“…In the ENCG/HPLC-FLD method, the existence of mNH 2 -MIL-101(Al), β-CD, and GO-based nanohybrids provide the basis for the simultaneous adsorption/extraction of trace pollutants with a wide polarity range; the effervescent reaction speeds up the dispersive process, and the The polarities of pollutants that can be tested are relatively wider; that is to say, both PAHs and BPs can be efficiently extracted simultaneously; (2) The extraction time is shorter (only 40 s); however, it requires 3-5 min [3,41] and even as long as 50 min in the previous reports [39]; (3) in contrast to the MSPE-GC-MS [41], SPME-GC-MS/MS [39], and UHPLC-MS/MS approaches [42], the present method supplies comparable LODs (0.07-0.30 μg kg −1 ) and recov- eries (86.9-103.9%), but it is simple in operation and cheap in the analytical pretreatment cost. Table S3 summarizes the detailed comparisons between the ENCG/HPLC-FLD method with other conventional methods for the determination of PAHs and/or BPs in meat samples [3,[39][40][41][42].…”

“…Polycyclic aromatic hydrocarbons (PAHs) and bisphenolic pollutants (BPs) are two types of ubiquitous pollutants, which possess environmental estrogen effects. PAHs mainly come from incomplete combustion of organic compounds, and several external and internal factors can result in their residues in many kinds of food matrices [1,2]. Especially, the intake of PAHs from all kinds of roasted meat samples is frequent and inevitable.…”

To simultaneously and efficiently extract pollutants with differential polarities, we herein fabricated and characterized a multifunctional nanocomposite. The novel nanohybrids used NiFe2O4 as magnetic cores, and NH2‐MIL‐101(Al), β‐cyclodextrin and graphene oxide as functional components combined with magnetic cores. With the aid of graphene oxide's large π‐conjugated system, NH2‐MIL‐101(Al)’s strong adsorption to moderately/strongly polar chemicals, and β‐cyclodextrin's specific recognition effect, the nanohybrids realized synergistically efficient extraction of polyaromatic hydrocarbons and bisphenols with a logKow range of 3–6. Combined with acidic and alkaline sources, the nanohybrids‐based effervescent tablets were prepared. Based on effervescent reaction‐enhanced nanohybrids‐based efficient adsorption/extraction and high performance liquid chromatography and fluorescence detection, we successfully developed an excellent microextraction method for the simultaneous determination of both polyaromatic hydrocarbons and bisphenols in roasted meat samples. Several important variables were optimized as follows: Na2CO3 and tartaric acid as acidic and alkaline sources, 900 μLof the mixed solvent (acetone and hexane at 2:1 by v/v) as the eluent, 5 min of elution time. Under optimized conditions, the novel method gave low limits of detection (0.07–0.30 μg kg−1), satisfactory recoveries (86.9–103.9%), and high precision (relative standard deviations of 1.9–6.7%) in roasted lamb, beef, pork, chicken, and sausage samples.

“…Due to low concentrations of BPs in samples, various adsorbents have been developed to preconcentrate the BPs with solid phase extraction (SPE) [ 23 ]. Electrochemical detection of bisphenols using modified electrodes (including aptamers or molecularly imprinted polymers) is another popular method [ 24 , 25 ]. These kinds of approaches offer even lower detection limits than the HPLC methods, but they are difficult to transfer for commercial purposes.…”

Analytical methods using the fluorescence properties of bisphenols (BPA, BPF and BPS) and their complexes with β-cyclodextrin and methyl-β-cyclodextrin were developed. The methods were applied for the analysis of thermal paper and canned food. Their performance was compared with a standard HPLC approach with a diode array and fluorescence detections. For comparison purposes, basic validation parameters (linear range, limit of detection, sensitivity, precision) were evaluated. It was concluded the developed methods facilitate fast and cost-effective determination of three bisphenol species in liquid samples, similar to the HPLC performance. They are also environmentally friendly. BPA, BPF and BPS can be routinely determined with the presented approach.

“…The size and shape of the imprints obtained are the same as those of the molecules used as a compound for their preparation. Molecularly imprinted polymers are promising sorbents for separation because they exhibit high affinity and selectivity similar to receptors for target molecules [ 13 , 15 ]. The latest reports from the literature [ 16 , 17 , 18 ] indicate that the molecular imprinting technique is an increasingly developing branch of material engineering that produces materials in various forms, for example, monoliths, membranes, or core-shell sorbents.…”

The membrane emulsification process (ME) using a metallic membrane was the first stage for preparing a spherical and monodisperse thermoresponsive molecularly imprinted polymer (TSMIP). In the second step of the preparation, after the ME process, the emulsion of monomers was then polymerized. Additionally, the synthesized TSMIP was fabricated using as a functional monomer N-isopropylacrylamide, which is thermosensitive. This special type of polymer was obtained for the recognition and determination of trace bisphenol A (BPA) in aqueous media. Two types of molecularly imprinted polymers (MIPs) were synthesized using amounts of BPA of 5 wt.% (MIP-2) and 7 wt.% (MIP-1) in the reaction mixtures. Additionally, a non-imprinted polymer (NIP) was also synthesized. Polymer MIP-2 showed thermocontrolled recognition for imprinted molecules and a higher binding capacity than its corresponding non-imprinted polymer and higher than other molecularly imprinted polymer (MIP-1). The best condition for the sorption process was at a temperature of 35 °C, that is, at a temperature close to the phase transition value for poly(N-isopropylacrylamide). Under these conditions, the highest levels of BPA removal from water were achieved and the highest adsorption capacity of MIP-2 was about 0.5 mmol g−1 (about 114.1 mg g−1) and was approximately 20% higher than for MIP-1 and NIP. It was also observed that during the kinetic studies, under these temperature conditions, MIP-2 sorbed BPA faster and with greater efficiency than its non-imprinted analogue.
