Abstract

Abstract

To remove radioactive iodine from spent fuel reprocessing, in this study, 8% silver loaded mordenite was used as the adsorbent, and the dynamic adsorption method was used to study the effects of gas linear velocity, adsorption column height, humidity and NO₂volume fraction on the adsorption effect of gaseous iodine. The experiment results show that the gas linear velocity has little effect on the saturated adsorption capacity, and the mass transfer resistance of the adsorption column increases at lower gas linear velocity; The height of the adsorption column has little effect on the mass transfer resistance. With the increase of the height of the adsorption column, the saturated adsorption capacity increases to a certain extent; Humidity does not affect the adsorption effect; NO₂ can promote the adsorption effect; Yoon-Nelson model can well fit the adsorption process of iodine on 8% silver loaded mordenite adsorption column.
