“…With the aid of an electric or magnetic field, better extraction performance can be achieved. Electric field-enhanced SPME has been used for the fast extraction and desorption of polar aromatic amines (AAs) and phenoxycarboxylic acids herbicides (PCAHs), and their precise quantifications at trace level have been realized. , On the other hand, magnetic nanoparticles (Fe 3 O 4 ) have been composited with other polymers and further in situ polymerized in a capillary for IT-SPME. The fabricated monolithic adsorbents present porous and super paramagnetic properties and possess abundant functional groups, which have exhibited satisfactory performance for the capture of inorganic species (mercury, chromium, and selenium).…”

“…It will be better if the fabrication method is universal. Moreover, the prepared SPME devices can be further assisted by other extra energies, such as electricity and magnetism, realizing fast mass transfer. − It can be seen that the coating material, coating fabrication method, and extraction device design are three key aspects for the enhanced extraction performance of SPME, and these are constantly being innovated. Finally, these fabricated SPME devices can be combined with diverse instruments to develop analytical methods for the precise quantification of trace target analytes or identification of biomarkers from abundant untargeted analytes …”

“…The coating material of the membrane used as the extraction phase decides the analytical performance of TFME [14]. Recently, a series of sorbents including polydimethylsiloxane membrane [15], modified cellulose paper [16], C18-polyacrylonitrile film [17], porous monolithic composite [18], nanofiber sheet [19], carbon mesh supported membrane [20], and metal-organic frameworks [21] have been developed for the extraction of target compounds in various types of matrices. These solid phases are synthesized via solvothermal reaction with organic materials and reagents [22], and then fabricated by spraying, dipping, or electrospinning onto a fiber or film surface [23,24].…”

A novel solid-phase microextraction device coated with an efficient and cheap thin film of polyurethane was developed for trace determination of 13 widely used pesticides in fruit and tea beverages. A round-shaped polyurethane film covering the bottom of a glass vial was fabricated as the sorbent to exhibit a superior capacity for preconcentrating target compounds and reducing matrix interferences. After optimization of the key parameters including the film type, extraction time, solution pH, ionic strength, desorption solvent, and conditions, this device allowed an efficient adsorption-desorption cycle for the pesticides accomplished in one vial. Coupled with gas chromatography-electron capture detection, the polyurethane-coated thin film microextraction method was successfully established and applied for the analysis of real fruit and tea drinks, showing low limits of detection (0.001-0.015 μg/L), wide linear ranges (1.0-500.0 μg/L, r 2 > 0.9931), good relative recoveries (77.2%-106.3%) and negligible matrix effects (86.1%-107.5%) for the target pesticides. The proposed approach revealed strong potential of extending its application by flexibly modifying the type or size of the coating film. This study provides insights into the enrichment of contaminants from complex samples using inexpensive and reusable microextraction devices that can limit the environmental and health impact of the sample preparation protocol.

“…[1][2][3] In the typical molecular structure of phenoxyacetic acid, there are aromatic rings and a carboxylic side chain. [4][5] Due to high solubility and stability in water, phenoxyacetic acid herbicides are present in surface water such as lakes, rivers, and wastewaters. [6][7] The residual herbicides in water could lead to uncontrolled growth of meristematic and prevention of protein synthesis.…”

A novel sorbent (SiO2‐(CH2)3‐DABCO) for solid‐phase extraction (SPE) was successfully prepared by chemical‐bonding formation of diazabicyclo[2.2.2]octane ionic liquid onto silica gel. The structure of SiO2‐(CH2)3‐DABCO sorbent was characterized by FT‐IR, TGA, SEM, EDX, and BET methods. Cartridges packed with the synthetic SiO2‐(CH2)3‐DABCO were used for the preconcentration of trace‐level of phenoxyacetic acid herbicides in water samples for the first time. The factors influencing on the recovery were investigated, such as type of ion liquids, loading volume, eluents, elution volume, loading rate, and capacity. After the enrichment, the phenoxyacetic acid herbicides were analyzed by high‐performance liquid chromatography with an ultraviolet detector. Four model phenoxyacetic acid herbicides, including 2‐methyl‐4‐chlorophenoxyacetic acid (MCPA), 2,4,5‐trichlorophenoxyacetic acid (2,4,5‐T), fenoprop (2,4,5‐TP) and haloxyfop were well retained and separated by this material with a recovery efficiency from 77 to 103 %. The SiO2‐(CH2)3‐DABCO demonstrated a good capacity corresponding to 0.56 mg of the analyte adsorbed per 100 mg of the material. The mixture of phosphate buffer (pH 7) : MeOH (50 : 50, v/v) was used to elute the analytes and provided the highest recovery with the standard deviations from 2.4 to 6.5. The high sensitivity with detection limits of 1.070–9.587 μg/L can be achieved.
