Abstract

Trace determination of triazine herbicides in fruit and vegetables using novel hydrophobic deep eutectic solvent-based dispersive liquid-liquid microextraction followed by high-performance liquid chromatography-ultraviolet.

Porous poly(bismaleimide‐co‐divinylbenzene) microspheres as dispersive solid‐phase extraction adsorbent coupled to high‐performance liquid chromatography for the determination of triazine herbicide residues in vegetable samples

“…It is crucial to preconcentrate the analytes prior to highperformance liquid chromatography (HPLC) analysis due to the low level of THs in samples and the complexity of the sample matrix. Jouybari et al [5] established a novel hydrophobic deep eutectic solvent-based dispersive liquidliquid microextraction technique combined with HPLC for the determination of THs residues in fruit and vegetables with the enrichment factor (EF) in the range of 128-155. Pan et al [6] employed monodisperse magnetic carbon microspheres as magnetic solid-phase extraction (MSPE) adsorbent in combination with HPLC for the analysis of THs in environmental water samples with limits of detection (LODs) in the range of 0.30-0.41 ng/mL.…”

Extraction and determination of aflatoxin B1 in cereal samples using pH-switchable hydrophobic deep eutectic solvents followed by HPLC-FL analysis

“…24–26 To reduce the consumption of disperser solvent and solve this problem, researchers have used vortex and ultrasound to disperse the extractant in the aqueous phase. 27,28…”

“…[24][25][26] To reduce the consumption of disperser solvent and solve this problem, researchers have used vortex and ultrasound to disperse the extractant in the aqueous phase. 27,28 Recently, a mode of LPME based on DESs has been developed, which is called pH-switchable DESs. 29,30 In this method, aer adding DES (as an extractant) to the sample solution, the environment becomes alkaline using KOH, and DES, which is originally hydrophobic, dissolves in the sample solution and a homogeneous system is created.…”

Microextraction of Tigecycline Using Deep Eutectic Solvents and Its Determination in Milk by LC-MS/MS Method

“…The melting point of DES is lower than the same parameter for each individual component (HBA and HBD). Hydrophobic deep eutectic solvents have been acknowledged as a new class of green solvents which may replace traditional organic solvents in liquid–liquid extraction and also ionic liquids. − These extraction media exhibit unique properties, such as nonflammability, negligible vapor pressure, thermal stabilities, and low volatilities. Additionally, DES has the advantages in comparison to ionic liquids, namely, low cost, easy preparation, and production from nontoxic and biocompatible materials. , …”
