Method for producing highly permeable composite reverse osmosis membrane |
| abstract |
Disclosed is a method for producing a composite reverse osmosis membrane comprising the steps of coating a porous support with (A) a solution containing a compound having at least two reactive amino groups per molecule and bringing (B) a solution containing a polyfunctional acid halide into contact with the solution (A) to induce crosslinking to form a crosslinked polyamide skin layer, in which the crosslinking is carried out in the presence of a substance having a solubility parameter of 8 to 14 (cal/cm³) 1/2 . The resulting composite reverse osmosis membrane exhibits high salt rejection and high water permeability. |
