Abstract
A reverse osmosis membrane having excellent antifouling property, which is advantageous in terms of fundamental prevention of fouling generated by inorganic crystalloids, organic contaminants, and microorganisms, and a method for preparing the same. The membrane can be manufactured by hydrolyzing a titanium compound in an acidic aqueous solution to produce TiO particles of nano scale; dispersing the produced TiO particles in an acidic aqueous solution of pH 1-6 or an alkaline aqueous solution of pH 9-13 to yield a stable TiO dispersed solution; and immersing a reverse osmosis membrane prepared by a known method in the TiO dispersed solution to incorporate TiO into the membrane.
