REVERSE OSMOSIS MEMBRANE WITH THE EXCELLENT HYDROPHILE PROPERTY AND CHLORINE RESISTANCE, AND A PRODUCING METHOD THEREOF

摘要

PURPOSE: A reverse osmosis membrane and a producing method thereof are provided to improve the chemical resistance of the reverse osmosis membrane by forming a reformed layer and an ion complex layer.;CONSTITUTION: A reverse osmosis membrane with the excellent hydrophile property and chlorine resistance comprises the following: a reformed layer(200) formed on the upper side of a porous supporter(100) and the lower side of a polyamide active layer(300); and an ion complex layer(400) formed on the surface of the polyamide active layer. The reformed layer is formed by processing the porous supporter with a sodium hydroxide solution and a hydrochloric acid solution.;COPYRIGHT KIPO 2011
