Removal of iodine (I− and IO3−) from aqueous solutions using CoAl and NiAl layered double hydroxides

Cuprous Oxide-Based Cationic Hydrogel by the Integration of Enrichment and Immobilization of Radioiodine (I–, IO3–) in Aqueous Solution

“…Table S8 compared the K d values of iodine removal by different materials in different environments; the K d values of the first four materials to adsorb iodine in deionized (DI) water were higher than that of Cu 2 O@CH. But compared with the K d values of the CoAl and NiAl adsorbents prepared by Kang et al 55 for the treatment of iodine in the synthetic Ca-containing groundwater (SGW -2) and the real Hanford groundwater (HGW), it could be seen that the distribution coefficient of the Cu 2 O@CH was at a high level.…”

Smart intercalation and coordination strategy to construct stable ratiometric fluorescence nanoprobes for the detection of anthrax biomarker

“…In addition, the absorption peak of CO showed a slight blue shift and weakening at 1345–1355 cm −1 , suggesting that anionic L enters the interlayer of the lamellae via partial exchange with CO 3 2− . 57 Furthermore, the detailed bonding types were also studied using the high resolution XPS spectra of L@Mg-Al-Ln-LDH nanocomposites (Fig. S13 and 14†).…”

Iodine Removal from Carbonate-Containing Alkaline Liquids Using Strong Base Resins, Hybrid Resins, and Silver Precipitation

“…Liquid phase capture of iodine (as iodide or iodate) is less mature than vapor phase capture, but foundational knowledge is present. ,, The iodide or iodate can be removed through ion exchange, sorption, or precipitation as a low solubility phase (e.g., AgI, K sp = 8 × 10 –17 ). Materials demonstrated for iodine removal include MOF, Ag-based materials, ,− Bi-based materials, − resins (for iodide), − resins (for iodate), , membranes, and layered hydroxides. , However, in nearly all cases, only a single iodine species was the removal target, however, in practicality, these two species commonly coexist with one another. As both I – and IO 3 – are generated in CS, the removal of both must be considered in any such treatment process.…”
