摘要：
In this paper, a sensor based on a magnetic surface molecularly imprinted membrane (MMIP) was prepared for the highly sensitive and selective determination of acetaminophen (AP). Before the experiment, the appropriate functional monomers and solvents required for the polymer were screened, and the molecular electrostatic potentials (MEPs) were calculated by the DFT/B3LYP/6-31 + G method. MMIP with high recognition of AP was synthesized based on Fe3O4@SiO2nanoparticles (NPs) with excellent core-shell structure. Next, a carbon paste electrode (CPE) was filled with a piece of neodymium-iron-boron magnet to make magnetic electrode (MCPE), and MMIP/MCPE sensor was obtained by attaching a printed polymer to the surface of the electrode under the strong magnetic. Due to the stable molecular structure of the electrode surface, the sensor is highly effective and accurate for detection of AP using DPV. The DPV response of the sensor exhibited a linear dependence on the concentration of AP from 6 × 10−8 to 5 × 10−5 mol L−1 and 5 × 10−5 to 2 × 10−4 mol L−1, with a detection limit based on the lower linear range of 1.73 × 10−8 mol L−1(S/N = 3). When used for determination of AP in actual samples, the recovery of the sensor to the sample was 95.80–103.76%, and the RSD was 0.78%–3.05%. © 2019 Elsevier B.V.

摘要：
In order to explore the enantioselectivity of uranyl-salophens to chiral molecules, the newly designed receptors of Λ-type configuration sulfur/selenium-substituted uranyl-salophens with R/S-chiral δ-lactone were used to selectively coordinate and recognize a pair of enantiomers of RRS/SSR-3,5-dimethyl-2-(3-fluorophenyl)-2-morpholinols as guests based on the density functional theory calculations. The results indicated that the substituent effects of R/S-asymmetry sulfur/selenium-substituted uranyl-salophens significantly affected the structures and properties of coordination compounds, and the R-type receptors have higher enantioselectivity for the chiral guests than the S-type receptors both in vacuum and in solvents water, acetone and toluene except the R/S-selenium-substituted uranyl-salophen in water. © 2020, Akadémiai Kiadó, Budapest, Hungary.

摘要：
The design of new uranyl-ligands (uranyl-Ls) is of great significance for the separation and utilization of uranium. In this paper, the triazole group was introduced into uranyl-salophen (uranyl-S) to form new asymmetric uranyl-unilateral benzotriazole salophen (uranyl-UBS); we further replaced two oxygen atoms of uranyl-UBS with two sulfur atoms to generate uranyl-unilateral benzotriazole thio-salophen (uranyl-UBTS) as a new receptor. Then, we comprehensively explored coordination models of uranyl-UBS and uranyl-UBTS with R/S-triadimefons (R/S-TDFs) enantiomers as the guests using density functional theory calculations at the B3LYP//RECP/6-311G** level; we then investigated enantioselectivity recognition of the new receptors to the guests R/S-TDFs. The results indicated that the uranium atoms of the receptors uranyl-S, uranyl-UBS and uranyl-UBTS could coordinate with the carbonyl oxygens in guests R/S-TDFs to form complexes of guest-receptors R/S-TDFs-uranyl-Ls that exhibited two stable V-shaped structures with quite different properties. It was found that the coordination ability to the guests R/S-TDFs is uranyl-UBTS > uranyl-UBS > uranyl-S, while the enantioselectivity for the guests is uranyl-UBTS > uranyl-S > uranyl-UBS and, when the receptor is the same, R-TDF has stronger coordination ability than S-TDF. These results provide information and theoretical supports for the experiments of asymmetric uranyl-UBS with R/S-TDFs, and produce a reference for further exploring the coordination characteristics of asymmetric uranyl-salophen with the triazole derivatives. © 2020 John Wiley & Sons, Ltd.

摘要：
Bi, Fe, and Ti ternary co-doped ZrO2 (BFT-ZrO2) nanocomposites have been prepared by a sol-gel process and used as both adsorbent and matrix for the enrichment and determination of small molecules by surface-enhanced laser desorption/ionization time-of-flight mass spectrometry (SELDI-TOF MS). The BFT-ZrO2 nanocomposites not only can selectively enrich a wide variety of low-mass toxic pollutants but can also be used as an excellent matrix to enhance the laser desorption/ionization efficiency with low background noise and uniform co-crystalline film. Low limits of detection (LODs) (0.1 pg mL−1 for bisphenol A (BPA), 2 pg mL−1 for tetrabromobisphenol A (TBBPA), 0.1 pg mL−1 for alizarin (AZ), 0.001 pg mL−1for bisphenol S (BPS), 0.01 pg mL−1 for indigo blue (ID), 0.01 pg mL−1 for pentachlorophenol (PCP), 100 pg mL−1 for estradiol (E2), 0.001 pg mL−1 for cetyltrimethylammonium bromide (CTAB), 0.1 pg mL−1 for crystal violet (CV), 1 pg mL−1 for malachite green (MG), 0.01 pg mL−1 for rhodamine B (RhB), and 0.01 pg mL−1 for perfluorooctane sulfonate (PFOS) were achieved. The relative standard deviations (RSDs) of shot-to-shot are 9.4–24% and of sample-to-sample 5.2–17%. The BFT-ZrO2 matrix was successfully applied to the determination of TBBPA and BPA in tea samples. This method shows a new strategy for determination of toxic compounds in tea. [Figure not available: see fulltext.] © 2020, Springer-Verlag GmbH Austria, part of Springer Nature.

