Summary for Patent: 10,143,972
| Title: | Ultrafiltration membrane and a preparation method thereof |
| Abstract: | The present invention provides an ultrafiltration membrane comprising a sulfone polymer membrane matrix with pores and an organic polymer sealing layer, wherein the pores are filled with nanoadsorbents. The present invention further provides a method for preparing the ultrafiltration membrane, which includes the following steps: (1) synthesizing nanoadsorbents; (2) preparing the sulfone polymer membrane matrix by immersion-precipitation phase inversion; and (3) immobilizing nanoadsorbents in the pores of the sulfone polymer membrane matrix by reverse filling, then sealing the pores with organic polymers to form a multifunctional ultrafiltration membrane. In the present invention, colloidal gold, polyethylene glycol molecules and Pb(II) ions (and so forth) are utilized as models of viruses, macromolecular organic pollutants, and small molecular pollutants, respectively. It is shown that the multifunctional ultrafiltration membrane allows for removal of multiple pollutants from water and can simultaneously remove multiple pollutants under low pressure. |
