| titleOfInvention | A kind of high flux nanofiltration membrane, its preparation method and application |
| abstract | The invention discloses a high-flux nanofiltration membrane, a preparation method and application thereof. The preparation method includes: arranging a cellulose nanofiber layer on a microfiltration membrane support layer to prepare a cellulose nanofiber/microfiltration membrane composite bottom membrane; The aqueous phase-oil phase interface of the aqueous solution of amine monomer and salt and the organic solution comprising polybasic acid chloride, and making the polyamine monomer and polybasic acid chloride carry out interfacial polymerization reaction at the interface, so that the cellulose nano- A polyamide ultra-thin separation layer is formed on the surface of the fiber/microfiltration membrane composite bottom membrane, and then annealed to obtain a high-flux nanofiltration membrane. The high-flux nanofiltration membrane of the present invention improves the wettability and uniformity of pore size distribution of the traditional bottom membrane, and also solves the problem of biological toxicity caused by chromium hydroxide nanofibers or carbon nanotubes in the past. , High salt interception performance reduces the energy consumption cost of desalination, and has industrial application value. |
