“…14,24 Various sample preparation techniques have been developed in previous work for the extraction and concentration of methadone and codeine in distinct real samples. These methods include solid-phase extraction (SPE), 1 dispersive solid-phase microextraction (DSPME), 25 dispersive liquid-liquid microextraction (DLLME), 11,19 air-assisted emulsification liquid-liquid microextraction (DES-AAELLME), 12 ultrasound-assisted dispersive liquidliquid microextraction (UA-DLLME), 26 homogenous liquid-liquid microextraction (HLLME), 27 hollow fiber liquid-phase microextraction (HF-LPME), 28 solvent bar microextraction (SBME) 29 and electromembrane extraction (EME). 30 The mention methodologies have been utilized for the determination of MDN and COD in various biological matrices, such as urine, 11,12,18,[28][29][30] plasma or blood, 11,12,19,[28][29][30] saliva 11 and sweat.…”

“…9,10 To achieve optimum treatment, new analytical methods and time-saving sample preparation techniques for the determination of methadone in blood extract samples have been used. 11,12 The opiate alkaloid codeine (3-methyl morphine; COD) is extracted from poppy flowers and is produced from morphine by a methylation reaction, 13 which is extensively used as a cough and pain reliever. 14 COD is an inactive drug yet, by the liver enzyme (CYP2D6) can be demethylated to active morphine, which is considered fatal for its excessive intake and can be addictive for long-term use.…”

A continuous sample drop flow microextraction (CSDF-ME) technique was modified for the pretreatment of plasma samples in the determination of methadone and codeine. The limit of detection and linear range for methadone were 15.0 µg L −1 and 0.1-10.0 mg L −1 , respectively. The detection limit and linear range for codeine were 25.0 µg L −1 and 0.2-15.0 mg L −1 , respectively. The extraction recoveries were 41.6-52.1%, and the enrichment factors ranged from 65 to 80 for codeine and methadone, respectively. Intra-and interday precisions of the technique were calculated for codeine and methadone concentrations of 0.4 mg L −1 and were 4.2-7.6% and 2.5-5.1%, respectively. Also, the accuracy (error%) of method was in the range −10 to +7.5%. The applicability of the CSDF-ME-gas chromatography-flame ionization detector (GC-FID) technique was illustrated by the determination of the mentioned drugs in human plasma. The attained relative recoveries of methadone and codeine in the 90.0-107.5% range demonstrated the excellent capability of the optimized technique for the microextraction of the mentioned drugs from plasma. The CSDF-ME-GC-FID is a rapid, repeatable and very simple technique that requires a low sample amount.

In this work, a method for the analysis of benzoylurea insecticides, including hexaflumuron, flufenoxuron, lufenuron and chlorfluazuron, in tea samples by highperformance liquid chromatography with Fe 3 O 4 -hyperbranched polyester nanocomposite as the adsorbent for magnetic solid-phase extraction was developed. The magnetic nanocomposite was prepared and characterized by infrared spectroscopy, vibrating sample magnetometry, and scanning electron microscopy. The as-prepared nanocomposite was used as a sorbent for the extraction and preconcentration of pesticide residues in tea samples. The extraction and desorption conditions, including mass ratios of raw materials, amount of sorbent, pH value, extraction time, and desorption time, were investigated. Under the final conditions chosen for the analysis, good linearity was obtained for all the tested compounds, with R 2 values of at least 0.9979. The limits of detection were determined in the range of 0.15-0.3 μg/L. The recovery obtained from the analysis of tea samples with various spiked concentrations was between 90.7 and 98.4%, with relative standard deviations (n = 4) lower than 4.1%. Furthermore, the present approach was successfully applied to the quantitative determination of residues of benzoylurea insecticides in real samples.

“…However, a majority of the DESs are not stable in water, and cannot be applied in aqueous environment samples. So far, only a few hydrophobic DESs have been reported for the extraction of analytes from aqueous samples [10][11][12][13][14][15][16]. Considering the diversity of analytes, it was very necessary to develop further hydrophobic DESs.…”

In recent years, hydrophobic deep eutectic solvents as new generation of green solvents have attracted wide attention in liquid microextraction technique. In this article, four hydrophobic deep eutectic solvents composed of trioctylmethylammonium chloride and oleic acid were designed and prepared firstly. Combined with high‐performance liquid chromatography, these deep eutectic solvents were used as an extraction solvent in vortex‐assisted dispersive liquid–liquid microextraction for the selective enrichment and indirect determination of trace nitrite from real water and biological samples. This method is based on the diazotization‐coupling reaction of nitrite with p‐nitroaniline and diphenylamine in acidic water, and then the nitrite is quantified indirectly by measuring the obtained azo compounds. Some factors influencing the extraction efficiency, including the reaction and extraction conditions, were investigated. Under the optimized conditions, the method has a linear range of 1–300 μg/L with a correlation coefficient of 0.9924, limit of detection of 0.2 μg/L, limit of quantitation of 1 μg/L, intraday and interday relative standard deviations of 4.0 and 6.0%. This method was successfully applied in determination of nitrite from three environmental water and two biological samples with the recovery in the range of 90.5–115.2%. In addition, these results were well agreement with those obtained by the conventional Griess method.
