“…Therefore, several devices including shakers, vortex mixers, and ultrasonic probes and baths have been implemented for sorbent dispersion. Until today, the ultrasound-assisted dispersive solid-phase microextraction is the most common d-SPE approach [24,69].…”

Metal–organic frameworks (MOFs) are crystalline porous materials composed of metal ions or clusters coordinated with organic linkers. Due to their extraordinary properties such as high porosity with homogeneous and tunable in size pores/cages, as well as high thermal and chemical stability, MOFs have gained attention in diverse analytical applications. MOFs have been coupled with a wide variety of extraction techniques including solid-phase extraction (SPE), dispersive solid-phase extraction (d-SPE), and magnetic solid-phase extraction (MSPE) for the extraction and preconcentration of metal ions from complex matrices. The low concentration levels of metal ions in real samples including food samples, environmental samples, and biological samples, as well as the increased number of potentially interfering ions, make the determination of trace levels of metal ions still challenging. A wide variety of MOF materials have been employed for the extraction of metals from sample matrices prior to their determination with spectrometric techniques.

“…Thus, sample preparation methods are frequently developed prior to instrumental measurements to isolate and preconcentrate the analyte(s) from complex matrices. There are several methods for the extraction and preconcentration of compounds such as dispersive liquid-liquid microextraction (DLLME) [ 19 ], switchable-hydrophilicity solvent liquid-liquid microextraction (SHS-LLME) [ 20 ], hollow fiber liquid phase microextraction (HF-LPME) [ 21 ], solidified floating organic drop microextraction (SFODME) [ 22 ], dispersive solid phase microextraction (DSPME) [ 23 ], solid phase microextraction (SPME) [ 24 ], single drop microextraction (SDME) [ 25 ], and spraying-based fine droplet formation–liquid phase microextraction (SFDF-LPME) [ 26 ] to increase the detection power of the instrument. In the SFDF-LPME method, the extraction solvent is dispersed into the standard/sample solution with the help of air pressure, without the dispersive solvent; therefore, organic solvent consumption is lowered [ 26 ].…”

“…The dispersion methods used, aside from the use of the dispersive agent, can be different in the analytical DLLME technique. For instance, one dispersion technique is temperature-controlled dispersive liquid-phase microextraction (TC-DLPME) [12], which can only be applied when the solubility of the extraction solvent is a function of temperature: a change in temperature greatly changes the solubility of the solvent, which mixes completely with the aqueous solution of the sample [13,14]. Another dispersion technique is ultrasound dispersive liquid-liquid micro extraction (US-DLLME), which uses ultrasound energy to develop the emulsion process of the extraction solvent in the sample solution without any dispersive solvent [15,16].…”

In this paper, an analytical protocol was developed for the simultaneous determination of phthalates (di-methyl phthalate DMP, di-ethyl phthalate DEP, di-isobutyl phthalate DiBP, di-n-butyl phthalate DBP, bis-(2-ethylhexyl) phthalate DEHP, di-n-octyl phthalate DNOP) and bisphenol A (BPA). The extraction technique used was the ultrasound vortex assisted dispersive liquid–liquid microextraction (UVA-DLLME). The method involves analyte extraction using 75 µL of benzene and subsequent analysis by gas chromatography combined with ion trap mass spectrometry (GC-IT/MS). The method is sensitive, reliable, and reproducible with a limit of detection (LOD) below 13 ng g−1 and limit of quantification (LOQ) below 22 ng g−1 and the intra- and inter-day errors below 7.2 and 9.3, respectively. The method developed and validated was applied to six honey samples (i.e., four single-use commercial ones and two home-made ones. Some phthalates were found in the samples at concentrations below the specific migration limits (SMLs). Furthermore, the commercial samples were subjected to two different thermal stresses (24 h and 48 h at 40 °C) for evidence of the release of plastic from the containers. An increase in the phthalate concentrations was observed, especially during the first phase of the shock, but the levels were still within the limits of the regulations.
