Journal of Separation Science, Accepted Article. Nitro-polycyclic aromatic hydrocarbons have been detected in various environmental media. However, determination in sediment matrix is challenging due to the lack of a suitable method. In this study, a reliable method for determining 15 nitro-polycyclic aromatic hydrocarbons in sediments was developed based on accelerated solvent extraction and solid-phase microextraction coupled with GC-MS/MS.

Journal of Separation Science, Accepted Article. A new green miniaturized quick, easy, cheap, effective, rugged, and safe approach was developed and used for the extraction of multiclass 16 pesticides in milk before GC analysis. The miniaturization of method reduced the consumption of chemical reagents and samples. Magnetic three-dimensional graphene was used as sorbent in the clean-up step. Choline chloride:lactic acid (1:2) natural deep eutectic solvent was used as desorption solvent.

Journal of Separation Science, Accepted Article. Hydroxyl polycyclic aromatic hydrocarbons are considered active mutagenic and carcinogenic substances and are found in extremely low levels (ng/g) in biological samples. As a result, their determination in urine and blood samples is challenging, and a sensitive and effective method for the analysis of trace hydroxyl polycyclic aromatic hydrocarbons in complex biological matrices is required.

Journal of Separation Science, Accepted Article. In this study, a 4-formylphenylboronic acid modified cross-linked chitosan magnetic nanoparticle (FPBA@CCHS@Fe3O4) was fabricated. The synthesized material was utilized as the magnetic solid phase extraction adsorbent for the enrichment of six benzoylurea pesticides.

Journal of Separation Science, Accepted Article. By monomer-mediated in-situ growth synthesis strategy, with hydroquinone and 1,3,5-tris(4-aminophenyl)benzene as monomers, a core-shell magnetic porous organic polymer was synthesized through simple azo reaction. Based on this, a magnetic solid-phase extraction-HPLC-fluorescence detection method was proposed for the analysis of fluoroquinolones in honey sample.

Journal of Separation Science, Accepted Article. In the present study, we propose a novel method for the extraction of parabens in personal care products. A new, simple adsorptive material was obtained by combining metal-organic frameworks and melamine sponges using the adhesive property of polyvinylidene fluoride. This new material, metal-organic frameworks /melamine sponges, was found to be particularly suitable for solid phase extraction.

Journal of Separation Science, Accepted Article. High-performance liquid chromatography tandem mass spectrometry (HPLC-MS/MS) coupled with the quick, easy, cheap, effective, rugged and safe method was established for the qualitative and quantitative detection of twenty mycotoxins in milk. The linear range of this method was 0.01-10μg/L, and the correlation coefficients were all greater than or equal to 0.9933.

Journal of Separation Science, Accepted Article. In this work, magnetic mesoporous polymelamine-formaldehyde composites were synthesized via a facile Schiff base reaction. The magnetic mesoporous polymelamine-formaldehyde composites combined both the properties of mesoporous polymelamine-formaldehyde and the magnetism of NH2-SiO2@Fe3O4 nanoparticles, possessing high specific surface area (150.66 m2 g–1) and good magnetism (24.50 emu g–1).

Journal of Separation Science, Accepted Article. Mesoporous silica santa barbara-15 was functionalized by methacryloxypropyl trimethoxysilane. Taking this as the carrier material, a new mesoporous silica surface imprinted polymer was synthesized by using the C = C bond, functional monomer α-methacrylic acid and crosslinker ethylene glycol dimethacrylate, which was used to extract aflatoxin from grain efficiently.

Journal of Separation Science, Accepted Article. Zearalenone is a fungal contaminant that is widely present in grains. Here, a novel molecularly imprinted membrane based on SOM-ZIF-8 was developed for the rapid and highly selective identification of zearalenone in grain samples. The molecularly imprinted membrane was prepared using polyvinylidene fluoride, cyclododecyl 2,4-dihydroxybenzoate as a template and SOM-ZIF-8 as a carrier.

Journal of Separation Science, Accepted Article. In this study, a new Ti3C2Tx-coated fiber was synthesized and utilized as coatings for solid-phase microextraction of seven polychlorinated biphenyls. The as-produced multilayered Ti3C2Tx MXene was characterized by X-ray diffractometer, thermos-gravimetric analysis, scanning electron microscopy, and energy dispersive spectroscopy.

Journal of Separation Science, Accepted Article. In this paper, a method for the separation of triadimenol stereoisomers using ultra-performance convergence chromatography and an analytical method for the determination of triadimenol stereoisomer residues in pumpkin puree, apple puree, and tomato puree as a supplement for infants are established. Test samples were extracted with acetonitrile and successively purified with graphitized carbon black and Florisil column.

Journal of Separation Science, Accepted Article. Endocrine disrupting chemicals are chemicals that interfere with any aspect of the endocrine system. Several natural and synthetic chemicals including pesticides have been identified as endocrine disruptors, which potentially inhibit the reproductive activity of the hormonal system. The pervasive occurrence with trace level concentrations and extensive variety are the reported characteristics of these chemicals.

Journal of Separation Science, Accepted Article. Bubble-bursting flow microextraction combined with gas chromatography as a green and sustainable microextraction method is used to determine some organophosphorus pesticide residues in water samples. The extraction process occurs at the surface of liquid-gas contact, where the analytes interact with the gas molecules in the bubble. The analytes are transferred to the surface of the sample solution by moving the gas bubbles upwards.

Journal of Separation Science, Accepted Article. Pesticides and veterinary drugs are generally employed to control pests and insects in crop and livestock farming. However, remaining residues are considered potentially hazardous to human health and the environment. Therefore, regular monitoring is required for assessing and legislation of pesticides and veterinary drugs. Various approaches to determining residues in various agricultural and animal food products have been reported.

Journal of Separation Science, Accepted Article. In this study, a new floating dispersive solid phase extraction method based on deep eutectic solvents has been developed in a home–made extraction device for the extraction of four tetracycline antibiotics from milk samples. In this approach, the sorbent (activated carbon) was dispersed in whole parts of solution with the aid of air stream and floated on top of the solution with the aid of the surfactant (lauryl betaine) and air bubbles.

Journal of Separation Science, Accepted Article.The intensive application of pesticides to increase crop production has resulted in contamination of the agricultural products. Due to their occurrence at trace levels and the complexity of food samples, analysis of pesticide residues requires selective and efficient sample preparation methods.
