Hydrophobic Deep Eutectic Solvents Based Membrane Emulsification-Assisted Liquid-Phase Microextraction Method for Determination of Pyrethroids in Tea Beverages
Abstract
Deep eutectic solvents (DESs) were used as an extractant for the determination of pyrethroids in environmental water and tea beverage samples. Three different acids were chosen as hydrogen bond donors for preparation of DESs, and decanoic acid was optimal because of its high recovery. Factors affecting relative recovery were optimized individually, including salt addition, surfactant addition, extraction temperature, DES amount, and sample volume etc. Under the optimized experimental conditions, the relative recovery of pyrethroids was from 89.3% to 97.7%, with relative standard deviation (RSD) values ranging from 1.75% to 2.73%. The linear correlation coefficient ranged from 0.9981 to 0.9992, and the linear range was between 1.9 and 500 μg/L. Based on a signal-to-noise ratio (S/N) of 3:1, the limit of detection (LOD) values were 0.56 to 1.24 μg/L. The enrichment factor ranged from 92 to 105. In conclusion, good extraction efficiency was achieved in tea beverage samples under the optimized conditions.

Membrane-based and chromatomembrane extraction techniques generate cleaner extracts and exhibit better compatibility with continuous-flow and automated analytical platforms, as analyte transfer takes place through a precisely controlled membrane interface.
“Similarly, membrane-based and chromatomembrane extraction techniques generate cleaner extracts and exhibit better compatibility with continuous-flow and automated analytical platforms, as analyte transfer takes place through a precisely controlled membrane interface [51,73,96].”

SPE, MSPE, membrane-assisted extraction, and DES-modified sorbents are primarily designed to enhance selectivity and improve matrix purification.
“Unlike liquid-phase microextraction techniques, solid-phase extraction (SPE), magnetic solid-phase extraction (MSPE), membrane-assisted extraction, and DES-modified sorbents are primarily designed to enhance selectivity and improve matrix purification [51,72,73,76,96].”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
