Summary: A new type of supramolecular solvent (SUPRAS) with high density, based on hexafluorobutanol (HFB) primary alcohol ethoxylate (AEO) was prepared for the first time. The SUPARS formed from MOA-3 and HFB showed better extraction efficiency compared to other SUPRASs. Parameters affecting the extraction recovery of target analytes were investigated and optimized. The proposed method is simple, fast, and green, and can be used for the analysis of target analytes in solid samples.

Summary: Developing highly efficient adsorbents for trace pollutant analysis in complex biological samples is a challenge. In this study, NiO/ZnO-coated carbon microspheres were prepared and demonstrated high adsorption capacities for malachite green (MG) and crystal violet (CV). The developed method was successfully applied for determining MG and CV in aquatic products.

Summary: With the industrialization of agriculture and the increasing use of pesticides, there is a growing need for new analysis methods to determine pesticide residues in vegetables. In this study, an efficient dispersive micro solid phase extraction method combined with dispersive liquid-liquid microextraction was used to extract eight pesticides from zucchini samples and determine them by gas chromatography. The method was validated and showed low detection limits and broad linear ranges. One of the pesticides, tebuconazole, was found and determined in a zucchini sample.
