Researchers from the home of graphene, the University of Manchester in England, have discovered — seemingly by chance — one of the most important properties of graphene yet: It’s impermeable to everything but water. It is the perfect water filter.
In an experiment, the University of Manchester researchers filled a metal container with a variety of liquids and gases and then covered it with a film of graphene oxide. Their most sensitive equipment was unable to register any molecules leaving the container, except water vapor. The graphene oxide filter even prevented helium gas from escaping, which is notoriously finicky.
In another experiment, Dr Nair & Co. sealed a bottle of vodka with the graphene filter. This allowed just the water to evaporate, effectively distilling it into super-vodka.

Interesting material, wonder if it could filter flouride ions out of my tap water.
and by the sound of it, if graphene oxide really is completely impermeable to everything except water, this new filter would make clean water out of anything. Sea water, gray water, sewage…
