| titleOfInvention | Mixed matrix cation exchange membrane based on metal organic framework compound and preparation method thereof |
| abstract | The invention discloses a mixed matrix cation exchange membrane based on a metal organic framework compound and a preparation method thereof, belonging to the technical field of membrane separation. The mixed matrix cation exchange membrane is prepared by taking sulfonated polyether sulfone as a membrane matrix material, taking hydrophilic MIL-101, UIO-66, ZIF-8, modified chitosan, sodium alginate and chitin as additive substances and finally obtaining the mixed matrix cation exchange membrane by a blending method. The invention provides a simple film forming method, the obtained mixed matrix cation exchange membrane has improved porosity and good hydrophilicity, the addition of the organic metal framework compound improves the ion exchange performance of the membrane, reduces the membrane resistance and improves the anti-pollution performance of the membrane, and the sulfonated polyether sulfone is taken as the matrix to enhance the mechanical strength, the ion exchange performance and the thermal stability of the membrane. |
