Method for producing composite semipermeable membrane |
| abstract |
(57) [Summary] [Object] To obtain a composite semipermeable membrane capable of selectively separating and removing contaminants and trace harmful substances contained in raw water to enable high water recovery operation. A mixed amine component of an aliphatic polyfunctional amine and an aromatic polyfunctional amine, and a mixed acid halide component of a polyfunctional acid halide and a polyfunctional acid anhydride halide are interfaced on a porous support film. A method for producing a composite semipermeable membrane, comprising: forming a thin film of a crosslinked polyamide by performing a polycondensation reaction, and then contacting the thin film with an aqueous alkaline solution having a pH of 11 or more. |
