Harvesting uranium from seawater

The video discusses the presence of uranium in the Earth's oceans, highlighting its concentration and total amount. Traditional methods of uranium extraction involve using ligands braided into plastic fiber mats submerged in the sea. A new sustainable method using chitin from crab and shrimp shells offers a biodegradable alternative for uranium extraction.

Describe the new material found for capturing uranal ions.
