“…Both plastic samples including the transparent box and foam box were obtained from a local snack bar (Zunyi, China). The sample pretreatment method was followed according to a previous report with slight modifications [25]. First of all, the plastic samples were washed with pure water thrice and chopped into small pieces.…”

“…Facing the increasing health risk of bisphenol residues, developing a simple and sensitive method for the quantitative analysis trace BPs is meaningful for human health assessments. At present, some sample pretreatment techniques for the determination of BPs from different samples mainly rely on SPE [24], SPME [25], and MSPE [26]. There have been still no reports focusing on the development of online sample preparation methods based on highly selective COFs as enrichment media for analysis of BPs.…”

Covalent organic frameworks with tunable porous crystallinity and outstanding stability have exhibited fascinating pretreatment performance as ideal extraction media. Herein, the β-ketoenamine-linked TpPa-1 synthesized by 1,3,5-triformylphloroglucinol and paraphenylenediamine was employed as the absorbent for online micro-solid phase extraction of trace bisphenols combined with high-performance liquid chromatography detection. A series of characterizations indicated that the TpPa-1 possessed large surface areas, high stability, and hydrophobicity. The main experimental parameters affecting the extraction efficiency were optimized in detail. Compared with four commercial sorbents, the TpPa-1 exhibited superior enrichment capacity for extracting bisphenols. Under the optimum conditions, the established method demonstrated a wide linear range and high sensitivity with the limit of detection ranging from 0.05-0.06 μg/L. Furthermore, the developed method was successfully applied to determine bisphenols in plastic samples. Bisphenol A was actually detected in a transparent box with a concentration of 0.31 μg/g, and the recoveries of the four bisphenols in the plastic samples were 80.5-116% with the relative standard deviation less than 9.2%. Such performance was attributed to recognition affinity, including the ππ affinity, hydrophobic effect, and hydrogen bond. These results demonstrated that TpPa-1 possessed great potential to be an excellent pretreatment medium for online separation and analysis of trace analytes in complex samples.

“…Sample preparation routes for analytical detection systems have been investigated for decades to enhance the selectivity, along with methods for the direct determination of various analytes (Hosseini et al, 2017; Jafari & Amani, 2018; MacCallum et al, 1997; Sereshti et al, 2017). Solid‐phase microextraction (SPME) is a sample pretreatment methodology primarily introduced by Pawliszyn in 1990 (Cui et al, 2009; Pang et al, 2020). This sample preparation method presents some advantages in comparison withnormal sample preparation methods like solid‐phase extraction and liquid–liquid extraction techniques.…”

Polyaniline nanofiber films were fabricated on the surface of stainless steel wire via a controllable and simple electrophoretic deposition route from a nonaqueous colloidal suspension consisting of polyaniline nanofibers. The prepared coating material was then characterized by field emission scanning electron microscopy equipped with energy dispersive spectroscopy and elemental mapping analysis. The fabricated polyaniline film-coated stainless steel wire was then utilized as an effective and novel sorbent phase for solid-phase microextraction of tamoxifen for subsequent gas chromatography/flame ionization detection of this anticancer drug. Parameters consisting of the temperature, extraction time, salt concentration, agitation speed, pH, temperature and time of desorption were studied and optimized using a one-at-a-time strategy. Under the optimum conditions, detection limit (S/N = 3), the limit of quantification (10/3 limit of detection), linear dynamic range, repeatability and reproducibility values of 0.51 μg L À1 , 1.7 μg L À1 , 2-1,130 μg L À1 , 5.7% and 8.6% were attained, respectively. The prepared fiber can preserve 90% of its efficacy after 20 consecutive cycles, demonstrating the suitable thermal stability and cyclability of the proposed solid-phase microextraction coating material for the determination of tamoxifen by gas chromatography/flame ionization detection. The route was effectively utilized to determine tamoxifen in urine samples, with relative recoveries ranging from 89 to 106%.

“…Furthermore, researches also has been indicated the potential of BPh-A to disrupt thyroid hormone action [20], to cause proliferation of human prostate cancer cells [21] and to block testosterone synthesis [22] at very low part-per-trillion doses So, there are needs for introducing of new analytical procedures particularly application of modern sample preparation methods (such as microextraction techniques) in order to have reliable tools for control of human exposure to BPh-A. SPME with commercial fibers was utilized for extraction of BPh-A frequently [23][24][25][26][27]. Molecularly imprinted polymeric fiber was employed for selective extraction of BPh-A from complex matrix which was shown by Tan et al [28].…”

In this research nanostructural poly (o-aminophenol) was synthesized by electropolymerization and used for solid phase microextraction procedure (SPME). Thin film of Poly (o-aminophenol) (4 µm thickness) was shaped by sweep potential for 45 min on the surface of stainless steel wire. Polymer was synthesized by potentiostat procedure too. Prepared polymer by sweep potential procedure showed nanostructures on the surface. Acetic anhydride was employed for derivatization of bisphenol A (BPh-A) and analysis of acetylated BPh-A was utilized by gas chromatography-flame ionization detector (GC-FID). Affecting parameters on derivatization and extraction such as amount of acetic anhydride, stirring rate, temperature, ionic strength and extraction time were optimized. The limit of detection (LOD) and relative standard divisions (RSDs%) were achieved 0.6 µgL-1 and less than 6.8%, respectively under optimized conditions. Finally proposed method was used for extraction of bisphenol A from leaching of baby and drinking water bottles. Relative recovery was achieved 98% for leaching from drinking bottle. In leaching from plastic baby bottle, bisphenol A (BPh-A) was detected in the range 5–15 µg L-1.
