| titleOfInvention | A kind of composite nanofiltration boron removal membrane and preparation method thereof |
| abstract | The invention provides a composite nanofiltration boron removal membrane and a preparation method thereof, belonging to the technical field of polymer materials. The composite nanofiltration membrane for boron removal is PDADMAC/PSS‑X‑CSPES/PES, wherein X is the number of layers of the double-layer electrostatic self-assembly functional layer PDADMAC/PSS, and the value of X ranges from 4‑7. The lower part includes the PDADMAC/PSS functional layer, the CSPES composite layer, the PES support layer and the non-woven fabric. The invention also provides a preparation method of the composite nanofiltration membrane for removing boron. The composite nanofiltration boron removal membrane of the present invention has relatively excellent separation performance for the treatment of high-concentration boron-containing wastewater. |
