REVERSE OSMOSIS SEPARATION MEMBRANE EXCELLENT IN SALT REMOVAL RATE AND PERMEATION FLOW CHARACTERISTICS AND PRODUCTION METHOD OF THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a reverse osmosis separation membrane with an improved salt removal rate and permeation flow characteristics capable of further enhancing the salt removal rate and permeation flow characteristics, and production method of the same.;SOLUTION: A reverse osmosis separation membrane comprises: a microporous support layer; and a polyamide active layer formed on the microporous support layer, and including one or more types of graphene-containing compound. The polyamide active layer is formed of an interfacially polymerized substance including: an amine compound as amine aqueous solution containing 0.0005 - 0.05 wt.% of the one or more types of graphene-containing compound; and an acyl halide compound.;COPYRIGHT: (C)2016,JPO&INPIT
