| titleOfInvention | Highly permeable composite reverse osmosis membrane and method of producing the same |
| abstract | The present invention provides a composite reverse osmosis membrane as a polyamide membrane including a side chain amino group such as a residue of a polyvinyl alcohol-based amine compound represented by Formula 1. Such a membrane can remove organic impurities under a low pressure, providing an economical method for removal of impurities. An aqueous solution including a polyvinyl alcohol-based amine compound having a side chain amino group represented by Formula 1 is applied on a polysulfone-based ultrafiltration membrane as a microporous support. Next, trimesic acid chloride solution is applied causing interfacial polycondensation, which generates a reverse osmosis membrane. When this composite reverse osmosis membrane is evaluated by using a pH 6.5 aqueous solution including 500 mg/l of sodium chloride at an operation pressure of 5 kg/cm 2 and at a temperature of 25° C., the permeable flux is at least 1.5 m 3 /m 2 ·d, and the salt rejection is 80% or less. n n nwherein 0<a, 0≦b, 2<c, 1≦x≦5, 0≦y≦4; R 1 is at least one group selected from the group consisting of an ether group, an alkylene group and an ester group; and R 2 is at least one group selected from the group consisting of an alkyl group and a halogen group. |
