ABSTRACT OF THE DISCLOSURE In transferring solute from a liquid feed solution to a liquid extractant through a porous membrane, the feed solution and the extractant being substantially immiscible when in direct contact with each other, and one of them tending to preferentially wet the surface of the porous membrane to constitute a membrane-wetting liquid, the following process is employed. A first side of the porous membrane is contacted with the feed solution containing the solute and the second side of the porous membrane is contacted with the liquid extractant so that the feed solution and the extractant can come into contact through the pores of the membrane. An inter- face-immobilizing pressure difference is maintained between the feed solution on one side of the porous membrane and the extractant on the other side. The pressure difference is maintained in a direc- tion across the membrane in a pressure range that is effective to substantially prevent the membrane-wetting liquid from flowing through the membrane and dispersing in the fluid on the opposing side of the membrane. In this way the interface between the feed solution and the extractant at the porous membrane is immobilized.
