一种水相介导的疏松纳滤膜及其制备方法和应用
By using aqueous-phase-mediated reverse interfacial polymerization to form a uniform distribution of piperazine molecules in nanofiltration membranes, the problems of low flux and easy fouling of existing nanofiltration membranes are solved, enabling high-flux and high-rejection-rate treatment of sodium sulfate wastewater, extending membrane lifespan and reducing energy consumption.