摘要：
To find new adsorbents for uranyl ions, the density functional theory (DFT) was adopted to design a series of new ligands containing an anthracene and two five-membered heterocycles with nitrogen family nonmetal elements (N, P, As) or oxygen family nonmetal elements (O, S, Se, Te), for example, ligands N,N′-bis(2-five-membered heterocyclidene)-1,8-anthradiamines (BFHADAs). Then the uranyl ions were coordinated with BFHADAs to generate five new coordination complexes (Uranyl-BFHADAs) with heteroatoms N, S, As, Se and Te, respectively. The five-membered heterocyclic rings of Uranyl-BFHADA with oxygen atoms were broken under the structural optimization and Uranyl-BFHADA with heterocyclic atoms P was not obtained. Several structures and property parameters of the ligands BFHADAs (containing heteroatoms N, S, As, Se and Te) and their uranyl complexes Uranyl-BFHADAs were theoretically investigated and analyzed. The results showed that uranyl ions could form stable coordination complexes with these five BFHADAs. The formed bonds between uranyl ions and the heteroatoms in BFHADAs were coordination bonds rather than other types of bonds. These results could provide insightful information and theoretical guidance for the coordination of uranyl with the atoms N, S, Se, As and Te in other ligands. © 2019 John Wiley & Sons, Ltd.

摘要：
A molecularly imprinted electrochemical sensor for the rapid detection of the anti-parasitic drug Secnidazole (SCZ) is reported. In this work, the build electrochemical sensor was based on a carbon paste electrode (CPE) modified with multi-wall carbon nanotubes (MWCNTs) and boron-embedded duplex molecularly imprinted composite membranes (B-DMICMs), that significantly increased the efficiency of the sensor for the detection of template molecule SCZ. Density functional theory (DFT) was employed to study the interactions between the template and monomers to select appropriate functional monomers for rational design of the B-DMICMs.The optimal experimental conditions were optimised for the factors affecting the performance of the sensor. Under the optimal conditions, the reduction peak currents of SCZ by differential pulse voltammetry increased linearly with SCZ concentration in the range from 3.0 × 10−4 to 1.0 × 1.0−6 mol L−1 and 1.0 × 1.0−6 to 1.91 × 10−8 mol L−1 with a detection limit of 1.72 × 10−8 mol L−1 for secnidazole, which is significantly lower than those in the currently used methods and in previous reports. This method offers low cost, sensitive and effective determination of SCZ and can potentially be used for detection of SCZ in pharmaceutical and biological samples with good precision and accuracy. © 2019, © 2019 Informa UK Limited, trading as Taylor & Francis Group.

摘要：
A dually responsive fluorescent probe for determination of U(IV) and mercury(II) ions was synthesized. The probe consists of a cytosine-rich hairpin DNA loaded with silver nanoclusters (DNA-AgNCs). The fluorescence of the AgNCs is found to be quenched by UO2(II) at pH 5.0and Hg(II) at pH 7.0due to combinedstatic and dynamic quenching. Under the optimal conditions, the greenfluorescence of the DNA-AgNCs, best measured at excitation/emission wavelengths of 420/525nm, decreases in the 4.0 to 75 pM UO2(II) concentration range, and in the 0.3 to 8.0nM Hg(II) concentration range. The respective detection limits are as low as 1.8 pM and 0.1nM. The method was successfully applied to the determination of UO2(II) and Hg(II) in (spiked) pond and taps waters and in soil extracts.

摘要：
In this paper, we report a method for the determination of uranium (VI) based on the using of a surface fluorescence sensor containing a europium (III) complex. The sensor was prepared by immobilizing the Eu(III)-salophen complex on a glass slide surface through Si–O covalent bonds. The sensor can generate strong surface fluorescence as a result of the Cation–Cation Interaction between U (VI) and Eu(III). We used this property to design a surface fluorescence sensing method to detect U (VI). Under suitable conditions, the linear range was 0.02–5nmolmL−1 and the detection limit was 8 × 10−3nmolmL−1. This method was successfully used in determine U (VI) in real samples with a recovery rate between 99.5 and 103.5%. © 2019, Akadémiai Kiadó, Budapest, Hungary.

摘要：
铀是一种重要的自然资源,在多个领域都有广泛的用途,所以检测铀也变得越来越有意义.建立了一种操作简单,价格低廉,灵敏度高的检测方法,首先将Salo-phen与铀酰结合成Uranyl-Salophen配合物,接着采用十二烷基硫酸钠(SDS)表面活性剂将配合物包裹,从而达到增敏检测U(VI)的目的.优化了时间、温度、SDS剂量、pH条件,在最优条件下荧光强度与铀的浓度范围在0.005～3.5 mol/mL下呈现良好的线性关系,在实际样品中检测铀的回收率在96％ ～103％.

摘要：
香豆素及其衍生物具有很强荧光性.香豆素类荧光探针广泛应用于药物开发、疾病监测、金属离子检测等.随着工业化的发展,越来越多的有毒金属离子存在于我们生活环境之中,如何快速有效地识别金属离子显得尤为重要.用4-甲基-8-甲酰基-7-羟基香豆素、2-氨甲基吡啶反应合成了一种能够识别Cr^3＋的新型荧光分子探针MFHC.当溶液为乙腈时该配体对Cr^3＋具有高度的选择性识别作用,并且当其他离子在高于Cr^3＋浓度5倍的情况下该配体仍具有较强的抗干扰能力.荧光滴定实验表明：主体与配体之间的配位比应为1∶1,检测限为1.19×10^-11μmol/L.
