Abstract

BACKGROUND: In this research, a new extraction method based on dispersive liquid–liquid microextraction and the solidification of deep eutectic solvent has been developed for the determination of heavy metals in soil and vegetables prior to their analysis by graphite furnace atomic absorption spectrometry (GFAAS). In this method, a green solvent consisting of 1‐decyl‐3‐methylimidazolium chloride and 1‐undecanol was used as an extraction solvent, yielding the advantages of material stability, low density and a suitable freezing point near room temperature. RESULTS: Under optimal conditions, enrichment factors are in the range of 114–172. The calibration graphs are linear in the range of 0.02–200 µg kg−1 and limits of detection are in the range of 0.01–0.03 µg kg−1. Repeatability and reproducibility of the method based on seven replicate measurements of 0.80 µg kg−1 of Hg and 0.20 µg kg−1 of Pb and Cd in analyzed samples were in the range of 2.3–4.1% and 3.7–6.6%, respectively. CONCLUSION: A new deep eutectic solvent consists of two parts: 1‐decyl‐3‐methylimidazolium chloride and 1‐undecanol in a molar ratio of 1:2. The accuracy of the proposed procedure was also assessed by determining the concentration of the studied metal ions in a polluted farmland soil standard reference material. © 2018 Society of Chemical Industry

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.
