[DK GreenRoots] NC State Develops Material To Remove Radioactive Contaminants From Drinking Water
"The new material – a combination of hemicellulose, a byproduct of forest materials, and chitosan, crustacean shells that have been crushed into a powder – not only absorbs water, but can actually extract contaminates, such as radioactive iodide, from the water itself. This material, which forms a solid foam, has applications beyond radioactive materials. Pawlak and fellow researchers found that it has the ability to remove heavy metals – such as arsenic – from water or salt from sea water to make clean drinking water."
Good to know. Too bad we have so many circumstances in which it will be useful.
