Solution purifiion ScienceDirect
It is difficult to see a major role for this technology in solution purifiion, such as is already taken by the, much more selective, processes of cementation, ion exchange and solvent extrac tion. Liquid membrane processes, on the other hand, do offer the selectivity required of solution purifiion processes.
