Graphene Invention Makes Seawater Drinkable in One Simple Step

Using a type of graphene called Graphair, scientists from Australia have created a water filter that can make highly polluted seawater drinkable after just one pass. The technology could be used to cheaply provide safe drinking water to regions of the world without access to it. “Almost a third of the world’s population, some 2.1 billion people, don’t have clean and safe drinking water,” said lead author Dong Han Seo. “As a result, millions – mostly children – die from diseases associated with inadequate water supply, sanitation and hygiene every year. In Graphair we’ve found a perfect filter for water purification. “It can replace the complex, time consuming and multi-stage processes currently needed with a single step.” Developed by researchers at the Commonwealth Scientific and Industrial Research Organisation (CSIRO), Graphair is a form of graphene made out of soybean oil.
