Tetracyclines (TCs) are a prevalent type of broad-spectrum antibiotic, which could pose a great threat to human health. Herein, ZIF-8 modified carbon cloth (ZIF-8/CC) for electric field-enhanced thin-film microextraction (EE-TFME) of TCs (oxytetracycline, tetracycline and doxycycline) was developed. ZIF-8/CC was prepared by growing ZIF-8 in situ on the surface of CC as the positive electrode of EE-TFME. Compared to the bare carbon cloth electrode, the ZIF-8/CC electrode can enhance the TCs extraction capacity up to nearly twice. Furthermore, EE-TFME could reduce the extraction equilibrium time from 30 min to 20 min. The detection limit of combined high performance liquid chromatography (HPLC) was 2.0-2.5 ng/mL, and the RSDs of intra-day and inter-day were all below 7.1%. The EE-TFME-HPLC method developed based on ZIF-8/CC can be successfully applied to detection of TCs in honey and milk. The spiked recovery experiments of 50 ng/g and 100 ng/g were carried out on milk and honey samples, and the recovery rate of all TCs was between 82.4% and 102.9%, RSDs were less than 8.2%.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
