Across the globe, billions of people lack reliable access to clean drinking water. In the United States, cities like Flint, Michigan and Newark, New Jersey made national news headlines for the hazardous levels of toxic lead contamination in their drinking water. This is such a pressing issue that the U.S. Department of Energy lists “water security” as one of its grand challenges. To meet this need, many scientists aim to create cheaper and more efficient water purification technologies.
A porous carbon-based honeycomb structure called graphene oxide (GO) may just be the solution. Researchers at Pacific Northwest National Laboratory (PNNL) discovered a way to increase GO’s ability to remove toxic metal ions from water. The study, featured in JACS Au, provides a framework for the design and implementation of GO-based water purification technologies.
