Article Abstract
In recent years, green solvents have emerged as promising alternatives in the field of analytical chemistry, replacing conventional organic solvents known for their toxicity, volatility, and flammability. The combination of these solvents with liquid-liquid microextraction techniques has facilitated the development of simpler, faster, more economical, and environment-friendly methodologies for the analysis of samples of varying complexity. This review discusses the fundamental physicochemical properties and advantages of using deep eutectic solvents, ionic liquids, switchable-hydrophilicity solvents, supramolecular solvents, and surfactants as extractants. Furthermore, analytical methods based on liquid-liquid microextraction techniques developed in the last 5 years for the determination of organic compounds and metals in biological and environmental samples are presented and discussed, highlighting their applications and benefits to improve analytical performance and sustainability.

In this study, tetrabutylammonium chloride (TBAC), tetrabutylammonium bromide (TBAB), and choline chloride (ChCl) were innovatively applied in the liquid-liquid microextraction (LLME) of bisphenol A (BPA) from edible oil by forming water-based deep eutectic solvent (WDES). The presence of water is not only used in the synthesis of WDES, but also modulates the viscosity of DES and improve its diffusion and mass transfer properties. Several crucial parameters affecting the extraction efficiency were examined, including the type and amount of WDES and the extraction time.

The release of microcystin (MCs) in aquatic ecosystems poses a substantial risk to the safety of irrigation and drinking water. In view of the challenges associated with monitoring MCs in water bodies, given their low concentration levels (μg/L to ng/L) and the presence of diverse matrix interferences, there is an urgent need to develop an efficient, cost-effective and selective enrichment technique for MCs prior to its quantification. In this work, a gold nanoparticles (AuNPs)-functionalized zwitterionic polymer monolith was described and further applied for the affinity enrichment of MCs.

Monitoring paracetamol levels in environmental samples is essential, as this widely used pharmaceutical can degrade water quality and adversely affect both ecosystems and human health. To address this issue, a novel, simple, sensitive, and accurate method has been developed. This method employs a functionalized ionic liquid, 2-(4-hydroxybenzyl)hydrazinium chloride ([HBH][Cl]), specifically designed to structurally mimic paracetamol and function as a complexing agent.

A reliable and sensitive analytical platform is proposed for the assessment of pig exposure to mycotoxins through the consumption of commercial feed. A total of 48 naturally contaminated feed and 55 urine samples collected from eight Spanish farms were analyzed using a fast and simple methodology based on solid-liquid extraction (SLE) or liquid-liquid extraction (LLE) and dispersive liquid-liquid microextraction (DLLME). High-performance liquid chromatography coupled to tandem mass spectrometry (HPLC-MS/MS) was used for the targeted analysis of 27 mycotoxins from different families in both matrices achieving limits of quantification in a range of 0.
