  7. Abstract:
  8. Graphene is pure carbon in the form of a very thin, nearly transparent sheet, one atom thick. It is remarkably strong for its very low weight. Graphene is a novel particle that can improve adsorption properties. We use graphene for Iodine gas adsorption. Iodine-131 (usually in the chemical form of iodide) is a component of nuclear fallout, and is particularly dangerous owing to the thyroid gland's propensity to concentrate ingested iodine, where it is kept for periods longer than this isotope's radiological half-life of eight days. For this reason, if people are expected to be exposed to a significant amount of environmental radioactive iodine (iodine-131 in fallout), they may be instructed to take non-radioactive potassium iodide tablets. In this thesis we focused on evaluating Graphene for better adsorption. We synthesized Cu/Graphene and Ag/GRaphene nanocomposites by supercritical method for the first time in the world. Then we characterized it and adsorbed Iodine on it. Iodine adsorption on Graphene is novel too. Different analysis showed high amount of Iodine in nanocomposites structure. At least we recommend using these naanocomposites to eliminating Iodine from invironment
