Metal organic frameworks as a versatile platform for the radioactive iodine capture: State of the art developments and future prospects

The increased amount of radioactive iodine and its isotopes in the environment has become an area of major concern. Involvement of iodine in metabolic activities and its biomagnification led to the accumulation of radioactive iodine at every step of the food chain as well as in the human body. In the human body, due to the direct involvement of iodine in the thyroid gland, it has become a frightening condition for scientists and researchers to capture and remove radioactive iodine from the environment. Various MOFs and MOF composites have been selected and synthesised to capture radioactive iodine. MOFs are considered a promising candidate because of their large surface area, structural stability, excellent porosity, ease of structural modification, and excellent adsorption capacity. This outlook provides the sources of radioactive iodine, past nuclear incidents, and various other techniques that were already being used. More specifically, this outlook focused on different types of MOFs and MOF composites along with their different approaches including capture and storing radioiodine.
