OSTI ID:5322837
In a method for separating extraction solvents from extract of raffinate phases by selectively permeating the extraction solvent through a cellulose or cellulosic membrane under reverse conditions. This paper describes an improvement comprising using a cellulose or cellulosic membrane which has been dried, rewet and redried before being used to effect the desired separation.
