Abstract

In the present study, a new solvent-free mode of liquid phase microextraction termed ionic liquid dispersive liquid-liquid microextraction ( IL-DLLME ) was developed. Four phenols were used as model compounds in the development and evaluation of the procedure. In this method, 50 µL of ionic liquid 1-butyl-3-methylimidazolium hexafluorophosphate ([Bmim][PF 6 ]) and 1.5 mL of sample aqueous solution were placed in a 2.2-mL glass test tube and mixed by aspirating and rapidly injecting by a syringe. This procedure produced a cloudy solution. In this process, phenols in the water sample were extracted into the IL phase. After centrifuging, the fine droplets of IL sedimented to the bottom of the glass test tube. The settled phase was injected into the high performance liquid chromatograph (HPLC) for separation and detection of phenols. Some parameters that might affect the extraction efficiency were optimized. The main advantages of the proposed method are high speed, high recovery, good repeatability and environmental friendliness.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Dispersion in DLLME can be achieved by ultrasound or by repeatedly aspiring and injecting the sample with the disperser solvent.

    “In other cases, dispersion is by ultrasound [17] or repeatedly aspiring and injecting the sample with the disperser solvent [18,19].”

    From Dispersive liquid-liquid microextraction for determination of organic analytes (2010) · cites this paper as [18]

  • IL-DLLME has a drawback of a wide peak at the beginning of the chromatogram corresponding to the IL.

    “As can be seen, at the beginning of the chromatogram, there appeared a wide peak, corresponding to the IL - one of the main drawbacks of using IL-DLLME, as already reported [14-19,32,38,47,50,65-67] -although, in this case, it did not interfere at all in the separation.”

  • Chlorinated solvents (chlorobenzene, carbon tetrachloride and chloroform) have been used as extractant solvents for endocrine disrupters, except in two works where IL [BMIm][PF6] and 1-decanol were used.

    “Chlorinated solvents have been used as extractant solvents (chlorobenzene, carbon tetrachloride and chloroform), except in two works where IL [BMIm][PF6] [18] and 1-decanol [10] were used.”

  • Endocrine disrupters, antioxidants, PAHs and other organic compounds of different natures have been analyzed by DLLME, IL-DLLME and DLLME-SFO.

    “Endocrine disrupters [10,18,57,59,80-83], antioxidants [62,84], PAHs [9,11,66,67,85,86] and other organic compounds of different natures [7,8,63, 87-104] have been analyzed by DLLME, IL-DLLME and DLLME-SFO.”

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.
