Thin-film nanocomposite membrane incorporated by aminated MoS_(2)nanodots for Cl^(-)/SO_(4)^(2-)separationOA
Interfacial polymerization is the most preferred method to fabricate nanofiltration and reverse osmosis membranes in both academia and industry,while it is facing the challenge of high performance,especially in flux.Herein,we proposed a method to incorporate the amino-functionalized molybdenum disulfide(MoS_(2)–N)nanodots(NDs)in interfacial polymerization to tune the membrane structure,especially the water transport path to enhance membrane performance.MoS_(2)NDs have characteristics of high surface smoothness and low fluid diffusion resistance.The MoS_(2)NDs incorporated thin-film nanocomposite(TFN)membrane can reduce the water friction resistance in membrane matrix,thus accelerating the transmembrane transfer of water molecules.The morphology and properties of the NDs and membranes were characterized.The functionalization degree and concentration of MoS_(2)–N NDs in the membrane were tuned.At optimum conditions,the MoS_(2)–N NDs incorporated TFN membrane exhibited a pure water permeance of 24.98 LMH/bar,2.5-fold that of the control membrane,with a high Cl^(-)/SO_(4)^(2-)selectivity of 119.2(NaCl and Na_(2)SO_(4))and a good long-term stability.
