Class Information
Number: 210/634
Name: Liquid purification or separation > Processes > Liquid/liquid solvent or colloidal extraction or diffusing or passing through septum selective as to material of a component of liquid; such diffusing or passing being effected by other than only an ion exchange or sorption process
Description: Process in which either (a) a dissolved or suspended constituent of the liquid is preferentially dissolved or dispersed into a second liquid, or (b) a constituent of the liquid is selectively allowed to migrate through a barrier.
