Recent Advanced Development of Acid-Resistant Thin-Film Composite Nanofiltration Membrane Preparation and Separation Performance in Acidic Environments

Membrane filtration technology has attracted extensive attention in academia and industry due to its advantages of eco-friendliness related environmental protection high efficiency. Polyamide thin-film composite nanofiltration (PA TFC NF) membranes have been widely used their separation performance. Non-acid-resistant PA NF face tremendous challenges an acidic environment. Novel relatively acid-resistant polysulfonamide-based triazine-based developed, but these a serious trade-off terms permeability selectivity. Hence, how improve acid resistance performance environments is pivotal issue for the design preparation membranes. This review first highlights current strategies improving by regulating composition structure layer membrane performed manipulating optimizing construction method then summarizes performances environments, as studied recent years.
