Using graphene foam to filter toxins from drinking water

A team of researchers from MIT, the U.S. Department of Energy’s Argonne National Laboratory, and international institutions has devised a highly efficient method for removing uranium from drinking water. Applying an electric charge to graphene oxide foam, the researchers can capture uranium in solution, which precipitates out as a condensed solid crystal. The foam may be reused up to seven times without losing its electrochemical properties.
