Abstract
The paper describes the structure and iodine adsorption performance of Ag+ ion-exchange 13X molecular sieve (Ag-13X) with a small Si/Al ratio. The Ag-13X has a high specific surface area (408 m2/g) and a large amount of micropore volume (0.18 cm3/g). The Ag-13X presents a strong affinity with I2 and CH3I. The I2 static adsorption capacity of the 26.7% Ag zeolite reached 700 mg/g. The adsorption capacities under 1‰ and 1% CH3I feeds are up to 104.4 mg/g and 131 mg/g, respectively. This study indicates the applicability of Ag-13X in severe nuclear accidents.
