Amaranth is widely added to food and can cause many adverse health effects when it excessively consumed. Therefore, the monitoring of amaranth quite important. Herein, an electrochemical sensor for sensitive rapid detection was reported using multiwall carbon nanotube (MWNT) as sensing film. Due large surface area high accumulation efficiency, MWNT showed a strong enhancement effect on oxidation amaranth, greatly increased current signal. The conditions such pH value, amount MWNT, potential...
Short-chain fatty acids (SCFAs), produced by anaerobic fermentation of mainly indigestible dietary carbohydrates gut microbiota, have a profound influence on intestinal function and host energy metabolism. Antibiotics may seriously disturb the balance fecal SCFAs. To evaluate impacts antibiotics SCFAs simple, reproducible accurate gas chromatography (GC) method, which can simultaneously analyze seven in samples, was developed validated. The ranges detection quantitation reached 0.0868 ~...
Carbon nanotubes@zeolitic imidazole framework-67 (CNTs@ZIF-67), a conductive composite was prepared from carboxylic carbon nanotubes and cobalt-imidazole framework. It possesses an excellent adsorption capacity (92.12 mg g-1) for the flame retardant tetrabromobisphenol A (TBBPA). The characterized by transmission scanning electron microscopy, FTIR X-ray diffractometry. then used to modify acetylene black electrode. Electrochemical studies showed current response of modified electrode be...
The main adsorption mechanism for phosphate removal from MgAl-LDH@ZIF-8 composites includes electrostatic attraction, ion exchange, and ligand exchange.
Abstract The widespread abuse of anabolic androgenic steroids by healthy people leads to the risk major mood disorders and heart failure; thus, determination is vital. In this study, 17 in dietary supplements external drugs were identified, their concentration was determined. For purpose, polyaniline‐coated magnetic nanoparticles prepared then subjected solid‐phase extraction combined with high‐performance liquid chromatography–tandem mass spectrometry. experimental parameters studied...
Oxidative stress plays a crucial role in numerous cardiovascular diseases. As an effective therapy, Danhong injection (DHI) is considered to act through antioxidant mechanism for the treatment of disease. In our study, we focused on potential contribution capacity DHI fractions (Frs) and established innovative screening method based 2,2-diphenyl-1-picrylhydrazyl radical scavenging activity assay. A ternary network evaluation system, which was constructed activity, area under...
A method combining QuEChERS with liquid chromatography-tandem mass spectrometry (LC-MS/MS) was developed for the determination of higenamine in Chinese herbal medicine, condiments, and topical medicine. The sample subjected to extraction using a formic acid-ethanol mixture, followed by purification sorbents; then, solution introduced into LC-MS/MS system detection multiple reaction monitoring (MRM) mode. Under optimal conditions, limit 0.03 ng/g, linear range 0.10-100 ng/g relative standard...
β -Cyclodextrins/acrylic acid modified magnetic gelatin was prepared and then employed as the solid-phase extraction (MSPE) sorbent for of moxidectin in milk samples. Due to rigidity hydrophobic cavity -cyclodextrins carboxyl groups acrylic acid, composites are form a complex with target molecules through various kinds chemical reactions showed excellent performance. This method exhibits advantages simplicity implementation, short time (5 min), low solvent consumption, high efficiency. A...
A novel approach was developed to prepare molecularly imprinted polymer (MIP) composites on filter paper and with the subsequent determination of sulfamethoxazole in food samples. Hemoglobin firstly encapsulated a metal-organic framework improve its stability catalytic performance. This mixture modified an initiator immobilized MIP using electrochemically mediated atom transfer radical polymerization. composite exhibited excellent adsorption capacity (60.1 mg g−1) rapid kinetics, which were...
A novel core–shell Fe 3 O 4 @ZIF-8-PSS adsorbent was synthesized by a one-step method. The maximum adsorption capacity for cationic dye crystal violet (CV) can reach 382 mg g −1 , and the be magnetically separated recovered within 10 s.
