Scientists from Queensland University of Technology (QUT) have developed a new material for cleaning up contaminated water from radioactive leaks and medical processes.
The team mixed titanate nanofiber and nanotubes into a powder that, it says, will clean the radioactive particles in a ton of water with a single gram, provided it’s properly distributed or filtered. The outsides of the nanotubes are coated with silver oxide nanocrystals to hold and fix radioactive iodine ions, even if the material becomes wet again.
"One gram of the nanofibers can effectively purify at least one ton of polluted water," Professor Zhu said in a statement. "This saves large amounts of dangerous water needing to be stored somewhere and also prevents the risk of contaminated products leaking into the soil."
