Abstract
A low-pressure high-flux hollow fiber nanofiltration (NF) membrane, and a preparation method and use thereof are provided. The low-pressure high-flux hollow fiber NF membrane includes a base membrane and a negatively-charged separation layer formed on a surface of the base membrane, where a material of the separation layer is a crosslinking product of a negatively-charged sulfonated polymer. The low-pressure high-flux hollow fiber NF membrane of the present disclosure solves the technical problem that the hollow fiber NF membranes in the prior art are difficult to have both high performance and low energy consumption.
