“…Another useful LPME technique based on HF is known as HF vortex solvent bar microextraction (HF‐VSBME), which was first proposed by Huang in 2012, has been applied to separate and concentrate PEs from aqueous matrices. The short hollow fiber immobilized with organic phase serving as the solvent bar for microextraction.…”

1,2-Benzenedicarboxylic acid esters, commonly referred to as phthalate esters, form a group of compounds that are mainly used as plasticizers in polymers. Because phthalate esters are not chemically bound to the plastics, they can be released easily from products and migrate into the food or water that comes into direct contact. Due to their widespread use, they are considered as ubiquitous environmental pollutants. Phthalate esters are regarded as endocrine disrupting compounds by means of their carcinogenic effect. Phthalate esters can be analyzed by gas chromatography or high-performance liquid chromatography, however, their sensitivity and selectivity limit their direct use for determination of phthalates at very low level of concentrations exist in environmental samples with complex matrices. Therefore a sample pretreatment prior to their analysis is necessary. In this review, the historical development and overview of sample preparation methodologies have briefly been discussed and a comprehensive application of these methods in combination with different analytical techniques for preconcentration and determination of phthalate esters in various matrices have been summarized. Finally, a critical comparison of the different approaches in terms of enrichment factors achieved, extraction efficiency, precision, selectivity and simplicity of operation is provided.

“…The bottom section of the U‐shaped fiber is immersed in the sample solution for the extraction or the ends of the U‐shaped fiber are sealed, so no syringe is needed (Figure D). The method using shorter fibers sealed at both ends and free stirring in the sample solution (see Figure C) is called solvent bar microextraction (HF‐SBME) . The fiber is cut open after the extraction and its contents are analyzed.…”

This review follows up on Part 1, which focused on classification and evaluation of single drop and sorbent‐based microextraction techniques. Membrane‐ and homogenous phase‐based microextraction techniques are discussed and classified in Part 2. These techniques are more recent than those in Part 1 and considerable attention has been paid to their development. The new methodologies are more sensitive and, thanks to their miniaturization, they can be classified as “green”, but no exhaustive classification is available. We hope that this review will contribute to better orientation in these methods.

“…Its extraction efficiency is approximately 1.5-fold higher than commercial 100 µm polydimethylsiloxane (PDMS) or 65 µm PDMS/divinylbenzene (PDMS/DVB) coating fibers. No obvious extraction efficiency change after 250 extractions, thermal or different solvent treatments were observed 73 .The group of Wang used similar methods to prepare graphene-coated SPME fiber for determination of carbamate pesticides and triazine herbicides in water samples 74 …”
