Removal of iodide Using Sn-zeolite under aqueous condition

In the world, electric power production of nuclear power plants (NPP) has been progressed for the past decades. Moreover, electric power production from NPP for continuous energy can be beneficial without producing green-house gas (CO₂). However, all radioactive wastes generated from NPP operation should be securely and safely managed during the nuclear fuel cycle. Especially, the waste includes radioisotope such as ¹²⁹I and ¹³¹I whose half-lives are t_1/2 = 1.57x10⁷ years and t_1/2 = 8.02 days, respectively. These iodine has harmful effects to humans through external and internal exposure which can bring burns to the skin and affect the thyroid gland. Therefore iodine needs to be removed safely. In this study, we used the HY zeolite and Sn ion for capturing iodide from solution waste. HY Zeolite is eco-friendly materials with having high sorption capacity, thermostability, ion exchange, and high pore size as porous material. And Sn ion has chemical interaction with iodide ion and economically affordable. Therefore, the objective of this study is to investigate the capturing radioactive iodine from solution using surface modified HY zeolite with Sn
