Summary: In this study, chitosan/graphene oxide (CS/GO) nano-electrodes were fabricated for the efficient electrosorption of U(VI) from uranium-containing effluents. The CS/GO-4 electrode showed the best electrosorption performance for U(VI) due to its well-balanced meso-/micro-porous structure and superior conductivity. The isotherms and kinetics were fitted by Langmuir model. The maximum removal capacity for U(VI) reached 271.2 mg/g at 0.9 V, which was almost double compared to 0.0 V. The electrosorption-desorption cycles further demonstrated the potential application of CS/GO electrode materials for the removal of U(VI) from radioactive wastewater.

Summary: Polyaniline (PANI) was electrodeposited on porous biocarbon (CC) to fabricate a high-performance composite electrode (CC/PANI) for U(VI) electrosorption. The CC/PANI electrode showed high specific capacitance, excellent cyclic stability, and capacitive control characteristics. CC/PANI-2 exhibited the highest electrosorption capacity for U(VI) among various CC/PANI electrodes, reaching a maximum value of 282.2 mg/g at pH 4.0 and 0.9 V. The electrosorption mechanism for U(VI) removal is mainly ascribed to EDL and pseudocapacitive electrosorption, with possible contribution from U(VI) coordination by N atoms of CC/PANI. This work provides a strategy for the efficient treatment of radioactive nuclear wastewater.

Summary: The effectiveness of flow electrode capacitive deionization (FCDI) as a method to concentrate radioactive wastewater has been assessed for the first time in this study. The results showed that uranium (U) can accumulate into the electrolyte and on activated carbon in the flow electrode, with a removal efficiency of over 99% during each cycle. Analysis of XPS revealed the migration route and valence change of U in the flow electrode, explaining its high adsorption capacity in FCDI. Long-term experiments demonstrated that the low concentration feed water could be concentrated by 47 times, achieving a final concentration of 2843 mg L-1 U. Under optimized conditions, FCDI achieved a charge efficiency of 86% and a low energy consumption of 2.03 mg J(-1). Overall, FCDI shows promise as a method for treating radioactive wastewater, with high removal rate, excellent concentration effect, and low energy consumption.

Summary: This study aims to remove uranium ions from nuclear wastewater by electrosorption, using the complex of chitosan and phytic acid as the electrode material. The experimental results demonstrate that the introduction of phytic acid effectively enhances the adsorption capacity, selectivity, and reusability of chitosan. The study also reveals that the selective adsorption mechanism of uranium ions is related to the inner-sphere complexation between UO22+ and the O atom of the P=O group.

Summary: Phosphonate functionalized electrospun nanofibers have been found to effectively uptake U(VI), especially when functionalized with longer-chain phosphonate surfactants. The interaction between U(VI) and environmentally relevant ions was investigated, and it was observed that the presence of bicarbonate ions may increase the solubility of uranium. The study also revealed that U is bound to phosphonate groups as a monodentate inner sphere surface complex. This study provides valuable insights for the development of technologies for the detection and treatment of U in water.

Summary: Recently, a coupling approach of photocatalytic reduction and electro-adsorption (PEA) was proposed for uranium extraction. The PEA method, with an asymmetric electrode configuration of GP cathode and GT anode, combines complexation, electro-adsorption, and photocatalytic reduction to achieve enhanced U(VI) extraction. Compared to conventional photocatalytic reduction (PA) and electro-adsorption (EA) methods, the PEA method shows higher removal rate (91.3%) and faster kinetics rate (225% and 50%). Additionally, the PEA method also demonstrates improved reduction efficiency, selectivity, and reusability.

Summary: Two kinds of bio-based polyurethane coatings were prepared by in-situ polymerization using castor oil and liquefied starch as raw materials. The Castor-PU coating had a uniform and dense section morphology, while the Starch-PU coating had a certain proportion of microporous structure. The controlled-release property of Starch-PU was poorer compared to Castor-PU, possibly due to the presence of concentrated sulfuric acid and hydrophilic dispersant in the liquefied starch.

Summary: The corrosion behavior of Fe-60 and Fe-83 ribbons in 0.6 M NaCl was studied. Fe-60 exhibited a local corrosion mode and formed a stable passivation film with higher corrosion resistance, while Fe-83 showed a combination of local and global corrosion modes and had lower corrosion resistance. Controlling the precipitation of nanocrystalline phases and increasing the POx content in the passivation film significantly improved the corrosion resistance of Fe-based glassy alloys.
