Separation of minor actinides from highly acidic solutions using diglycolamide modified mesoporous silica synthesized via a novel ring-opening click reaction

Kai-Qiang Ma et al.

Summary: This paper describes the preparation of diglycolamide ligands functionalized mesoporous silica matrix for the rapid and efficient separation of trivalent minor actinides (MAs) from high-level liquid waste. The modified silica materials showed strong affinity for MAs in highly acidic solutions and demonstrated high separation efficiency within a short time. The binding mechanism involved direct coordination of MAs to a tridentate oxygen binding site. Additionally, selective separation of americium from curium was achieved through oxidation of Am(III) by sodium persulfate. The outstanding sorption performance of these materials makes them promising for the immobilization of trivalent actinides and the separation of americium from curium.

Interface-Constrained Layered Double Hydroxides for Stable Uranium Capture in Highly Acidic Industrial Wastewater

Peipei Yang et al.

Summary: The synergy of Mg-Co LDHs and DFNS in DFNS@Mg-Co LDH not only improves the acid endurance of Mg-Co LDH under harsh conditions but also increases the active sites of DFNS, resulting in a significant increase in U(VI) uptake capacity. The interface-constrained strategy provides LDH materials with durability under extremely acidic conditions and high adsorption capacity, showing promise for uranium capture from various water fields.

A non-polluting method for rapidly purifying uranium-containing wastewater and efficiently recovering uranium through electrochemical mineralization and oxidative roasting

Shao-yan Lv et al.

Summary: Iron-based materials are commonly used for treating uranium-containing wastewater, but the iron-uranium solids produced from this process can lead to persistent radioactive pollution. A new electrochemical mineralization method has been developed to recover uranium without generating pollutants, allowing for the effective separation and recovery of uranium and iron. This research provides a new strategy for uranium utilization and environmentally friendly treatment of uranium-containing wastewater.

Enhanced uranium removal from acidic wastewater by phosphonate-functionalized ordered mesoporous silica: Surface chemistry matters the most

Dimitrios A. Giannakoudakis et al.

Summary: The study presents a phosphonate functionalized ordered mesoporous silica as an efficient adsorbent for uranium removal in acidic conditions, achieving a high up-to-date capacity of 345 mg/g at pH = 4. The presence of other polyvalent cation does not affect the efficiency of adsorption, suggesting inner-sphere complex formation as the mechanism. The surface chemistry was found to be the key feature for the selective and stable removal of U(VI) species, based on spectroscopic validations of surface adsorbed U(VI).
