| description | An in situ formation of ionic liquid was used for preconcentration of four triazole fungicides in food samples. The microextraction method was used for the first time in the literature for preconcentration of triazole fungicides. In the developed method, tributylhexadecylphosphonium bromide ([P<sub>44412</sub>]Br) and potassium hexafluorophosphate (KPF<sub>6</sub>) were used for the formation of hydrophobic ionic liquid. After centrifugation, the fine microdroplets were produced in one step, providing the extraction step in a quick and environmentally friendly manner. The functional group of the hydrophobic ionic liquid was investigated using FT-IR. Various extraction parameters were studied and optimized. In the extraction method, 0.01 g of [P<sub>44412</sub>]Br and 0.01 g of KPF<sub>6</sub>, centrifugation at 4500 rpm for 10 min were used. The optimized technique provided a good linear range (90–1000 μg L<sup>−1</sup>) and high extraction recovery, with a low limit of detection (30–50 μg L<sup>−1</sup>). Methods for the proposed in situ formation of ionic liquid were successfully applied to honey, fruit juice, and egg matrices. The recoveries were obtained in a satisfactory range of 62–112%. The results confirmed the suitability of the proposed microextraction method for selective extraction and quantification of triazole fungicides. |
