放射性CH_(3)I捕集预处理技术研究进展

Advances in Pre-capture Treatment Technology for Radioactive Methyl Iodide

相比于分子碘,通过吸附法捕集甲基碘是极具挑战的。目前,对于放射性甲基碘各国研究人员主要围绕两条技术路线展开攻关:开发银含量低,对放射性碘具有高吸附特性的固体多孔材料;开发捕集预处理技术对甲基碘进行分解或转化,以获得容易处理的放射性碘形式。文章首次对甲基碘捕集预处理技术发展情况进行梳理,并分析了相关技术下一步的研究重点,对相关研究人员具有重要的参考价值。

Compared to molecular iodine,the capture of methyl iodide by adsorption is extremely challenging.For radioactive methyl iodide,researchers in various countries are currently focusing on two main technical routes:the development of solid porous materials with low silver content and high adsorption properties for radioactive iodine;and the development of capture pretreatment technologies for the decomposition or conversion of methyl iodide in order to obtain an easily treatable form of radioactive iodine.This paper provides the first overview of the development of methyl iodide capture pre-treatment technologies and analyses the next research priorities for related technologies,which is an important reference value for relevant researchers.
