Rightsizing nanochannels in reduced graphene oxide membranes by solvating for dye desalination
Membranes with high water permeance, near-zero rejection to inorganic salts (such as NaCl
and Na2SO4), and almost 100% rejection to organic dyes are of great interest for the dye
desalination (the separation of dyes and salts) of textile wastewater. Herein, we prepared
reduced graphene oxide membranes in a solvation state (S-rGO) with nanochannel sizes
rightly between the salt ions and dye molecules. The S-rGO membrane rejects> 99.0% of
Direct Red 80 (DR 80) and has almost zero rejection for Na2SO4. By contrast, conventional …
