“…S. S. Zyryanov et al attributed the most intense line at 529.6 eV in the XPS spectra to a chemical bond between oxygen and iodine during the investigation of a stainless-steel surface irradiated with protons in an iodine medium. They believe that one of the forms of iodine is also due to the O-I bond [ 22 ]. During the systematic investigation of the adsorption characteristics of radioiodine molecules on three kinds of low-index surfaces of Cu 2 O, the calculation was carried out using first principles density functional with periodic slab models.…”

Oxygen-containing functional groups tend to induce a strong interaction between solid adsorbents and iodine molecules, yet have not been systematically investigated. Herein, on the basis of a series of nitric acid-treated graphene oxide (GO) with different contents of oxygen functional groups for iodine adsorption, it was found that the iodine uptake capacity is proportionate to the oxygen content and the diversities of oxygen-containing groups. The density functional theory (DFT) calculation results also suggest that oxygen-containing groups result in strong interactions between iodine molecules and the adsorbents through a covalent bond-forming process, among which -OH groups possess a higher adsorption energy averagely. Such theoretical and experimental work deepens our understanding of the effects of oxygen functional groups on iodine adsorption and provides novel ideas for future design and synthesis of high-performance solid adsorbents for radioactive iodine.
