Graphene can be used in desalination as these membranes have the ability to block out sodium chloride. Due to its atomic thickness graphene membranes are able to filter dirty water in real time allowing it to be used to clean up chemical waste, oil spills and other contaminated water ways. Portable desalination units and water filters will be able to be dropped in remote areas, third world countries and suffering during natural disasters and tough times.
The exact same concept applies when creating air filtering membranes. Carbon emissions can become a thing of the past as these membranes are attached to exhaust pipes, factory chimneys plus many more….
