“…For instance, Zhang et al proposed a jacket-free configuration of SBSE, where a thin extraction phase is deposited directly on a stainless steel wire. The main challenge faced by researchers in this endeavor revolved around the difficulties related to chemical immobilization of the extractive phase on the relatively inert stainless steel surface . To prepare a stable coating, the researchers first modified the wire surface with a stable layer of polydopamine via an in situ polymerization reaction.…”

“…It can be seen from the comparison, the LODs of SIM, ATO, ATZ, TEM, and PRO obtained by the proposed method are lower than that achieved by other methods with the same kind of detector [11,13,14,28,29,31,33,36-38, 40,41]. Typically, for the determination of triazines, higher sensitivity can be achieved when high sensitivity detectors such as MS [19][20][21] and FD [22] are used. For example, SPE-GC-MS [30], dispersive micro (Dμ)-SPE-UHPLC-MS [32], and IT-SPME-LC-MS-MS [35] show better sensitivity than our method.…”

“…Polydopamine (PDA), inspired by the highly bio‐adhesive ability of mussels, has been developed as a versatile surface modification protocol. Based on the outstanding properties, PDA has been used as adsorbents in SBSE , SPME , and MSPE . The previous results indicate that PDA is an ideal material for sample preparation.…”

A new multiple monolithic fiber solid-phase microextraction using a polydopamine-based monolith as the extraction medium is proposed. The monolith was synthesized by facile in situ copolymerization of N-methacryldopamine and dual cross-linkers (divinylbenzene/ethylenedimethacrylate) in the presence of N,N-dimethylformamide. The effect of the contents of N-methacryldopamine and porogen in the polymerization mixture on the extraction performance was investigated thoroughly. A series of characterization studies was performed to validate the structure and properties of the monolith. The prepared multiple monolithic fibers were used for the extraction of triazine herbicides in environmental water samples. After the optimization of the extraction parameters, a convenient, sensitive, cost-effective, and environmentally friendly method for the determination of trace triazine herbicides in water samples was developed by coupling multiple monolithic fibers solid-phase microextraction with high-performance liquid chromatography and diode array detection. The results indicated that the limits of detection and quantification for the target compounds were 0.031-0.14 and 0.10-0.45 μg/L, respectively. Good precision and reproducibility were obtained with the relative standard deviations below 10%. The developed method was applied to the analysis of the triazine herbicides in different water samples (lake, river, and farmland waters). The recoveries of the method were in the range between 79.6 and 117%.

“…In SBSE, the sorbent is coated onto a magnetic stirrer, and the analytes are extracted when the stir bar stirs the aqueous solution . Many coatings have been developed for SBSE, such as commercial poly(dimethylsiloxane) coating , molecularly imprinted polymers , organic–inorganic coating , monolithic coating , metal–organic framework , carbon nanotubes , graphene , and so on by chemical polymerization, sol–gel, and covalent immobilization methods.…”

Stir bar sorptive extraction is an environmentally friendly microextraction technique based on a stir bar with various sorbents. A commercial stirrer is a good support, but it has not been used in stir bar sorptive extraction due to difficult modification. A stirrer was modified with carbon nanoparticles by a simple carbon deposition process in flame and characterized by scanning electron microscopy and energy-dispersive X-ray spectrometry. A three-dimensional porous coating was formed with carbon nanoparticles. In combination with high-performance liquid chromatography, the stir bar was evaluated using five polycyclic aromatic hydrocarbons as model analytes. Conditions including extraction time and temperature, ionic strength, and desorption solvent were investigated by a factor-by-factor optimization method. The established method exhibited good linearity (0.01-10 μg/L) and low limits of quantification (0.01 μg/L). It was applied to detect model analytes in environmental water samples. No analyte was detected in river water, and five analytes were quantified in rain water. The recoveries of five analytes in two samples with spiked at 2 μg/L were in the range of 92.2-106% and 93.4-108%, respectively. The results indicated that the carbon nanoparticle-coated stirrer was an efficient stir bar for extraction analysis of some polycyclic aromatic hydrocarbons.
