| titleOfInvention | High-strength hydrophilic nanofiltration membrane, preparation method thereof and application thereof in protein solution desalination process |
| abstract | The invention relates to a high-strength hydrophilic nanofiltration membrane, a preparation method thereof and application thereof in a protein solution desalination process, and belongs to the technical field of membrane materials. The nanofiltration membrane provided by the invention utilizes the modifier containing polyhydroxy to form bonding with-SiO-of montmorillonite to form a cross-linked network structure, and meanwhile, the modifier also has hydrophobic genes and can form a better compatible structure with a base membrane, so that the bonding force between the montmorillonite and the base membrane is improved; because the montmorillonite has better ion exchange performance, when the nanofiltration membrane is applied to the protein solution desalination process, the nanofiltration membrane has better interception performance and pollution resistance to protein due to the hydrophilicity of the membrane, and has higher transmittance to inorganic salt due to the ion exchange performance of the montmorillonite. |
