Synthesis of iodine-sorbent with applicability in decontamination of the gaseous phase of the dissolution stage of Fission-Molly production

Abstract

To produce the Technetium-99 isotope from Molybdenum-99 radioactive decay and purify the product of small-scale acidic target dissolution, the gaseous Iodine impurity has to be reduced to AN acceptable level. Solid adsorbents are used for this reason. One of the best adsorbents is based on Silver-Exchanged Mordenite. In this research, the synthesis procedure and characteristics of synthesized adsorbent have been discussed. To prepare solid adsorbent, spheric mordenite hallow crystals of about 10 micrometers and the Si/Al ratio of 5.2 were synthesized and granulated using a binding agent, stabilizer, and foaming agent. Prepared granules were silver exchanged. The silver content of the end product was evaluated 8.1 weight percent. Results from gaseous Iodine adsorption showed that 99.2 percent of passing Iodine was adsorbed.
