Iodine is a crucial element in various industries, but it is one of the least abundant nonmetallic elements on Earth. Although seawater holds around 70% of the world's iodine reserves, its low concentrations—approximately 60 ppb—make extraction challenging. Additionally, radioactive iodine, which is released during nuclear accidents, presents significant long-term risks to marine ecosystems and human health. Therefore, there is an urgent need for effective strategies to both extract iodine from seawater and address radioactive iodine pollution.
