The graphene membrane will turn seawater into drinking water

The graphene oxide membrane has attracted the attention of scientists as a promising "candidate" for new water filtration technologies. It was developed at the National Graphene Institute at the University of Manchester and has already shown its effectiveness in filtering small nanoparticles, organic molecules and salts.

Previously, scientists found that when in water, graphene oxide membranes swell, as a result of which they begin to restrict the passage of salts dissolved in water through them until they are completely blocked. According to Professor Rahul Nair, it became possible to create membranes that "work" at the atomic level.

In brine, water molecules are always grouped around salt molecules. This enables tiny capillaries of graphene oxide membranes to block salts, passing only purified water, and at a high speed. This effect opens up prospects for the creation of new desalination technologies.
