Nuclear power provides a chance for the decarbonization of global energy-related emissions. However, spent fuel produced by nuclear reactors contains various radionuclides, which require further disposal and treatment. Therefore, enrichment separation radionuclides are great significance recycling utilization resources. Organic polymer materials have attracted attention due to their excellent physicochemical properties rapid kinetics, high adsorption capacity, selectivity, diverse functionalization. This review an overview use pristine polymers, functionalized polymer-based composites highly efficient different kinds (i.e., U, Tc, I). The synthesis strategy, ability, related mechanism comprehensively summarized. structure–property relationships in that underpin outstanding environmental remediation performance also illustrated. Finally, challenges perspectives future radionuclide legacy waste management reasonably proposed, aiming design functional polymers task-specific applications.

Abstract Zeolitic imidazolate framework‐67 (ZIF‐67) membranes hold great promise in efficiently separating propene/propane mixtures. However, achieving highly permselective ZIF‐67 remains challenging due to unruly crystal nucleation and poor grain boundary structure. Herein, a magnetic‐field‐driven approach is reported fabricating high‐quality on anodized aluminum oxide substrates at room temperature. The presence of magnetic field increases the rates by shortening induction period, facilitates orderly rapid migration Co 2+ ions, optimizes crystallites substrate, inhibits excessive growth grains. These factors collectively contribute improving structure suppressing inter‐grain defects MOF membranes. resulting membranes, with thickness less than 480 nm, exhibit superior propylene/propane separation performance, featuring factor 135 propylene permeance 2.3 × 10 −8 mol m −2 s −1 Pa . expected greatly promote development for efficient energy‐saving separations.

Posttreatment of pristine metal–organic frameworks (MOFs) with suitable vapor may be an effective way to regulate their structures and properties but has been less explored. Herein, we report interesting example in which a crystalline nonporous Eu(III)-MOF was transferred porous amorphous MOF (aMOF) via iodine adsorption–desorption posttreatment, the resulting aMOF showed improved turn-on sensing respect Ag+ ions. The Eu-MOF, namely, Eu-IPDA, assembled from Eu(III) 4,4′-{4-[4-(1H-imidazol-1-yl)phenyl]pyridine-2,6-diyl}dibenzoic acid (H2IPDA) exhibited two-dimensional (2D) coordination network based on one-dimensional secondary building blocks. close packing 2D networks gives rise three-dimensional supramolecular framework without any significant pores. Interestingly, Eu-IPDA could absorb molecules when crystals were placed at 85 °C, adsorption capacity 1.90 g/g, is comparable those many MOFs large BET surfaces. attributed strong interactions among molecule, carboxy group, N-containing group leads amorphization framework. After immersion iodine-loaded EtOH, approximately 89.7% removed, MOF, denoted as a-Eu-IPDA. In addition, remaining a-Eu-IPDA causes luminescent quenching fluorescence emission region center compared that Eu-IPDA. luminescence intensity water suspensions significantly enhanced ions added, detection limit 4.76 × 10–6 M, 1000 times It also anti-interference ability over common competitive metal potential sense natural bodies traditional Chinese medicine preparations. A mechanistic study between absorbed iodine, carboxylate N atoms all contribute performance

Heavy metal ion wastewater is a pressing and inescapable issue that closely related to human health ecological security due its toxicity, carcinogenicity, the unmanageable property of this type wastewater. Metal–Organic Frameworks (MOFs) are class crystalline nanoporous materials with flexible designability controllability, showing great potential in field adsorption purification heavy metals In Perspective, we first discuss harm different ions briefly expound virtues MOFs for pollutant adsorption. Then, mainly summarize recent advances construction metal-based (Zr-based, Zn-based, Co-based, Al-based, etc.) their research progress Furthermore, various types MOF additives can often be effectively applied by functional modification or other composition. Additionally, several commonly used kinetics isotherm models also detailed help an in-depth understanding mechanism. Finally, challenges opportunities additionally discussed, review may provide new insight water applications.
