Περίληψη: The accumulation of bisphenols through the food chain could cause severe harm to human health. Therefore, the sensitive detection of trace bisphenols in environment is very important for environmental monitoring and public health. Compared with offline extraction methods, online solid-phase extraction (SPE) displayed the advantages of convenient operation and high precision. Furthermore, extraction materials with satisfactory enrichment performance are the most important for online SPE. Covalent organic framework (COF) aerogels represent a novel class of advanced materials, and the introduction of functional groups can improve their properties. Hence, this work prepared a fluorinated COF aerogel (COF-ATFTA), a fluorine-free COF aerogel (COF-APDA) and a fluorinated COF powder (COF-PTFTA) at room temperature, which were characterized with SEM, XRD, XPS and other means. Some model analytes were selected to investigate these materials through online SPE, COF-ATFTA displayed highest enrichment factors (1130-2271) than other two materials, based on large surface area, hierarchical pore structure, and multiple interactions (π-stacking, hydrophobic, hydrogen-bonding and F-F interactions). Subsequently, COF-ATFTA was used as adsorbent to study adsorption performance toward bisphenols, and displayed the adsorption capacity of 157-195 mg/g for four bisphenols. The adsorption process was dominated by chemical adsorption according to the adsorption kinetics model. By coupling COF-ATFTA-based online SPE with high-performance liquid chromatography-diode array detection (HPLC-DAD), an online SPE-HPLC-DAD analytical method was established to detect bisphenols in water samples. Compared with other methods, the analytical method had lower detection limits (0.01-0.05 μg/L) and broad linear ranges (0.033-20.0 μg/L). The research introduced the COF-ATFTA for online enrichment and analysis of bisphenols, which broadened the application of COF aerogels in the sample preparation and environmental detection fields.
