  • Publication number: 20220135722
    Abstract: The present disclosure relates to a conjugated polyelectrolyte-grafted membrane, which is obtained by fixing a conjugated polyelectrolyte (CPE) capable of generating active oxygen under visible light irradiation to a membrane through crosslinking, and can remove contaminants in water, while reducing bio-fouling on the surface of the membrane, by generating active oxygen through a photocatalytic reaction of the conjugated polyelectrolyte (CPE), as well as to a method for manufacturing the same. The method for manufacturing a conjugated polyelectrolyte-grafted membrane includes the steps of: preparing a conjugated polyelectrolyte (CPE); coating a conjugated polyelectrolyte (CPE) on the surface of a membrane; and carrying out crosslinking of the conjugated polyelectrolyte (CPE) with the surface of the membrane.

  • Patent number: 9295974
    Abstract: The present disclosure relates to a floating type adsorbent for removal of phosphate that can effectively remove phosphate from aqueous phase through reaction between an amine function attached on the surface of a sponge and phosphate. This adsorbent can be regenerated by desorbing the adsorbed phosphate, a method for fabricating same and a method for regeneration the floating type adsorbent for removal of phosphate. The floating type adsorbent for removal of phosphate according to the present disclosure is fabricated by immersing a sponge in a mixture solution of an amine precursor and anhydrous toluene to form an amine function on the surface of the sponge. The amine precursor may be 3-aminopropyltriethoxysilane (APTES) and the APTES and the anhydrous toluene may be mixed at a volume ratio of 0.5-1:1.
