Capture of Iodine in Vapor and Solution Phases by a Th-Based Metal–Organic Framework

Abstract

The efficient capture of radioactive iodine is of paramount importance due to its harmfulness. In this work, a new Thbased metal−organic framework (ECUT-Th-11) for iodine capture was reported. ECUT-Th-11 exhibited a relatively high capacity of capturing vapor iodine (2.03 g/g). Besides, the maximal adsorption capacity of iodine in a cyclohexane solution reaches 258.03 mg/g. All of the results demonstrated that ECUT-Th-11 could be a candidate material for the effective removal of waste iodine.
