Class Information
Number: 210/644
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 > Diffusing or passing through septum selective as to material of a component in liquid/liquid solvent or colloidal extraction
Description: Process in which a constituent of the liquid being treated diffuses through a material which acts as a barrier to other constituents of the liquid and a constituent is preferentially dissolved in a second liquid usually contacting the other side of the barrier material.
