“…Pesticides (fungicide, herbicide, insecticide, acaricide, and rodenticide) have been widely applied during cultivation and post-harvest for storage of crops . Therefore, their degradation products are often found at low concentrations and in different complex matrices . Triazole fungicides (TFs) are a class of highly effective systemic fungicides containing a hydroxyl group (ketone group), a substituted phenyl group, and a 1,2,4-triazole group in the main chain .…”

A simple and sensitive preconcentration method, namely, effervescence-assisted liquid–liquid microextraction based on the ternary deep eutectic solvent method, was developed for enrichment of triazole fungicide residues prior to their determination by high-performance liquid chromatography coupled with UV detection. In this method, a ternary deep eutectic solvent (as extractant) was prepared by combination of octanoic acid, decanoic acid, and dodecanoic acid. The solution was well dispersed with sodium bicarbonate (as effervescence powder) without using auxiliary devices. In order to obtain relatively high extraction efficiency, analytical parameters were investigated and optimized. Under optimum conditions, the proposed method showed good linearity within the range of 1–1000 μg L–1 with a coefficient for determination (R 2) greater than 0.997. The low limits of detection (LODs) were in the range of 0.3–1.0 μg L–1. The precisions were assessed from the relative standard deviations (RSDs) of retention time and peak area obtained from intra- (n = 3) and inter-day (n = 5 × 5) experiments, which were greater than 1.21 and 4.79%, respectively. Moreover, the proposed method provided high enrichment factors ranging from 112 to 142 folds. A matrix-match calibration method was used for analysis of real samples. Finally, the developed method was successfully applied for determination of the triazole fungicide in environmental water (near agricultural area), honey, and bean samples, and it represents a promising alternative method for analysis of triazoles. The recoveries of the studied triazoles were obtained in the range of 82–106% with an RSD less than 4.89.

“…Since foodstuffs are very complex matrices and pesticide residues are found in a very low concentration, before instrumental analysis sample pretreatments are necessary to isolate and enrich target analytes [13]. The most commonly used sample preparation techniques to extract triazole fungicides from tomatoes and other foodstuffs are QuEChERS and dispersive‐SPE [14, 15], however other techniques such as SPE [14], SPME [17], stir bar sorptive extraction [18] magnetic SPE [19], dispersive liquid‐liquid microextraction [10], single drop microextraction, air‐assisted liquid‐liquid microextraction [20] and matrix solid‐phase dispersion (MSPD) [21] have been employed. Among these, MSPD is a widely used technique to extract organic analytes from various matrices.…”

Matrix solid-phase dispersion is an alternate technique to simultaneously extract and clean up pesticides from food matrices. In recent years, deep eutectic solvents have been applied to replace common organic solvents in various extraction techniques. One of the drawbacks of deep eutectic solvents is the impracticality of their evaporation, leading to higher limits of quantification. In this work, a deep eutectic solvent-based extraction followed by liquid-liquid back-extraction was carried out to extract five triazole fungicides from tomato samples followed by high-performance liquid chromatography-mass spectrometry analysis. For this purpose, choline chloride-ethylene glycol in a molar ratio of 1:2 and ethyl acetate was used as a deep eutectic-organic solvent system. Alumina was used as a dispersant sorbent in a 1-to-5 w/w sample-to-dispersant ratio. Volumes of 4.5 ml of deep eutectic solvents and 2 ml ethyl acetate were the best choices for backextraction. The method was fully validated. The limit of quantification was in the range of 5-11 ng/g. Intra-day and inter-day precision ranged between 3% and 14%, respectively. Extraction recoveries varied from 61% to 116%. The matrix effect was also evaluated.

“…This approach involves dispersing a little quantity of a suitable solid phase into a few milliliters of sample solution, which quickly absorbs the sample. 18,19 The adsorbed sample is then deadsorbed using a few microliters of a suitable solvent, and the result is quantified. 20,21 Adsorbents play a crucial role in DSPME, and nanomaterials are frequently utilized as adsorbents.…”
