| titleOfInvention | Cellulose gel layer modified loose nanofiltration membrane for high-flux dye separation and preparation method and application thereof |
| abstract | The invention discloses a cellulose gel layer modified loose nanofiltration membrane for high-flux dye separation, and a preparation method and application thereof, wherein the nanofiltration membrane comprises an ultrafiltration base membrane which is coated and modified by codeposition of dopamine and carboxymethyl cellulose, and a gel layer which is of a compact three-dimensional network structure and is constructed on the surface of the modified ultrafiltration base membrane by utilizing twice cross-linking reactions of carboxymethyl cellulose under the action of a cross-linking agent, the thickness of the nanofiltration membrane is 110 mu m, the pore diameter of the nanofiltration membrane is 1.38nm, and the ultrafiltration base membrane is one or more of a polyvinylidene fluoride ultrafiltration membrane, a polyether sulfone ultrafiltration membrane, a polysulfone ultrafiltration membrane and a polyimide ultrafiltration membrane. |
