摘要	Wastewater treatment is one of the most challenging problems nowadays due to the presence of different solid pollutants like dyes, salts, and organic compounds. Graphene oxide (GO)-based membrane technology is a potential method to treat wastewater. Herein, we developed a novel cGO/MSG composite membrane by functionalizing GO nanosheets with monosodium glutamate (MSG) as a cross-linker with tailored interlayer spacing. Subsequently, the cGO/MSG membranes with varying thicknesses were utilized to achieve efficient separation of diverse salts and dyes. The as-synthesized cGO/MSG membrane showed high pure water permeance of 213 +/- 5 L m-2 h-1 bar-1. Such a membrane also showed excellent separation efficiency for dyes with high water permeance, i.e., methylene blue (100 +/- 1% and water permeance of 90 +/- 5 L m-2 h-1 bar-1) and even blue (99 +/- 1% and permeance 130 +/- 5 L m-2 h-1 bar-1). Moreover, the membranes exhibited excellent salt rejection properties, with rejection rates greater than 97% achieved for Pb(NO3)2 and Ni(NO3)2. Additionally, these membranes were also stable even in harsh conditions for a long time. We believe that this approach will help to develop different membranes in the future for desalination purposes.
