Process for producing semipermeable membrane. |
摘要 |
<p>A process for producing a semipermeable membrane having a high flux, excellent in solute rejection and useful for reverse osmosis, ultrafiltration and the like which comprises dipping a semipermeable membrane of acrylonitrile polymer containing 40-100% by mole of acrylonitrile in a solution of an amine and/or an alkali, or casting a solution of said polymer containing an amine and/or an alkali to prepare a semipermeable membrane, and optionally, treating the semipermeable membrane thus obtained with plasma.</p> |
