Organic Solvent Permeation through Negatively Charged Graphene Oxide Membranes

Graphene oxide (GO) has emerged as a promising membrane material for organic solvent nanofiltration. This study aims to understand the permeation behaviors of five polar organic solvents [namely, methanol, isopropyl alcohol (IPA), dimethyl sulfoxide (DMSO), acetone, and methyl tert-butyl ether (MTBE)] through negatively charged GO membranes, benchmarked against that of water. Among the solvents studied,…
