Determination of a broad spectrum analytes, carried out with analytical instruments in samples complex matrices, including environmental, biological, and food samples, involves the development new selective sorption phases used microextraction techniques that allow their isolation from matrix. SPME solid-phase is compatible green chemistry among sample preparation techniques, as it reduces use toxic organic solvents to minimum necessary. Over past two decades, has undergone impressive progress, resulting thin-film technique, TF-SPME (the microextraction), which characterized by much larger surface area phase compared fiber. devices, form mostly rectangular metal or polymer substrate onto thin film applied, are characterized, others, higher capacity. In comparison on fiber, they enable faster analytes. The active analyte occurs can be applied through such dip coating, spin electrospinning, rod spray coating. dynamic materials makes possible increasingly advanced technique: polymers, conducting molecularly imprinted organometallic frameworks, carbon nanomaterials, aptamers, polymeric ionic liquids, deep eutectic solvents. Therefore, been successfully prepare determine analytes matrices: food. work will review above-mentioned issues.

Development of Thin Film Microextraction with Natural Deep Eutectic Solvents as ‘Eutectosorbents’ for Preconcentration of Popular Sweeteners and Preservatives from Functional Beverages and Flavoured Waters

Molecules, Journal Year: 2024, Volume and Issue: 29(19), P. 4573 - 4573

An eco-friendly method for the determination of sweeteners (aspartame, acesulfame-K) and preservatives (benzoic acid, sorbic methylparaben, ethylparaben) in functional beverages flavoured waters using thin film microextraction (TFME) high-performance liquid chromatography with UV detection (HPLC-UV) was proposed. A series fourteen green renewable solidified natural deep eutectic solvents (NADESs) were prepared tested as ‘eutectosorbents’ TFME first time. In proposed method, NADES containing acetylcholine chloride 1-docosanol at a 1:3 molar ratio finally chosen to coat support. Four factors, i.e., mass NADES, pH samples, extraction time, desorption central composite design select optimal conditions. Limits equal 0.022 µg mL−1 aspartame, 0.020 acesulfame-K, 0.018 benzoic 0.026 0.013 0.011 ethylparaben. Satisfactory recoveries between 82% 96% achieved RSDs lower than 6.1% (intra-day) 7.4% (inter-day). The ‘eutectosorbent’ presented good stability that enabled effective extractions 16 cycles recovery least 77%. NADES-TFME/HPLC-UV is highly sensitive selective. However, use solid sorbent, synthesized without by-products, need purification, on support possibility reusability increases ecological benefit this method. greenness aspect evaluated Complex modified Green Analytical Procedure Index protocol 84/100.
