METHOD FOR PREPARING POLYAMIDE-BASED REVERSE OSMOSIS MEMBRANE HAVING REMARKABLE SALT REJECTION AND PERMEATION FLUX, AND REVERSE OSMOSIS MEMBRANE PREPARED BY SAID PREPARATION METHOD

摘要

The present disclosure provides a method of manufacturing a reverse osmosis membrane, the method including: forming an aqueous solution layer containing a multifunctional aromatic amine compound on a porous support; forming a polyamide active layer by bringing an organic solution containing an acyl halide compound to contact an upper portion of the aqueous solution layer; and allowing an organic solution containing a multifunctional aromatic amine compound to contact an upper portion of the polyamide active layer, and a reverse osmosis membrane manufactured by the manufacturing method.
