Abstract

Radioactive gaseous iodine produced during the operation of nuclear reactors needs to be handled safely and efficiently. In this study, a nano-silver loading activated carbon fiber material Ag⁰@ACF was successfully synthesized by hydrothermal modification and in situ reduction methods, and then the Ag⁰@ACF material was characterized by SEM-EDS, XRD, BET, and XPS to evaluate the iodine adsorption performance of Ag⁰@ACF. The results show that the nano-silver particulates were uniformly loaded on the microporous activated carbon fiber material, the acquired Ag⁰@ACF composite exhibited high specific surface area and high reactivity. Its adsorption capacity of gaseous elemental iodine and methyl iodine reached 2.25 g/g and 0.48 g/g, respectively, the adsorption performance was increased by 2.5 times and 3.5 times in contrast to the blank activated carbon fiber material. With the increase of modifier concentration, the adsorption capacity of Ag⁰@ACF for gaseous iodine increases. The material still showed excellent adsorption performance (I₂: 2.30 g/g, CH₃I: 0.51 g/g) even at 130 ^oC. Through the analysis of material adsorption kinetics and mechanisms, the adsorption of Ag⁰@ACF materials for gaseous iodine is a chemical reaction between nano-silver and iodine to form a stable AgI, which is a stable chemical adsorption behavior. The highly reactive silver nanoparticles combined with the rich porous structure of activated carbon fiber materials can achieve rapid and efficient capture of gaseous iodine.

Key words: inorganic non-metallic materials radioactive gaseous iodine Ag⁰@ACF hydrothermal modification in situ self-reduction chemical adsorption
