| titleOfInvention | A kind of preparation method of reverse osmosis membrane |
| abstract | The present invention provides the preparation method of a kind of reverse osmosis membrane, polymerization procedure and post-processing step, wherein said post-processing step is particularly as follows: after the organic solvent on film surface volatilizees completely, immerse containing 10 600s in the aqueous solution of the modifying agent of 0.1% 10wt% immediately, i.e. prepare reverse osmosis membrane, and the reverse osmosis film bubble prepared is entered in pure water.The membrane flux of modified reverse osmosis membrane can promote 20% 40% on the basis of evc flux, within the salt rejection rate of film can keep increasing degree 13 percentage points substantially, improves the overall performance of reverse osmosis membrane. |
