Scalable Ti3C2Tx MXene interlayered forward Osmosis Membranes for water purification and recovery of organic solvents


Abstract image

The development of layers of nanosheets between the substrate and the polyamide layer has attracted a great deal of attention to improve the performance of the thin film composite membranes. However, membrane size is limited by current fabrication methods such as vacuum filtration. Here is a high quality MXene (Ti3G2Tx) The Osmosis (FO) membrane of the polylaide advancement is made on nylon substrates based on MXene’s subtle and large-scale brush coating. The prepared FO membrane shows a high water permeability of 31.8 l m–2 T.–1 And a low specific salt flow of 0.27 g l–1 Using 2.0 mol L–1 Sodium chloride as a drawing solution. This includes adjusting the properties of the substrate and the polyamide layer with the MXene coating, as well as simplifying the process of transporting water between the interlayer distances between the Ti.3G2Tx. The membrane also has a good organic solvent-promoting osmosis effect, with a high ethanol flow of 9.5 l m–2 T.–1 And a low specific salt flow of 0.4 g l–1 Using 2.0 mol L–1 Lithium chloride as a drawing solution. Moreover, MXene’s layered fossa membrane demonstrates its potential use in real sea water treatment and industrial textile wastewater treatment. This work is an effective approach for better performance of the interconnected FO membranes of nanomaterials, both for desalination and restoration of organic solvents.
