| titleOfInvention | Modified polyamide desalting layer, reverse osmosis membrane and preparation method and application thereof |
| abstract | The invention relates to a modified polyamide desalting layer, a reverse osmosis membrane, a preparation method and application thereof. According to the invention, monoamino hydroxy flavone is used for modifying the polyamide desalting layer, and the addition of the substance can endow the reverse osmosis membrane with good oxidation resistance and simultaneously obtain the effect of improving the membrane flux. In the preferred scheme, (2-aminobenzyl) triphenyl phosphine bromide is added, so that a reverse osmosis membrane with biological pollution resistance, oxidation resistance and high flux can be obtained, and the reverse osmosis membrane can be applied to water treatment, so that the treatment efficiency can be further improved, and the production cost can be reduced. |
