Thin film composite (TFC) polyamide membranes have been widely applied for environmental applications, such as desalination and water reuse. The separation performance of TFC strongly depends on their nanovoid-containing roughness morphology. These nanovoids not only influence the effective filtration area but also regulate transport pathways through film. Although there ongoing debates formation mechanisms nanovoids, a nanofoaming theory─stipulating shaping morphology by nanobubbles degassed CO

Development of High Boron Removal Reverse Osmosis Membranes Based on the Preferential Adsorption-Diffusion Mechanism

Опубликована: Янв. 1, 2025

Reverse osmosis (RO) is the leading technology for obtaining drinking and irrigation water from seawater. While currently developed RO membranes achieve high salt rejection, they often fall short in effectively rejecting certain harmful constituents, such as boric acid. In this study, we a membrane that demonstrates boron removal performance, on basis of preferential adsorption-diffusion mechanism. The was constructed by grafting PEGDGE, material with higher affinity compared to boron. According mechanism, facilitates adsorption enhances its transport. preferentially adsorbed creates barrier hinders transport boron, thereby improving performance. not only achieved rejection rate at 91.37% but also maintained flux 45.71 L·m-2·h-1 under simulated seawater conditions, surpassing performance many previously reported membranes. Moreover, exhibited excellent long-term stability, critical factor practical applications. This work validates feasibility mechanism paves way development Furthermore, it addresses pressing challenges related resource safety quality.
