  • Separation Using Semi-Permeable Membranes (AREA)

Abstract

PURPOSE: To prepare reverse osmotic membrane, which is highly resistant to compaction, which makes possible separation of components of a soln. e.g. sea water having high osmotic press., and which can be used for a long period of time, by use of polyamide having CONH2 group at the side chain as a base.
