China-based researchers design new method to pre-enrich uranium in seawater using graphene oxide

Researchers at the Institute of Modern Physics (IMP) of the Chinese Academy of Sciences (CAS), in collaboration with teams from China’s Lanzhou University and Hebei University, have developed a graphene oxide-based method of pre-enriching uranium in seawater by membrane filtration.

In their study, the scientists fabricated a new type of glycine cross-linked composite graphene oxide (GO-Gly) membrane with good ion sieving properties, which can meet the demands of uranium pre-enrichment in seawater.
