Innovative Membrane for Uranium Extraction Inspired by Nature
A team of researchers from Lanzhou University has pioneered a biomimetic membrane that can effectively extract uranium from seawater and salt lake water. This breakthrough offers promising solutions for wastewater treatment and the recovery of rare metals.
Published in Advanced Materials, the study highlights a two-dimensional membrane crafted through charge assembly and hydrogen bonding. Unlike traditional graphene oxide membranes, which often suffer structural damage, this new membrane mimics the resilience of plant cell walls, enhancing both stability and performance.
With mechanical strength increased by over twelve times compared to original graphene oxide membranes, the new design allows for precise uranyl ion separation. \"This achievement provides an efficient and sustainable method for extracting uranium from seawater,\" explains Li Zhan, the corresponding author.
Team member Tian Longlong adds that the membrane's high selectivity, stability, and low energy consumption make it a strong candidate for industrial-scale uranium recovery. The researchers are currently fine-tuning the membrane structure and production processes to expedite its application.
Lanzhou University emphasizes the technology's potential beyond uranium extraction, including water treatment, wastewater recycling, and energy recovery. This innovation could play a vital role in addressing global challenges like resource shortages, energy crises, and environmental pollution.
