| titleOfInvention | A kind of large flux reverse osmosis membrane and its preparation method and application |
| abstract | The invention discloses a preparation method and application of a large flux reverse osmosis membrane. The reverse osmosis membrane comprises a porous support membrane and a polyamide layer formed on the support membrane, and the polyamide layer is prepared by interfacial polymerization reaction from an aqueous phase solution containing a polyfunctional amine monomer and an organic phase solution of a polyacid halide. The multifunctional amine aqueous phase solution contains 0.001-3.0 wt% of B family water-soluble vitamins. The reverse osmosis membrane prepared by the method has higher water flux on the basis of maintaining a higher desalination rate, and has good application prospects in water treatment fields such as industrial water supply and waste water reuse. |
