ABSTRACT Achieving efficient separation of thorium and uranium is one the main technical challenges for nuclear fuel cycle thorium‐based molten salt reactors. In this work, scalar relativistic density functional theory (DFT) calculations were adopted to deeply unravel complexation behaviors selectivity Th 4+ /UO 2 2+ with four amide ligands L A , B C D containing N ‐heterocycles. The analyses dihedral angle, bond length, WBIs, IGMH, ETS‐NOCV indicated that more likely coordinate in gas phase...
Unraveling uranium complexes has become a popular study topic in recent years to address the problem of spent fuel treatment. An important and promising investigation is enantiomer separation chiral organophosphorus pesticides (OPs) via uranyl‐containing receptors. Among them, malaoxon (MLX), as OP with high toxicity good selectivity, controversial because different differences caused by R S configurations target non‐target organisms. Therefore, it crucial explore effective methods for...
An efficient ionic liquid-based microwave-assisted (IL-MAE) method has been developed for extraction of dehydrocavidine from Corydalis saxicola Bunting (C. saxicola) subsequent rapid analysis by high-performance liquid chromatography (HPLC). The yield reached 9.446 mg g−1 within 10 min under the optimum IL-MAE conditions (1.5 mol L−1 [hmim]Br as solvent, liquid-to-solid ratio 20:1 (mL:g), and temperature 70°C). Compared with conventional procedures, proposed many advantages, example high...
Abstract The identification and separation of chiral pesticides R/S‐profenofos are great significance due to different biological toxicity isomers. In the study, we designed two novel ligands: (2,2′:6′,2″‐terpyridin)‐6‐yl(5‐methoxy‐1 H ‐pyrazol‐1‐yl) methanethione (TMMT) methanone (TMMO), taking them as ligands coordinated with uranyl, complexes [Uranyl‐TMMT] 2+ [Uranyl‐TMMO] receptors were successfully constructed. complexation enantioselectivity towards guests systematically unraveled...
To find new adsorbents for uranyl ions, the density functional theory (DFT) was adopted to design a series of ligands containing an anthracene and two five‐membered heterocycles with nitrogen family nonmetal elements (N, P, As) or oxygen (O, S, Se, Te), example, N,N′‐bis(2‐five‐membered heterocyclidene)‐1,8‐anthradiamines (BFHADAs). Then ions were coordinated BFHADAs generate five coordination complexes (Uranyl‐BFHADAs) heteroatoms N, As, Se Te, respectively. The heterocyclic rings...
In order to explore the enantioselectivity of new uranyl receptors chiral organophosphorus pesticides (COPs), we designed a novel ligand: 2‐(2‐hydroxy‐3‐methoxyphenyl)‐9‐(2‐hydroxyphenyl)thiopyrano[3,2‐ h ]thiochromene‐4,7‐dione (HTTDN) and constructed receptor Uranyl‐HTTDN by complexation HTTDN with uranyl. The COPs R / S ‐methamidophos ( ‐MAPs) ‐acephates ‐APs) were studied using density functional theory (DFT) method in this paper. results showed that vacuum toluene, could effectively...
The design of new uranyl‐ligands (uranyl‐Ls) is great significance for the separation and utilization uranium. In this paper, triazole group was introduced into uranyl‐salophen (uranyl‐S) to form asymmetric uranyl‐unilateral benzotriazole salophen (uranyl‐UBS); we further replaced two oxygen atoms uranyl‐UBS with sulfur generate thio‐salophen (uranyl‐UBTS) as a receptor. Then, comprehensively explored coordination models uranyl‐UBTS R/S‐triadimefons (R/S‐TDFs) enantiomers guests using...
Chiral fungicides R/S-metalaxyls(R/S-MTLs) and R/S-benalaxyls(R/S-BNLs) have different biotoxicity. It is very important to unravel molecular recognition enantiomeric separation of R/S-MTLs or R/S-BNLs. In this paper, we designed a novel asymmetric ligand: 5-methoxy-2-(4-methoxy-6"-(quinazolin-2-yl)-[2,2"−bipyridin]-6-yl)quinazoline(MMQBQ), further constructed new receptor Uranyl-MMQBQ by coordination MMQBQ with uranyl. The complexation guests R/S-BNLs were systematically studied using...
Chiral pesticides R/S‐ethiproles(R/S‐EPLs) have different biotoxicity. Due to the difficulty in separation of chiral sulphur enantiomers, it is great significance study selective recognition and enantiomers R/S‐ethiproles. Based on DFT method, we theoretically designed a novel asymmetrical ligand 4‐amino‐6‐(9‐[5‐hydroxy‐1 H ‐indol‐6‐yl]‐4,7‐dimethoxy‐1,10‐phenanthrolin‐2‐yl)‐1 ‐indol‐5‐ol (AHPIL). Then further constructed chiral‐at‐uranium complex, namely, Uranyl‐AHPIL, recognize separate...
A novel highly sensitive and specific electrochemical biosensor for detecting uranium based on Deoxyribozymes gold nanoparticles (AuNPs) is reported. In this work, AuNPs provide excellent signal transduction a large surface area immobilising numerous Deoxyribozymes, so low detection limit of 3.24 ng L−1 good linear relationship over the range 5.94–35.1 (r = 0.994) were obtained. The proposed presents high specificity selectivity not affected by other metal ions. Thus, protocol offers...
