▶ Date: 2023. 09. 22(Fri)

▶ Time: 10:00 ~ 11:00AM

▶ Venue: Research Building I, #310

▶ Speaker: Dr. Saeha Chong(Pacific Northwest National Laboratory)

▶ Title: Solid Sorbents for Iodine Capture

▶ Abstract:

The presentation summarizes the synthesis methods, the loading capacities of iodine, and the properties of different solid sorbent materials developed for iodine capture. The sorbent materials includes metal (Ag, Bi, Cu, Sn)- polyacrylonitrile, Ag-xerogel, and Ag-faujasite. The chemisorption of iodine into sorbents and characterization of sorbents before and after iodine-loading will be discussed. The complete process of iodine capture using Ag-exchanged faujasite, the recovery of Ag for recyclability of iodine capture in a Na2S solution, and the immobilization of iodide from the elution process into an iodosodalite waste form  will be discussed.
