Water desalination using a graphene-oxide membrane

Scientists from the University of Manchester have successfully developed a graphene-oxide, laminate membrane capable of removing up to 97% of NaCl ions from salt-water. Their findings, published in Nature Nanotechnology, demonstrate a method for modifying the interlayer spacing between graphene-oxide sheets for “tunable ion sieving”.

Their research also corresponds well with our own work at the Micro & Nano Flows for Engineering Group. Dr Matthew Borg and Professor Jason Reese have recently published an article in the MRS Bulletin of an overview of their work in multiscale modelling of water transport through high aspect-ratio carbon nanotubes. Both articles highlight some important applications of micro and nanoscale fluid research, namely providing fresh drinking water for water-scarce areas of the world.
