Chinese scientists develop biomimetic membrane for uranium extraction

Chinese researchers have developed a biomimetic membrane capable of efficiently extracting uranium from seawater and salt lakes, marking a breakthrough in wastewater treatment and rare metal recovery. This is reported by CGTN, a partner of TV BRICS.

The study by Lanzhou University introduces a two-dimensional membrane constructed using charge assembly and hydrogen bonding. This innovative approach ensures precise separation of uranyl ions, a crucial resource for the nuclear industry.

To address uranium shortages, the researchers combined graphene oxide with engineered bacteria, creating a durable and dense membrane that resists structural damage under high pressure. The new material is 12 times stronger than traditional graphene oxide membranes and offers high selectivity, stability, and low energy consumption.

This sustainable extraction method could accelerate the industrialisation of uranium recovery, with broader applications in water purification, wastewater recycling, and energy recovery, the experts claim. Researchers are now refining the membrane’s design for large-scale production to support global resource sustainability.
