“…To overcome the difficulty associated with extraction solvent, magnetic ionic liquids (MILs) were introduced and used in the extraction procedure [15]. By application of this type of solvents, the need for centrifugation process is omitted and the solvent droplets can be isolated from the sample solution in the presence of an external magnetic field [16,17]. Also, DLLME cannot be directly applied on solid samples or complex matrices.…”

In the present work, a combination of microwave-assisted extraction with magnetic ionic liquid-based dispersive liquid-liquid microextraction was developed for the extraction of chloramine-T from fish samples. In this method, the sample was mixed with a hydrochloric acid solution and exposed to microwave irradiations. By doing so, chloramine-T was converted to p-toluenesulfonamide and extracted from the sample into an aqueous phase. Then, a mixture of acetonitrile (as a dispersive solvent) and magnetic ionic liquid (as an extraction solvent) was rapidly injected into the obtained solution. In the following, the magnetic solvent droplets including the extracted analytes were isolated from the aqueous solution in the presence of an external magnetic field and after diluting with acetonitrile injected into high-performance liquid chromatography equipped with a diode array detector. Under the optimum extraction conditions, high extraction recovery (78%), low limits of detection (7.2 ng/g) and quantification (23.9 ng/g), good repeatability (relative standard deviations ≤5.8 and 6.8% for intra-and inter-day precisions, respectively), and wide linear range (23.9-1000 ng/g) were obtained.Finally, various fish samples marketed in Tabriz city (East Azarbaijan, Iran) were analyzed with the suggested method.

“…Regarding the chemical analysis of parabens, only two published works have reported methods involving the use of EME systems [ 11 , 30 ], while most of methods in the literature involve alternative microextraction techniques, such as solid-phase microextraction (SPME), LPME, or dispersive liquid–liquid microextraction (DLLME) procedures. Therefore, the comparative assessment focused on miniaturized protocols for the determination of parabens and FQs [ 11 , 30 , 31 , 32 , 33 , 34 ], as detailed in Table 3 .…”

A chitosan biopolymeric membrane was successfully used as a support in a green electromembrane extraction procedure for the simultaneous and selective extraction of seven parabens and three fluoroquinolones in the presence of three non-steroidal anti-inflammatory drugs. The optimal experimental conditions (10 mL donor phase and 50 μL acceptor phase, pH 10 in both phases; 80 V of applied voltage during 15 min of extraction time) were determined, providing high enrichment factors for six of the studied parabens (EF ≥ 90) and the three fluoroquinolones (EF ≥ 50). Wide linear concentration ranges (0.5–500 μg L−1), good linearity (>97%), low limits of detection (0.2–1.1 μg L−1), and good repeatability (relative standard deviation values 4–10%) were achieved. The proposed method was successfully applied for the extraction of the target analytes from different kinds of water samples (river, lake, and swimming pool). The usage of a chitosan membrane in the extraction process presents many advantages, as it is a biodegradable and versatile support, offering a good alternative to commercial plastic materials commonly used in this methodology and these procedures.

“…20,21 Dispersive liquid-liquid microextraction (DLLME) has been successfully applied in the extraction of various compounds from environmental, biological, and food samples owing to several advantages, such as being fast and simple, requiring low organic solvent usage, and exhibiting high enrichment capacity. [22][23][24][25] DLLME generally involves the use of a mixture of an extraction solvent that is immiscible with the sample, and a dispersion solvent that is miscible with both the extraction solvent and the sample. 23 Salting-out assisted dispersive liquid-liquid microextraction (SA-DLLME) involves the use of inorganic salts (NaCl, MgSO 4 , (NH 4 ) 2 SO 4 , etc.)…”
