Iodine is widely used as a disinfectant and antiseptic in medical settings, particularly for cleaning wounds and sterilizing skin before surgeries. It is effective in killing bacteria, viruses, and fungi, making it a key component in products like povidone-iodine solutions. In water treatment, iodine is employed to purify drinking water, especially in emergency situations or outdoor activities, by eliminating harmful microorganisms. Additionally, it plays a crucial role in the production of contrast agents for X-ray imaging, enhancing the visibility of internal organs and tissues. Iodine is also essential in the manufacturing of certain dyes, pigments, and pharmaceuticals, contributing to various industrial and medical applications.
