Iodine is widely used as a disinfectant and antiseptic in medical settings, particularly for cleaning wounds and sterilizing skin before surgeries. It is a key component in povidone-iodine solutions, which are effective against bacteria, viruses, and fungi. In the food industry, iodine is used as a sanitizing agent for equipment and surfaces to prevent contamination. It also plays a critical role in water purification processes, where it helps eliminate harmful microorganisms in drinking water. Additionally, iodine is essential in the production of certain dyes, inks, and photographic chemicals. In agriculture, it is used as a feed supplement for livestock to prevent iodine deficiency. Its radioactive isotopes are utilized in medical imaging and cancer treatment, particularly in thyroid-related conditions.
