Zinc is an essential trace metal element in the human body, but it also constitutes a variety of proteins body important elements necessary; this plays role physiological metabolism. Disturbances metabolism zinc ions can significantly threaten health, especially neurological diseases. Therefore, developing rapid and straightforward method for determining important. Fluorescent probe technology has been widely used detecting labeling ions. Among many fluorescent probes, rhodamine derivative...

Abstract In this study, the intermediates of photocatalytic degradation tetracycline hydrochloride (TC‐HCl) were analyzed by high performance liquid chromatography‐mass spectrometry. The doping polypyrrole (PPy) and carbon nanotubes (CNTs) increased reaction rate TC‐HCl ZnO. prepared ZnO has a large specific surface area, which can improve adsorption performance. introduction PPy CNTs promote electron transfer reduce recombination photogenerated hole pairs in composite material...

Using an ultrasound-assisted chemical technique, ZnO quantum dot and composites were created. The optical characteristics structural details of these examined using TEM, XRD, XPS, FT-IR, UV-vis, BET. results revealed that both the composite exhibited outstanding properties, making them suitable for photocatalytic reactions. In order to analyze performance, a degradation experiment was conducted Rhodamine B solution as simulation dye wastewater. demonstrated followed first-order reaction...

Abstract Graphite-carbon nitride (g-C 3 N 4 ) was prepared by thermocondensation, and g-C /BiVO material (GCB) /CNTs composite (GCC) were doping different contents of BiVO carbon nanotubes (CNTs) with samples, respectively. Then, , CNTs, samples doped to prepare ternary (GCBC). In the performance experiment, Sulfamethoxazole (SMZ) used as degradation evaluate photocatalytic reaction kinetics equation, quadric cycle stability free radical capture, intermediates identification studied. The SMZ...

By modifying the structure of pyridoxal phosphate, an “on–off” rhodamine fluorescent probe LPDQ with a new was synthesized. NMR, IR, and mass spectrometries characterized structures probes. The LPDQ–Zn2+ system had been successfully constructed by characteristic absorption peaks ultraviolet spectrum, experiments were carried out to investigate ion fluorescence selectivity, cell imaging, reversibility, concentration, linear range, precision, accuracy. reached detection limit 0.8 × 10−6 mol/l...

Abstract The intermediate LBXJ was prepared by Rhodamine B, hydrazine hydrate and HCl, then the probe Y2ST LBXJ, chromone 3-formaldehyde absolute ethanol. NMR characterized structures of probe, IR MS. Compared fluorescence selectivity ions after system determined tested response time, pH value, cation interference, reversibility, linearity, detection limit, accuracy, coordination ratio, recovery rate samples. limit 0.7×10 -6 mol/L, Zn 2+ in zinc gluconate 96.1% at 5×10 mol/L--5×10 -5 mol/L....

MoS2 sheets are becoming more and active in the field of anticorrosion coatings. In this work, different size were fabricated by a simple gradient centrifugation approach then introduced into epoxy coatings (EP). Composite with smaller larger also prepared for comparison. Anticorrosion properties evaluated via electrochemical spectroscopy, salt spray tests simulation calculation detail. The impedance arc doping 1.4±0.1 μm EM2000 EM2000/C1P0.2EP was 4.8×107 Ω cm2 after 7d immersing, which is...

By using an ultrasound-assisted chemical technique, ZnO quantum dot and composites were created, their optical characteristics structural details examined. Transmission electron microscopy, X-ray diffraction, photoelectron spectroscopy, Fourier transform infrared UV visible diffuse reflection used to describe. It is found that the composite have outstanding properties, which are favorable for photocatalytic reaction. Rhodamine B solution was as simulation dye wastewater in degradation...
