“…This method involves an organic extraction solvent, a dispersive solvent (which must have the ability to disperse in both the aqueous and organic phases) and the aqueous solution of the sample [11]. So far, many applications of this method have been reported in various fields [12][13][14].…”

In the present work, the use of microextraction methods for the separation and pre-concentration of narcotic drugs in urine and vitreous samples is presented. These simple and eco-friendly methods are used to measure tramadol and methadone, which are used to relieve pain and treat addiction to other drugs. Urine and vitreous samples from 54 corpses referenced to legal medicine were analyzed by high performance liquid chromatography. Extraction of tramadol and methadone was performed separately using 200 μl chloroform, 700 μl methanol at pH 10. Under the optimum conditions, the detection limit linear range were obtained 4.5 µg L-1 and 1.2 µg L-1 , 4.5-1000 µg L −1 and 1-1000 µg L −1 for determination of tramadol and methadone, respectively. According to the results, for accurate interpretation of the methadone and tramadol concentration in the bodies, its measurement in vitreous fluid is very useful and practical.

“…Among the different variants of the DLLME technique developed recently [41][42][43][44][45], the authors optimized the ultrasound-vortex-assisted dispersion liquid-liquid microextraction (UVA-DLLME). In fact, already in other studies carried out by this research group [46][47][48][49], the authors have focused their attention on the elimination of the dispersive solvent in favor of reducing the solvents used.…”

Over the years, anthropogenic sources have increasingly affected food quality. One of the most sensitive and nutritional matrices affected by chemical contamination is honey, due to the use of acaricides. Recently, the attention has moved to the presence of phthalates (PAEs) and bisphenol A (BP-A), molecules present in plastic materials used both in the production phase and in the conservation of honey. In this study, an analytical method for the simultaneous determination of PAEs (dimethyl phthalate DMP, diethyl phthalate DEP, diisobutyl phthalate DiBP, dibutyl phthalate DBP, bis(2-ethylhexyl) phthalate DEHP, and di-n-octyl-phthalate DnOP) and BP-A was developed. The extraction technique is the ultrasound-vortex-assisted dispersive liquid–liquid microextraction (UVA-DLLME), using 150 µL of toluene as an extraction solvent, followed by the gas chromatography coupled with ion trap mass spectrometry analysis (GC–IT/MS). The developed method is sensitive, reliable, and reproducible: it shows high correlation coefficients (R > 0.999); limits of detection (LODs) less than 11 ng·g−1; limits of quantification (LOQs) less than 16 ng·g−1; repeatability below 3.6%, except BP-A (11.6%); and accuracy below 4.8%, except BP-A (17.6%). The method was applied to 47 nectar honey samples for evidencing similarities among them. The chemometric approach based on Hierarchical Cluster Analysis and Principal Component Analysis evidenced some similitudes about sample origin as well as marked differences between PAE and BP-A sources.

“…The clean-up procedure and quality monitoring are usually required prior determination of PAH contaminants in water. There are many scientific articles that reveal the possibility of dispersive liquid-liquid micro extraction method 8,9 and solid-phase extraction of PAHs followed by its pre-concentration from water 10 , precipitates 11 and aerosol 12 . The acceptable limit of PAHs in the environment, especially water bodies, is less than 5 mg L −1 .…”
