  • Publication number: 20200398227
    Abstract: The present invention relates to a dye-salt separation membrane and a preparation method thereof. The method includes the following steps: firstly pouring an aqueous phase solution containing tannic acid and anhydrous piperazine on a surface of a polysulfone-based ultrafiltration base membrane at a mass ratio of the tannic acid to the anhydrous piperazine of 1:2 to 2:1, followed by complete infiltration, and draining the aqueous phase solution; and then pouring an organic phase solution of trimesoyl chloride on the surface of the base membrane, and draining the organic phase solution to obtain the dye-salt separation membrane. The method of the present invention is simple and easy to implement, and the dye-salt separation membrane prepared by the method has a relatively high solution permeability, an efficient dye retention and permeability of inorganic salts, thereby achieving an excellent dye-salt separation effect.

  • Patent number: 10143972
    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.
