| titleOfInvention | High flux aromatic polyamide reverse osmosis membrane using additives and method of making |
| abstract | The invention relates to a high-flux aromatic polyamide reverse osmosis membrane using an additive and a preparation method thereof; the aromatic polyamide composite reverse osmosis membrane uses an amide compound containing carbon-carbon double bonds as an additive of an aqueous phase solution and carries out ultraviolet-initiated polymerization on the amide compound; is formed by connecting amido bonds in the aromatic polyamide layer and on the surface with carbon-carbon double bonds of the amide compounds. Preparing an aqueous phase solution containing 0.1-1.0% of amide compounds containing carbon-carbon double bonds and 0.1% of photoinitiator 2959 for reaction; after the interfacial polymerization reaction is finished, carrying out free radical polymerization reaction on the primary membrane; and (4) placing the irradiated reverse osmosis membrane in an oven for heat treatment, and drying the membrane to obtain the reverse osmosis membrane. The preparation process is simple, the operation time is short, the implementation is easy, the cost is low, and the water flux of the reverse osmosis membrane is greatly improved on the basis of keeping the salt rejection rate of the reverse osmosis membrane without the additive. |
