Article Description

Ochratoxin A (OTA) exposure in food poses great threat to human health. Magnetic solid phase extraction (MSPE) is an effective sample pre-treatment method based on liquid chromatographic analysis to monitor OTA in food. Herein, magnetic covalent organic frameworks (Fe 3 O 4 @COFs) nanospheres were prepared and well characterized. The efficient and selective extraction of OTA relied on large specific surface and inherent porosity of COFs and the hydrogen bonding, π-π and hydrophobic interactions between COF shell and OTA. The MSPE parameters were investigated in detail. Under the optimal MSPE conditions, the developed Fe 3 O 4 @DhaTab-based-MSPE-HPLC-FLD method for OTA displayed good linearity (0.1-800 μg L −1 ) with R 2 (0.996) and low limit of detection (0.03 μg L −1 ). The proposed method was applied to determine OTA in beer, Chinese Baijiu and vinegar with satisfactory recoveries (72–111%) and relative standard deviations (0.2 to 5.5%).
