AI Article Synopsis
- - Cereals often contain aflatoxins (AFs) that can be harmful, so researchers aimed to create an effective way to extract and detect these toxins quickly.
- - A new material called FeO@BB-COF was developed using a one-step process, which has multiple active sites that help it effectively capture AFs through various interactions.
- - This method is not only simple and fast (taking only 6 minutes and using just 2 mg of material) but also shows good accuracy and sensitivity for detecting aflatoxins in cereals.
Article Abstract
Cereals are frequently contaminated by aflatoxins (AFs). The objective of this study was to develop an efficient extraction materials for rapidly extracting and detecting AFs. A novel amino-functionalized benzodiimidazole linkage magnetic covalent organic framework (FeO@BB-COF) was simply fabricated by one-step cyclization and aromatization. The FeO@BB-COF, having multiple N-containing active sites, exhibited excellent extraction capability towards AFs due to synergistic interactions, including the π-π interactions, hydrogen bonding interactions, polar interactions, electrostatic interactions and Lewis acid-base interactions. The FeO@BB-COF based MSPE method for detecting aflatoxins has advantages of simple operation, short extraction time (6 min), and low material consumption (2 mg). This method exhibited satisfactory linearity (0.05-20 μg/kg), and sensitivity (0.01-0.45 μg/L for the detection limits) and accuracy (76.8-97.1 % for recovery) and was successfully applied for extracting and detecting AFs in cereals.
