Porous metal–organic frameworks (MOFs) have shown great potential as adsorbents for capturing radioiodine, a major fission product generated during the reprocessing of nuclear fuel. However, studies exploring correlation between structure MOFs and iodine uptake capacity remain notably rare. In this study, we introduce new strategy enhancing adsorption efficiency by strategically varying position functional groups on organic linkers. Employing ligand-functionalized UiO-67 MOFs, our findings reveal that ortho-amino substitution UiO-67-o-NH2, proximal to node dicarboxylate linker, markedly accelerates kinetics vapor in comparison meta-amino UiO-67-m-NH2, where amino are oriented away from node. contrast, UiO-67-m-NH2 exhibits higher 2.19 g/g, compared 1.91 g/g attributable its porosity. Furthermore, competitive I2/H2O study demonstrated UiO-67-o-NH2 faster selectivity presence water UiO-67-m-NH2. Additionally, crucial influence positional isomerism has been corroborated through Raman spectroscopy, X-ray photoelectron density theory calculations. These analyses nitrogen atom positioned at ortho site demonstrates stronger affinity molecules meta site, thereby improving kinetics.
