How Water and Ions Interact with Graphene Oxide Films

Membranes are useful for separating materials from solutions, and graphene oxide (GO) membranes might prove superior to those made from polymers because of their greater durability and mechanical strength, especially in applications such as removing radioactive elements from contaminated groundwater. One group of scientists has used the U.S. Department of Energy’s Advanced Photon Source (APS), an Office of Science user facility at Argonne National Laboratory, to characterize how water and rare earth elements interact with GO. Their results are published in the journal Carbon. Read more…
