Scientists Make Breakthrough That Turns Seawater Into Drinking Water

MANCHESTER, England, Wednesday April 5, 2017 – The water surrounding the Caribbean already provides food and enjoyment for people living in the region and elsewhere. But now it could also be a source for unimaginable quantities of clean drinking water.
A UK-based team of scientists has created a graphene-based sieve capable of removing salt from seawater, a development that could aid the millions of people grappling with water shortages.
It has previously been difficult to manufacture graphene-based barriers on an industrial scale, but scientists from the University of Manchester, led by Dr Rahul Nair, solved some of the challenges by using a chemical derivative called graphene oxide. Its unusual properties, such as extraordinary tensile strength and electrical conductivity, have earmarked it as one of the most promising materials for future applications.
It has reportedly been difficult to produce large quantities of single-layer graphene using existing methods, and current production methods are costly, however.
Writing in the journal Nature Nanotechnology, Dr Nair nevertheless explained that graphene oxide can be produced by oxidation in the laboratory.
