In this paper, a simple and effective method for the determination of six macrolide antibiotics (MACs), including tylosin, tilmicosin, azithromycin, clarithromycin, roxithromycin, and kitasamycin, in the chicken sample using liquid chromatography-tandem mass spectrometry (LC-MS/MS) was developed based on a self-built porous aromatic framework- (PAF-) based solid phase sorbent. The main parameters influencing the extraction efficiency, such as sorbent amounts, type of the eluent, pH of the sample, and the eluent volume, were evaluated. Under the optimized condition, the limits of detection were from 0.2 to 0.5 μg·kg−1. The recoveries of the method ranged from 82.1% to 101.4% with the relative standard deviations less than 11.1%. All the results demonstrated that the established method is potential for the determination of macrolide antibiotics in food safety analysis and monitoring.

“…In recent years, porous materials stand out among numerous absorbents on account of their outstanding performance in the sample pretreatment, especially porous aromatic frameworks (PAFs) which has larger surface area and larger π-π conjugate system as well as a simple preparation procedure 31,32 . Our group has been committed to the research of COFs in recent years, and a novel multi-interaction and mixed-mode porous aromatic frameworks PAF-6 has been synthesized 33 and used as SPE adsorbent to extract and determine bisphenol A (BPA) in milk and its packing samples. The results show that PAF-6 has an excellent adsorption capability for BPA based on hydrogen bonding and the inclusion interactions of host-guest.…”

In this paper, a simple and easy method of solid phase extraction (SPE) followed by capillary electrophoresis (CE) with capacitively coupled contactless conductivity detection (C4D) is evaluated as a novel approach for the simultaneous determination of acesulfame-K (ACE), sodium saccharin (SAC), and sodium cyclamate (CYC) in foodstuffs without derivatization. To reduce the complex matrix interference resulting from the constituents of samples and enriched targets, porous aromatic frameworks (PAFs) enhanced SPE, a suitable sample pretreatment procedure, was introduced. Several factors affecting extraction efficiency and electrophoretic separation were investigated. Additionally, the interaction mechanisms between the host (PAF-6) and guests (ACE, SAC, and CYC) were studied. Under the optimum conditions, three sulfanilamide artificial sweeteners were baseline separated within 8 min, exhibiting a linear calibration over two orders of magnitude (R2 > 0.995). The limits of detection (LOD) and quantification (LOQ) were considered better than those usually obtained by CE with ultraviolet and C4D detection. The proposed SPE–CE–C4D method has been successfully applied to analyse beverage samples and candied fruits with recoveries in the range of 78.89%–92.00%.

“…So, developing a suitable sample preparation technique which can improve reliability of analysis results is very necessary. Generally, different kinds of extraction step have been claimed for separation and preconcentration trace concentration of BPA such as solid phase extraction (SPE), liquid‐liquid extraction (LLE), hollow fiber‐liquid phase microextraction (HF‐LPME), molecularly imprinted SPE (MISPE)and stir bar sorptive extraction (SBSE) ,. However, these extraction technologies have some limitations, such as LLE has disadvantages of the loss of target and solvent‐depending .…”

In the present study, an electrochemiluminescence quenching approach coupled with magnetic enhanced solid phase microextraction was exploited for the extraction and determination of bisphenol A. The GO‐Fe3O4 nanocomposites as solid phase microextraction sorbent were synthesized for extraction of bisphenol A. It was found that the magnetic field applied using an external magnet can not only achieve rapid separation, but also enhance the extraction efficiency to some extent. The GO−Au nanoparticle (GO‐AuNPs) composites combine the advantages of large specific surface area of graphene oxide and good conductivity of Au nanoparticles. Thus, an electrochemiluminescence sensor was constructed by immobilization of GO‐AuNPs composites on glassy carbon electrodes (GCE). Bisphenol A could quench GO‐AuNPs composites enhanced electrochemiluminescence signal of luminol during the detection stage. Under optimized experimental conditions, the quenched electrochemiluminescence intensity was linearly proportionally to the negative value of the logarithm of the concentration of bisphenol A within the range of 10−8∼10−4 mol/L, with a correlation coefficient r of 0.9920 and a limitation of detection of 4.2×10−9 mol/L. This method can be used to detect bisphenol‐A in real samples, meanwhile its sensitivity was higher based on the enhancing effect of luminol by GO‐AuNPs composites and extraction of target before detection.
