“…As it can be observed, the developed methodology using BAμE devices coated with sucrose-based hydrochar presents similar or better recovery yields than other miniaturized enrichment techniques, e.g., SBSE coated with PDMS, PA or EG [38] or SBME coated with C8 polymer [39] for the extraction of carbamazepine; TFME coated with PDMS [44] for the extraction of 17--estradiol; SBSE coated with PDMS [42] for the extraction of clofibric acid; SBSE coated with PU [45] for the extraction of diclofenac, gemfibrozil or mefenamic acid. Additionally, the BAμE(npHS)-μLD/HPLC-DAD methodology sensitivity is similar when compared to analogue instrumental systems [37,39,45] and/or some mass spectrometry or tandem mass 26/40 spectrometry instrumental systems [40,44]. On the other hand, instrumental apparatus that employ mass spectrometry or tandem mass spectrometry expectedly presented lower LODs than the proposed technique [38,41,44,46].…”

“…A comparison of the performance of the BAμE(npHS)-μLD/HPLC-DAD methodology and other established static-based microextraction techniques is shown in table 3 [36][37][38][39][40][41][42][43][44].

Thirteen carbon materials comprising commercial activated carbons and labmade materials (hydrochars and activated carbons) were assayed as enrichment phase in bar adsorptive microextration to monitor trace levels of ten common pharmaceutical compounds (PhCs) in environmental water matrices, 2/40 including surface water, sea water, tap water and wastewater. Polar and nonpolar pharmaceuticals were selectedsulfamethoxazole, triclosan, carbamazepine, diclofenac, mefenamic acid, 17α-ethinylestradiol, 17β-estradiol, estrone, gemfibrozil and clofibric acidas model compounds to cover distinct therapeutic classes. Despite having a less-developed porosity, data showed that "in-house" prepared nanoporous hydrochars obtained from carbohydrates at low temperature (e.g., 180 ºC) in the presence of an eutectic salt mixture compete with the best commercial activated carbons for this particular application. The combination of a micro and mesopore network with a rich oxygen-based surface chemistry yielding an acidic nature allowed these hydrochars to present the best overall recoveries (between 20.9 to 82.4 %) for the simultaneous determination of the ten target PhCs with very distinct chemical properties, by high performance liquid chromatography-diode array detection (HPLC-DAD).

“…The preconcentration factors were calculated by the equations provided in the sub‐section 2–5, and they revealed that the method provided preconcentration factors in the range of 47–53. The comparisons made between the developed method and some other microextraction techniques used for determination of the understudied drugs in terms of the speed, extraction recovery, LOD, and preconcentration factor (Table ) showed that the proposed method was very fast so that it was accomplished in just about 5 min . The final analyzer system used in the method was HPLC‐UV.…”

A simple method is introduced providing a highly clean microextraction for the determination of some anti‐inflammatory drugs as the model analytes in human urine and environmental matrices. This method is based upon the implementation of two consecutive emulsification liquid‐phase microextractions, which are separated by a syringe filtration step. In this method, the organic extraction solvent (dihexyl ether) is dispersed into the aqueous sample solution (20 mL), and the resulting cloudy mixture is passed through a hydrophilic polytetrafluoroethylene syringe filter. By this action, the extraction phase containing the analytes and many interfering species that could be transferred into the organic phase is retained behind the hydrophilic membrane. The filter is then detached from the syringe and attached to another syringe containing an aqueous solution (pH 12.0, 150 μL), and by the in‐syringe dispersion of the organic phase into the aqueous phase, the analytes are selectively back‐extracted into the aqueous phase. The developed method is centrifuge‐free and very simple, and provides a high sample clean‐up in a few minutes. Under the optimized experimental conditions, the developed method provided a linearity in the range of 2.0–2000 ng/mL, a low limit of detection (0.5 ng/mL), and enrichment factors of 47–53.
