Application of deep eutectic solvents in analytical sample pretreatment (update 2017-2022). Part A: Liquid phase microextraction

Vasil Andruch et al.

Summary: Sustainable development has become a necessity in all areas of human activity, and green chemistry is closely related to it. In the field of analytical chemistry, various approaches have been proposed to meet the requirements of green chemistry, such as the research of new reagents and solvents for analytical purposes. Deep eutectic solvents (DESs) have been investigated and used in analytical chemistry since the mid-2000s, leading to a significant increase in published works in this area. This paper focuses specifically on the applications of DESs in liquid-liquid (micro)extraction (LLME) procedures for the determination of organic and inorganic analytes in different matrices. The use of DESs in sorbent-based procedures will be discussed in a separate paper.

Development of magnetic dispersive micro-solid phase extraction of four phenolic compounds from food samples based on magnetic chitosan nanoparticles and a deep eutectic supramolecular solvent

Xiaoping Hai et al.

Summary: We developed a magnetic dispersive micro-solid phase extraction technique using magnetic chitosan nanoparticles and a deep eutectic supramolecular solvent for the determination of four phenolic compounds in food samples. Deep eutectic supramolecular solvents were used as novel green eluents due to their higher desorption capacities compared to conventional organic solvents. The optimized method showed excellent analytical performance with a linear range of 0.1-200.0 μg·mL-1, high extraction recoveries (>94.8%), and low precision (RSD% < 2.9%).
