A high-throughput semi-automated dispersive liquid–liquid microextraction based on deep eutectic solvent for the determination of neonicotinoid pesticides in edible oils
In this study, a high-throughput automated pipetting system was innovatively combined with dispersive liquid–liquid microextraction (DLLME). This application automates the sample and solvent addition steps in DLLME and allows simultaneous batch sample processing, thereby, greatly saving labor and time. The use of a deep eutectic solvent (DES) instead of traditional organic solvents as the extractant makes the whole extraction process environmental-friendly. Under optimized conditions, the method exhibits satisfactory extraction performance for all target analytes. The limits of detection for thiamethoxam, imidacloprid, and thiacloprid in the rapeseed oil matrix are 5.8, 2.9, and 2.7 μg L−1, respectively. It is worth mentioning that this high-throughput automatic pipetting system can be applied to different types of DLLME. Furthermore, the greenness of the established method is evaluated using the AGREE metric and the results show distinct advantages, such as fast operation, automation, and environmental friendliness, compared to previously published works for the detection of neonicotinoids in edible oils.
期刊介绍：
The Microchemical Journal is a peer reviewed journal devoted to all aspects and phases of analytical chemistry and chemical analysis. The Microchemical Journal publishes articles which are at the forefront of modern analytical chemistry and cover innovations in the techniques to the finest possible limits. This includes fundamental aspects, instrumentation, new developments, innovative and novel methods and applications including environmental and clinical field.
Traditional classical analytical methods such as spectrophotometry and titrimetry as well as established instrumentation methods such as flame and graphite furnace atomic absorption spectrometry, gas chromatography, and modified glassy or carbon electrode electrochemical methods will be considered, provided they show significant improvements and novelty compared to the established methods.
