Method for producing a polyamide reverse osmosis membrane and a polyamide reverse osmosis membrane manufactured thereby |
| abstract |
The present invention is a step of coating a microporous support with an aqueous polyfunctional amine solution containing 0.01 to 0.5% by weight of carbon nanotubes and 0.1 to 20% by weight of a polyfunctional amine, the porous tube on the microporous support coated with the polyfunctional amine solution Preparation of a polyamide reverse osmosis membrane comprising the step of forming a thin film by interfacial polymerization by contacting an aliphatic hydrocarbon-based organic solution containing 0.01 to 1% by weight of the acyl halide, and drying and washing the obtained thin film. Regarding the method, the polyamide-based reverse osmosis membrane of the present invention has high salt rejection rate and high flow rate characteristics, and thus may be usefully used for salt water and seawater treatment. |
