Abstract
A process for separating hydrophobic organic liquids from water comprising passing a mixture of water and hydrophobic organic liquids through a column-like vessel which is filled with a hydrophobic, preferably open-celled, polyurethane foam, said foam having a high absorption capacity, permits high flow-through velocities even as the foam becomes covered and saturated with the hydrophobic organic liquids, is reversibly deformable, and can be reused.
