“…The advantages of the recent approaches based on adsorptive extraction are that they require little or no organic solvents, consume little plant samples, have higher extraction efficiency, and are simple to use. The effective strategy to increase the sensitivity of the adsorptive extraction methods relies on the use of nanoporous materials in which the interactions between the target compounds and the sorbent are increased (Jiang, Huang, Feng, & Wang, 2016). Porous materials are particularly attractive because of their high porosity and specific surface area (Song et al, 2016).…”

A headspace (HS) solid‐phase extraction (SPE) based on polydimethylsiloxane (PDMS)/ionic liquid (IL) sponge was developed for the extraction of lavender essential oil. The PDMS after loading of 1‐butyl‐3‐methylimidazolium tetrachloroferrate ([BMIM]FeCl4) with a high surface area and excellent adsorption capacity was successfully applied in the SPE process. Microwave distillation (MD) coupled with HS‐PDMS/[BMIM]FeCl4 extraction after GC–MS was proposed. Various experimental parameters were studied. The optimal conditions were as follows: optimal IL, [BMIM]FeCl4; volume ratio of IL to ethanol, 1:5; extraction solvent, n‐hexane; microwave power, 600 W; and irradiation time, 12 min. The limits of detection and quantification of the analytic compounds were in the ranges 4.00–16.32 and 10.00–40.00 ng, respectively. The intra‐day and inter‐day precisions were in the ranges 0.37–1.94% and 1.20–2.45%, respectively. Under the optimized conditions, 13 samples of 3 lavender varieties were analyzed, and 40 compounds were identified. Lavender varieties were distinguished using principal component analysis. The results showed that MD‐HS‐PDMS/IL‐GC–MS is a novel, simple, and sensitive method for the determination of essential oil in complex plant samples.

“…Excessive use of OPPs leads to their residues being found in ground water, fruits, vegetables, and drinking water. It has been reported that intoxication of OPPs is one of the major toxic incidents related to OPP residues in cereals, vegetables, and fruits . The maximum residue limits established by the European Union for OPPs in fruits and vegetables is 0.01‐0.3 mg/kg .…”

In the present work, a high‐efficiency and solvent minimized microextraction technique, fabric phase sorptive extraction followed by gas chromatography and mass spectrometry analysis is proposed for the rapid determination of four organophosphorus pesticides (terbufos, malathion, chlorpyrifos, and triazofos) in vegetable samples including beans, tomato, brinjal, and cabbage. Fabric phase sorptive extraction combines the beneficial features of sol‐gel derived microextraction sorbents with the rich surface chemistry of cellulose fabric substrate, which collectively form a highly efficient microextraction system. Fabric phase sorptive extraction membrane, when immersed directly into the sample matrix, may extract target analytes even when high percentage of matrix interferents are present. The technique also greatly simplifies sample preparation workflow. Most important fabric phase sorptive extraction parameters were investigated and optimized. The developed method displayed good linearity over the concentration range 0.5–500 ng/g. Under optimum experimental conditions, the limits of detection were found in the range of 0.033 to 0.136 ng/g. The relative standard deviations for the extraction of organophosphorus pesticides were < 5%. Subsequently, the new method was applied to beans, tomato, brinjal, and cabbage samples. The results from the real sample analysis indicate that the method is green, rapid, and economically feasible for the determination of organophosphorus pesticides in vegetable samples.

“…Thus, it is important to develop a rapid, simple, sensitive, environmentally friendly, and easily operated analytical method for the determination of OPPs residues in food, environmental, and biological matrixes. Various analytical methods including GC and HPLC have been used for the determination of OPPs residues. However, owing to the matrix interferences and low concentration of pesticides in real samples, an appropriate separation and preconcentration step is required before instrumental analysis.…”

A simple, environmentally benign, and rapid method based on temperature-controlled liquid-liquid microextraction using a deep eutectic solvent was developed for the simultaneous extraction/preconcentration of diazinon and fenitrothion. The method involved the addition of deep eutectic solvent to the aqueous sample followed by heating the mixture in a 75°C water bath until the solvent was completely dissolved in the aqueous phase. Then, the resultant solution was cooled in an ice bath and a cloudy solution was formed. Afterward, the mixture was centrifuged and the enriched deep eutectic solvent phase was analyzed by high-performance liquid chromatography with ultraviolet detection for quantification of the analytes. The factors affecting the extraction efficiency were optimized. Under the optimized extraction conditions, the limits of detection for diazinon and fenitrothion were 0.3 and 0.15 μg/L, respectively. The calibration curves for diazinon and fenitrothion exhibited linearity in the concentration range of 1-100 and 0.5-100 μg/L, respectively. The relative standard deviations for five replicate measurements at 10.0 μg/L level of analytes were less than 2.8 and 4.5% for intra- and interday assays, respectively. The developed method was successfully applied to the determination of diazinon and fenitrothion in water and fruit juice samples.
