Summary: The design of anion-scavenging materials with high charge density and accessible adsorption sites is crucial for the removal of anions, such as 99TcO4-, from radioactive nuclear waste. In this study, a cationic organic polymer called TrDCPN was synthesized to efficiently trap perrhenate (ReO4-), serving as a surrogate for 99Tc. The TrDCPN demonstrated excellent affinity towards ReO4- even in the presence of competitive anions, and it exhibited promising reusability for trapping ReO4-. The introduction of halogen in the synthetic cationic organic polymer effectively enhanced its adsorption capacity, making it a promising solution for removing radioactive pollutants from the environment.

Summary: Uranium removal by photocatalytic reduction is effectively achieved using a Z-scheme van der Waals heterojunction photocatalyst (SnS2COF) synthesized by combining covalent organic frameworks (COF) with semiconductor (SnS2). The SnS2COF heterojunction exhibits superior U (VI) reduction capacity in rare earth tailings wastewater due to wider light absorption range, more active sites, and higher electron-hole separation and transfer efficiency. Under photoexcitation, the heterojunction maintains high reducibility and avoids photocorrosion of SnS2. The organic-inorganic heterojunction design concept provides an alternative strategy to enhance photocatalytic performance.

Summary: A covalent organic framework (Tph-BT COF) with excellent photocatalytic activity is constructed by Schiff base reaction, and its mimetic oxidase and peroxidase activities are inversely regulated by single-stranded DNA (ssDNA). Under LED light irradiation, Tph-BT exhibits outstanding oxidase activity, which is inhibited by ssDNA with poly-thymidine (T) sequences, while its weak peroxidase activity is enhanced by ssDNA with poly-cytosine (C) sequences. The study also investigates the influence of base type, base length, and other factors on the activities of the two enzymes, revealing the mechanisms behind the regulation by ssDNA.

Summary: In order to ensure the long-term sustainable development of nuclear energy and prevent uranium pollution, there is an urgent need for new materials that can detect and separate uranium simultaneously. In this study, a new fluorescent covalent organic polymer (COP) named HT-COP-AO was synthesized and used as a fluorescent probe and absorbent for uranium detection and separation. The results showed that HT-COP-AO had a strong fluorescence quenching effect on uranium with a detection limit of 0.23 μM. It was found that uranium was coordinated with the amidoxime groups of HT-COP-AO through U-N and O = U = O bonds, leading to electron transfer and fluorescence quenching.

Summary: The isomerism of a covalent organic framework (COF) greatly affects its electrochemiluminescence (ECL) performance. In this study, two isomeric COFs, TFPB-BD(OMe)(2)-H and TAPB-BD(OMe)(2)-H, were synthesized based on different imine linkages and conversion to the quinoline structure. Despite having the same composition and similar structures, the two COFs exhibited significant differences in photoelectrochemical and ECL fields. TFPB-BD(OMe)(2)-H showed a superior ECL emission compared to TAPB-BD(OMe)(2)-H due to stronger polar interaction and enhanced electron interactions.

Summary: In this work, a portable analytical system based on point discharge chemical vapor generation atomic emission spectrometry (PD-CVG-AES) coupling with gold filament enrichment was designed. The highly sensitive analysis of Hg2+ indirectly realized the detection of ascorbic acid (AA). The measurement is based on the fact that Ag+ can decrease the concentration of Hg2+ by forming Ag-Hg amalgam in the presence of the reductant SnCl2, while AA can pre-reduce Ag+ to Ag0, leading to the generation of silver nanoparticles (Ag NPs). The developed novel analytical strategy broadens the application of microplasma-based AES and offers a higher level of sensitivity compared to current AA detection techniques.
