Using graphene foam to filter toxins from drinking water

Using graphene foam to filter toxins from drinking water

Imagine a world where clean drinking water is accessible to all, thanks to the wonders of graphene foam. This revolutionary material is not only lightweight and durable, but also capable of filtering out harmful toxins, transforming the way we approach water purification.

Uranium pollution

Leaching into water resources from mining operations, nuclear waste sites, or from natural subterranean deposits, the element can now be found flowing out of taps worldwide

Potential Applications

In the future, instead of a passive water filter, we could be using a smart filter powered by clean electricity that turns on electrolytic action which could extract multiple toxic metals, tell you when to regenerate the filter, and give you quality assurance about the water you’re drinking.”

Researchers from Argonne National Laboratory, Taiwan’s National Chiao Tung University, and the University of Tokyo also participated in the research.

A paper describing this work was published in this week Advanced Materials. The two first co-authors are Helal and Chao Wang, a postdoc at MIT during the study who is now with the School of Materials Science and Engineering at Tongji University, Shanghai.

Targeting the contaminant

Field testing from the U.S. Geological Service and the Environmental Protection Agency (EPA) has revealed unhealthy levels of uranium moving into reservoirs and aquifers from natural rock sources in the northeastern United States, from ponds and pits storing old nuclear weapons and fuel in places like Hanford, Washington, and from mining activities located in many western states
