AI Technical Summary
Existing technologies are difficult to use efficiently and conveniently to detect perfluorinated compounds in environmental water, especially due to their trace amounts and complexity. Furthermore, COFs synthesized by high-temperature solvothermal methods are not suitable for large-scale preparation, and room-temperature synthesis methods are limited to two-dimensional COFs. The applicability of three-dimensional COF synthesis has not been reported.
Fluorinated covalent organic framework materials were synthesized at room temperature using tetra(4-aminophenyl)methane and 2,3,5,6-tetrafluoro-p-dibenzoaldehyde. These materials were used as packing material for solid-phase extraction columns, selectively adsorbing perfluorinated compounds through fluorinophilic interactions, and then detected by liquid chromatography-tandem mass spectrometry.
It achieves efficient separation and enrichment of perfluorinated compounds, with high detection sensitivity, low cost, reusable materials, and is suitable for the simultaneous determination of multiple perfluorinated compounds. The synthesis conditions are mild and easy to scale up production.
