Abstract Uranium is a critical resource in the development of nuclear energy, and its extraction from natural seawater has been identified as potential solution to address uranium shortages. In this study, hierarchical meso‐/micro‐ porous metal‐organic framework functionalized with phytic acid (PA) microspheres (denoted H‐UiO‐66‐PA) are rationally synthesized for efficient extraction. This unique design allowed large adsorption capacity fast kinetics, making it promising material Due hierarchically structure, H‐UiO‐66‐NH 2 materials not only provide more sites grafting PA, thus enhance capacity, but also facilitate rapid diffusion uranyl ions which can quickly effectively access interior H‐UiO‐66‐PA adsorbent. Therefore, obtained achieve an impressive absorption efficiency 6.76 mg g −1 actual within 15 days. Meanwhile, possesses good five adsorption/desorption cycles. work proposes feasible strategy constructing functional MOFs removal.

The effect of seawater on the flotation sulfide minerals is a hot research topic at present. Using instead fresh water to separate lead-sulfur can save resources and reduce lime consumption, which has broad prospects in terms economic environmental protection. Many studies have shown that divalent calcium magnesium ions are hydrolyzed form hydroxyl complexes under alkaline pH values, affects separation ore. In this paper, galena pyrite was tested, mechanism analyzed. Compared with deionized water, lead grade concentrate increased from 57.40 60.20%. Meanwhile, recovery declined 68.66 61.17%, SI value 2.020 2.072. With addition SHMP, SS, EDTA, 2.072 2.609, 2.525, 2.287, respectively. Noteworthily, when EDTA excessive, Pb 69.60%, 3.050. Wettability analysis, zeta potential X-ray photoelectron spectroscopy, Fourier transform infrared density functional theory calculation, E-DLVO calculation verified microflotation results revealed action.

Emerging electrochemical uranium extraction from seawater offers a promising route for sustainable fuel supply nuclear reactor operation. In this work, we intentionally synthesized conjugated microporous polymer (CMP) with π-conjugated skeletons and permanent porosity, which was induced by in situ electropolymerization on flexible carbon cloths, followed postdecorating amidoxime groups to create functional materials (CMP-AO). Driven an extra asymmetrical alternating current extraction, the self-supporting binder-free electrode is exceptionally capable of selectively rapidly capturing U(VI) simulated solution, affording capacity ∼1806.4 mg/g without saturation. Experimental observation combination ex/in spectroscopy revealed that CMP-AO enabled surface selective binding sites (amidoxime groups) U(VI), electrocatalytic reduction (carbazole yield yellow precipitates (Na2O(UO3·H2O)x) via reversible electron transfer presence sodium electrolyte. Furthermore, integrating adsorption-electrocatalysis system achieved 18.8 real 21 days good antibiofouling abilities, validating its feasibility practical application.
