Patent number: 12157092Abstract: A method for creating a seawater desalination reverse osmosis membrane that excels in both water flux and boron removal. The method utilizes the abundant and reactive amino groups of carbon nitride in an interfacial polymerization reaction to enhance the membrane's structure. The unique pore and interlayer structure of carbon nitride is employed to modify the membrane's hydrophilicity, roughness, and interlayer structure, thereby boosting its water flux and boron removal capabilities. Additionally, the carbon nitride solution demonstrates exceptional dispersion properties. Its hydrophilic amino groups react with the organic phase monomer trimesoyl chloride during polymerization, ensuring an even distribution in the polyamide layer without any agglomeration. The evenly dispersed m-phenylenediamine and carbon nitride solution, along with sodium hydroxide in the aqueous phase, quicken the acylation reaction rate.Type: GrantFiled: January 23, 2024Date of Patent: December 3, 2024Assignee: CHINA AGRICULTURAL UNIVERSITYInventors: Changwei Zhao, Junliang Huang
