Thorium is a promising nuclear fuel; however, even small amount in wastewater can cause significant radioactive pollution. Therefore, it urgent to develop effective adsorbents for the efficient removal of thorium solve this problem. Herein, phytic acid modification carboxylated Zirconium-based metal-organic framework materials (UiO-66-COOH-PA) has been obtained by rapid high-temperature carbonization, which exhibits excellent performance removing (IV) acidic aqueous solutions. The maximum adsorption capacity UiO-66-COOH-PA-2 (with 40% mass ratio acid) solution reaches 315.5 mg/g at pH 4, more than twice that unmodified Zr-based metal organic (MOF) material. kinetics UiO-66-COOH-PA on analyzed using two different isothermal models, Langmuir and Freundlich isotherm models. It turns out model suitable data. process dynamic equilibrium very quickly, while dynamics follows pseudo-second-order kinetic model. low values indicates material containing phosphorus especially systems. also selectivity (up 90.2%) Th(IV) presence several coexisting rare-earth ions. Overall, integration phosphorus-modified Zr-MOFs represents advancement technology, offering pathway toward management waste liquid.

Metal phosphonate frameworks (MPFs) consisting of tetravalent metal ions and aryl-phosphonate ligands feature a large affinity for actinides excellent stabilities in harsh aqueous environments. However, it remains elusive how the crystallinity MPFs influences their performance actinide separation. To this end, we prepared new category porous, ultrastable MPF with different crystallinities uranyl transuranium The results demonstrated that crystalline was generally better adsorbent than amorphous counterpart ranked as top-performing one plutonium strong acidic solutions. A plausible sequestration mechanism unveiled by using powder X-ray diffraction tandem vibrational spectroscopy, thermogravimetry, elemental analysis.

Abstract Thorium (Th), as a promising nuclear fuel, can cause serious radioactive contamination even in small amount wastewater. Therefore, it is urgent to develop effective adsorbents for the removal of thorium. Herein, phytic acid modification carboxylated zirconium based on metal-organic framework (UIO-66-COOH-PA) was obtained by rapid high-temperature carbonization, which exhibited excellent performance removing Th (IV) acidic solutions. The maximum adsorption capacity UIO-COOH-PA-2 (with mass ratio 40%) reached 315.5 mg/g at pH 4, more than twice that unmodified Zr-based MOF material (151.2 mg/g). thorium process dynamic equilibrium quickly different temperatures. Freundlich model fitted kinetics UIO-COOH-PA better and its dynamics followed pseudo-second-order kinetic model. low values indicated materials containing phosphorus were suitable especially systems. It also selectivity (up 90.2%) presence many coexisting rare-earth ions. These results will provide new strategy design efficient from wastewater environments.
