British researchers have developed a graphene oxide sieve designed to remove salt from seawater. The sieve may potentially be highly efficient in straining salt, which could help provide clean drinking water for millions of people who do not have a ready access to it. The researchers will now test the graphene sieve against current desalination membranes.
Graphene was first developed in a laboratory by University of Manchester researchers in 2004. The material was made up of carbon atoms in a hexagonal lattice. It was known to be as flexible as rubber but more conductive than copper. The material was also 200 times stronger than steel. Single-layer graphenes were proven difficult to mass produce through existing methods such as chemical vapour deposition, while current production schemes cost a fortune.
