    • PURPOSE: A polyamide reverse osmosis membrane and a manufacturing method thereof using a polysulfone support having a multi-walled carbon nanotube are provided to use a polysulfone support with a polysulfone membrane containing a carbon nanotube and maintaining a chemical tolerance and mechanical properties identical to the properties of an existing membrane, thereby maintaining a salt rejection rate and improving permeable behaviors compared with an existing reverse osmosis membrane using the polysulfone support. CONSTITUTION: A manufacturing method for a polyamide reverse osmosis membrane includes: a step(S100) of opening the terminal portion of a multi-walled carbon nanotube with heat treatment in order to improve an unstable terminal portion structure of the multi-walled carbon nanotube such as a pentagonal ring or a heptagonal ring; a step(S200) of surface-treating the multi-walled carbon nanotube, of which the terminal portion is open, with a nonionic surfactant in order to increase the dispersive properties of the multi-walled carbon nanotube against an organic solvent; a step(S300) of manufacturing a polysulfone solution added with the surface-treated multi-walled carbon nanotube into a polysulfone membrane containing the multi-walled carbon nanotube using a nonsolvent-induced phase separation method; and a step(S400) of impregnating an M-phenylenediamine aqueous solution and a trimesoyl chloride organic solution using the polysulfone membrane as a support, and drying the polysulfone membrane to manufacture the polyamide reverse osmosis membrane. [Reference numerals] (AA) Start; (BB) End; (S100) Step of opening the terminal portion of a MWCNT(Multi-walled Carbon Nanotube) with heat treatment in order to improve the unstable terminal portion structure of the multi-walled carbon nanotube such as a pentagonal ring or a heptagonal ring, where the MWCNT is used as a flow path for reducing the resistance of a polysulfone support in a reverse osmosis membrane; (S200) Step of surface-treating the MWCNT of which the terminal portion is opened using a nonionic surfactant in order to increase the dispersive property of the MWCNT against an organic solvent; (S300) Step of manufacturing a polysulfone solution added with the surface-treated MWCNT into a polysulfone membrane containing the MWCNT using a nonsolvent-induced phase separation method; (S400) Step of impregnating the polysulfone membrane containing the MWCNT as a support in an MPD aqueous solution and a TMC organic solution, and then drying to manufacture the polyamide reverse osmosis membrane;
