts. This is done using two liquids that don't mix, for example water and an organic solvent.
