Recent advances of loose nanofiltration membranes for dye/salt separation
TL;DR: Loose nanofiltration (NF) is a promising method for the fractionation of dyes and salts due to its excellent selective separation performance as mentioned in this paper, which is a potential candidate that can realize the transformation and upgrading for efficient recovery and cyclic utilization of high value-added components (i.e., dyes, salts).
